7 FullContact Alternatives: Data Enrichment and Identity Solutions for Every GTM Need (2026)

FullContact is a privacy-safe identity resolution platform that helps US enterprises unify fragmented customer data through its Person-Centered Graph.

With 248 million U.S. consumer profiles, 900+ enrichment attributes, and sub-150ms API responses, it serves as a reliable infrastructure layer for brands, publishers, and MarTech platforms that need to resolve anonymous identifiers into persistent customer profiles.

But as your go-to-market needs evolve, FullContact's focused approach leaves gaps. Its identity graph covers only US-based people. It offers no outbound prospecting or sales engagement. And its enterprise-only pricing for core products (Resolve, Enrich, Identity Streme) creates friction for teams that want transparent, self-serve access.

This guide explores FullContact alternatives that fill those gaps, whether you need to:

• Access B2B data with AI-powered intelligence across the full go-to-market workflow

• Prospect into European and global markets with GDPR-compliant contact data

• Enrich and activate leads natively inside your HubSpot CRM

• Combine data enrichment with multichannel sales engagement in a single platform

• Access self-serve contact data without enterprise sales cycles

• Build custom data products with developer-first infrastructure at scale

• Improve enrichment coverage through multi-source waterfall queries across 20+ vendors

This isn't about finding a "better" platform. It's about finding the right fit for your data, enrichment, and activation needs. Some businesses might complement FullContact with one of these tools; others might replace it entirely.

What is FullContact?

FullContact is a privacy-safe Identity Resolution SaaS platform that helps businesses understand their customers beyond a name and email address.

Built around a proprietary Person-Centered Graph that maps fragmented online and offline identifiers into persistent PersonIDs, FullContact serves MarTech platforms, enterprise brands, and publishers who need to unify siloed customer data while maintaining privacy compliance.

Its key features include:

• Acumen for lead identification, converting anonymous website visitors into identified prospects

• Resolve for identity resolution, unifying customer and prospect data across fragmented systems

• Enrich for data enrichment, appending 900+ data attributes to customer records across demographics, professional attributes, consumer affinities, and more

• Identity Streme for first-party data management, providing an encrypted environment to ingest, obfuscate, and store customer data

• Real-time API responses in less than 150 milliseconds

• SOC2 Type II certification, CCPA and GDPR compliance, and a consumer-facing privacy portal

FullContact's identity graph contains 248 million U.S. consumer profiles with 50+ billion identifiers and processes 200 million daily updates. The platform uses confidence-based matching with tunable thresholds and a Human-in-the-Loop process for edge cases, backed by patented identity resolution technology.

However, FullContact's focus on privacy-safe identity resolution within US borders means it falls short for teams that need global data coverage, outbound sales engagement, or transparent self-serve pricing. The platform does not do business with companies looking for identity resolution outside of the United States, does not sell lists or audiences, and requires sales contact for pricing on all core products except Acumen.

That's why we focused on alternatives that address specific use cases where FullContact's approach leaves gaps.

How We Curated Our List of FullContact Alternatives

After testing FullContact and researching the data enrichment and identity resolution market, we focused on tools that address specific limitations businesses encounter as their go-to-market needs grow. While FullContact handles privacy-safe identity resolution well for US enterprises, some businesses need more:

• B2B data combined with AI intelligence that reveals why deals move or stall

• Prospecting into European and global markets where FullContact does not operate

• Lead enrichment and visitor identification inside their existing CRM without API integration

• Data enrichment and sales engagement combined to cut multi-vendor complexity

• Verified contact data through self-serve workflows without enterprise sales cycles

• Developer-first infrastructure and flexible data licensing for custom data products

• Better enrichment coverage by querying multiple vendor databases in sequence

Each tool on this list leads in one of these areas. You might use them alongside FullContact or switch entirely, depending on what your business needs.

1. ZoomInfo — Best Alternative for B2B Data and AI-Powered GTM Intelligence

ZoomInfo is an all-in-one AI GTM platform built on a large data foundation: 500M contacts, 100M companies, 135M+ verified phone numbers, 120M direct-dial phone numbers, and 200M+ verified business emails. Its key features include:

• B2B data: 120M direct-dial phone numbers, 200M+ verified business email addresses, up to 95% accuracy on first-party data, and 300+ company attributes for market segmentation

• GTM Context Graph: An intelligence layer that processes 1.5B+ data points daily, combining ZoomInfo's B2B data with CRM records, conversation transcripts, and behavioral signals to reveal why deals move or stall

• Buyer Intent Data: ZoomInfo Intent tracks signals from 210 million IP-to-Organization pairings and 6 trillion+ new keyword-to-device pairings sourced monthly

• Multiple access points: APIs and MCP for any tool or AI agent, GTM Workspace for sellers, and GTM Studio for marketers and RevOps

Where FullContact positions itself as a privacy-safe identity resolution infrastructure layer for US consumer profiles, ZoomInfo delivers a complete go-to-market intelligence platform that pairs B2B data with AI-powered insights and execution across every GTM workflow.

Why Choose ZoomInfo Over FullContact for B2B Data and GTM Intelligence

FullContact resolves fragmented consumer identifiers into unified profiles. ZoomInfo delivers a broader and deeper B2B intelligence layer. Here's where ZoomInfo differs.

B2B Data: Depth and Scale Beyond Identity Resolution

FullContact's identity graph contains 248 million U.S. consumer profiles with 900+ enrichment attributes spanning demographics, consumer affinities, financial indicators, and professional data. It resolves who a person is across fragmented identifiers.

ZoomInfo's data platform operates at a different scale and for a different purpose: 500M contacts, 100M companies, 135M+ verified phone numbers, 120M direct-dial phone numbers, and 200M+ verified business emails, all built for B2B go-to-market execution.

Source: ZoomInfo Data

ZoomInfo's data spans three dimensions: identity data (who buyers are and how to reach them), company context (org charts, technographics tracking 30,000+ technologies), and dynamic signals that reveal when accounts are actively in-market. The data flows through a multi-source verification pipeline backed by 300+ human researchers and automated scanning of 28 million site domains daily.

The quality difference shows in third-party validation. In a Fortune 500 competitive RFP analyzing 25 million contacts across vendors, an independent consultant concluded that "no other competitor came even close." ZoomInfo was named a Leader in the Forrester Wave for Intent Data Providers B2B (Q1 2025) and holds 133 No. 1 rankings on G2.

FullContact does not provide direct-dial phone numbers for outbound prospecting, does not track technographic data, and does not offer org chart visualization. For B2B sales and marketing teams, ZoomInfo's data breadth means one platform covers contacts, company context, org charts, and technographics, removing the need to stitch together multiple vendors.

⚡ZoomInfo in Action: Your sales team is targeting mid-market SaaS companies evaluating CRM solutions. ZoomInfo surfaces companies showing CRM evaluation intent signals, identifies the buying committee with verified direct dials and business emails, maps the org chart, and reveals which technologies they currently use, all from one platform.

With FullContact, you'd resolve the identity of contacts you already have but would need separate tools for intent data, technographics, and outbound contact discovery.

The GTM Context Graph: Intelligence That Explains Why Deals Move

FullContact enriches records with static attributes: demographics, professional history, consumer affinities, and email engagement signals. These describe who a person is and has been. ZoomInfo's GTM Context Graph captures not just what happened in a deal, but why it happened.

Source: ZoomInfo Context Graph

The GTM Context Graph unifies ZoomInfo's B2B data with CRM records, conversation transcripts from Chorus (ZoomInfo's conversation intelligence engine), email interactions, and behavioral signals.

Source: ZoomInfo Chorus

As ZoomInfo's CPO Dominik Facher explains: "The CRM recorded the state change. It has no record of why it happened." Maybe the CFO joined the last call and asked about ROI; that accelerated the deal. Maybe the VP went quiet for eight days during an internal budget fight; that nearly stalled it.

This contextual reasoning powers every downstream action: AI-drafted outreach addresses the specific concern a stakeholder raised, GTM plays target accounts matching your actual win patterns, and forecasts weight deals by buying evidence rather than stage labels.

FullContact does not offer conversation intelligence, deal analysis, or predictive reasoning about account behavior. Its enrichment returns data points; ZoomInfo's intelligence layer explains what those data points mean for your next action.

⚡ZoomInfo in Action: A prospect's CFO joins a call and asks detailed questions about implementation timelines. ZoomInfo's GTM Context Graph recognizes this as a buying signal that matches closed-won deals in your segment, cross-references it with third-party signals showing the company is researching a competitor, and surfaces this as a high-priority action in GTM Workspace with a pre-drafted follow-up addressing the CFO's specific concerns. No manual research, no toggling between tools.

Universal Access: Use Intelligence in Any Tool, Any Workflow

FullContact delivers data through a RESTful API, batch processing via Cipher FTP, and Snowflake External Functions. It's a data access layer that feeds other systems. ZoomInfo provides the same programmatic access through its Enterprise API and adds three access points:

• APIs and MCP expose ZoomInfo's data and GTM Context Graph to any custom agent, internal tool, or AI model, including Claude and ChatGPT.

• GTM Workspace gives sellers a single surface where prioritized accounts, AI-drafted outreach, and deal execution converge with AI agents that automate account research, CRM updates, and signal monitoring.

Source: ZoomInfo GTM Workspace

• GTM Studio gives marketers, RevOps, and GTM engineers a builder environment for audience definition, campaign orchestration, and pipeline measurement in natural language.

Customer results reflect this approach: Seismic attributed 39% of active pipeline to ZoomInfo signals and reported 54% productivity gains and 11.5 hours saved per week per seller. Snowflake achieved 200% higher conversion rates on top-scoring accounts using ZoomInfo-powered propensity models.

FullContact's architecture requires customers to build their own activation layer; ZoomInfo's includes it. The same intelligence that powers GTM Workspace for sellers flows into GTM Studio for marketers and is available via API and MCP in any third-party tool. A buying signal one team detects is immediately actionable by every other team.

⚡ZoomInfo in Action: A marketer in GTM Studio describes an audience in plain language: "Companies in financial services with 500+ employees showing intent around data governance."

Source: ZoomInfo GTM Studio

GTM Studio builds the audience using ZoomInfo's verified company data and intent signals, launches a multi-channel play, and pushes hot accounts into GTM Workspace where an AE's AI assistant has already drafted personalized outreach. The same data and context flow through every surface.

🏅 NOTE: We looked at other B2B data platforms and found that ZoomInfo's combination of data scale (500M contacts, 100M companies), the GTM Context Graph, and access through APIs, MCP, GTM Workspace, and GTM Studio creates a distinct alternative.

While 6sense and Demandbase offer strong intent and ABM capabilities, ZoomInfo's data foundation and AI-powered intelligence across the full go-to-market workflow set it apart.

ZoomInfo Pricing

ZoomInfo uses a custom-quoted, seat-and-credit-based subscription model tailored to each customer's needs. Pricing depends on number of users, monthly credit volume, features, company size, and contract length.

ZoomInfo organizes pricing into three product lines:

• Sales plans (Professional, Advanced, Enterprise) ranging from contact and company data to AI-driven account prioritization, buyer intent signals, and advanced workflows

• Marketing plans (Marketing Demand, ABM Lite, ABM Enterprise) covering audience targeting, display advertising, and full-funnel ABM orchestration

• Chorus (conversation intelligence) and Chat (website chat) available as standalone products

ZoomInfo Lite is a permanent free tier with access to 100M+ verified profiles, 10 monthly export credits, advanced search filters, a Chrome extension, and HubSpot integration, with no credit card or time limit. A 7-day free trial of the full platform is also available. API access is included in all relevant plans.

Who Should Use ZoomInfo?

Choose ZoomInfo if:

• You need verified B2B data at scale (direct-dial phone numbers, verified business emails, company context, technographics, and org charts) in a single platform rather than stitching together multiple vendors. FullContact enriches consumer and professional attributes but does not provide outbound prospecting data or the B2B company intelligence ZoomInfo offers.

• Your go-to-market strategy depends on understanding not just who your prospects are but why deals move or stall. ZoomInfo's GTM Context Graph captures the reasoning behind deal outcomes, powering AI-drafted outreach, play targeting, and forecasting at a depth no enrichment-only tool can match.

• You want intelligence accessible through any surface: a seller workspace, a marketer's orchestration canvas, or APIs and MCP in your own tools and AI agents, without the intelligence being locked into a single application.

Want B2B data with AI-powered intelligence across your go-to-market workflow? Start your free ZoomInfo trial and see what the GTM Context Graph reveals about your accounts.

2. Cognism — Best Alternative for European and Global Outbound Prospecting

Cognism is a B2B sales intelligence platform that combines GDPR-compliant contact data, phone-verified mobile numbers, and real-time buying signals for outbound prospecting across European and global markets. Its key capabilities include:

• Diamond Data phone-verified mobile numbers with 87% accuracy, boosting connect rates by up to 3x

• 200M+ European contacts with 90% coverage of Director-level contacts in Europe and the US

• DNC compliance across 15 international markets with ISO 27001, ISO 27701, and SOC 2 Type II certifications

• Bombora Company Surge intent data covering 11,000+ topics

• Chrome extension and native CRM integrations with Salesforce, HubSpot, Pipedrive, Outreach, and Salesloft

For teams with international coverage requirements, Cognism directly addresses FullContact's biggest limitation: FullContact does not do business with companies looking for identity resolution outside of the United States.

Why Choose Cognism Over FullContact for Global Outbound Prospecting?

Cognism stands out in the following areas:

• Global Data Coverage Where FullContact Cannot Operate

FullContact's identity graph covers 248 million U.S. consumer profiles, and its 3X recognition guarantee applies only to U.S.-based people.

Cognism was founded in London and built its data infrastructure with European market depth from the start: 200M+ European contacts, a database totaling 440M+ contacts and 100M+ companies globally, and 95% of director-level and above contacts refreshed every 30 days. Lead Forensics' CEO noted: "We tested a US competitor vs. Cognism for EU data. Cognism converted 60% better."

• Phone-Verified Outbound Activation

FullContact does not sell lists or audiences and provides no CRM interface, sales sequencing, or prospecting workflow. Cognism's Diamond Data includes 10M+ phone-verified contacts globally whose mobile numbers have been called and confirmed by human agents.

Source: Cognism Diamond Data

An independent study found that phone-verified numbers are 3x more likely to connect, and for high-priority prospects, Diamonds on Demand verifies a specific contact's mobile within 48 hours.

• Real-Time Buying Signals Beyond Static Attributes

FullContact enriches with static identity attributes: demographics, professional history, consumer affinities. Cognism layers contextual sales intelligence through Signal Data covering hiring trends, funding alerts, technographics (20,000+ technologies), job changes, intent data, and M&A activity, all surfaced directly in the prospecting workflow.

🏅 NOTE: We also evaluated Demandbase and 6sense. While Demandbase focuses on account-based advertising orchestration and 6sense offers predictive account scoring with intent layering, Cognism offers the strongest European data coverage, phone-verified mobile numbers, and GDPR compliance for global teams, directly addressing FullContact's US-only limitation.

Cognism Pricing

Cognism uses a custom-quote, seat-based pricing model with two tiers:

• Grow: Prospecting essentials including business emails, mobile numbers, company intelligence, CRM integrations, and up to 3 lists with 250 contacts per list

• Elevate: All Grow features plus Diamond Data phone-verified mobiles, up to 10 lists with 500 contacts per list, and buying signals including job changes, funding alerts, hiring, M&A, intent data across 12 topics, and technographic data

Add-ons include Diamonds-on-Demand for on-demand phone verification and additional intent topics beyond the standard 12. A free data sample matching your ICP is available for pre-sales evaluation.

Who Should Use Cognism?

Choose Cognism if:

• Your revenue team operates in European markets or has global coverage requirements beyond the United States, where FullContact does not operate.

• You need phone-verified mobile numbers for cold calling with 87% accuracy and 3x higher connect rates.

• Your GTM motion depends on real-time buying signals (intent data, hiring trends, funding alerts) to prioritize outreach, while FullContact enriches with static identity attributes only.

3. Clearbit (Breeze Intelligence) — Best Alternative for HubSpot-Native Enrichment and Visitor Identification

Clearbit by HubSpot (now marketed as Breeze Intelligence) is a B2B data enrichment and visitor identification platform that lives inside the HubSpot ecosystem. After HubSpot acquired Clearbit in December 2023, the product was integrated and rebranded. Its key capabilities include:

• 100+ B2B data attributes per record flowing directly into HubSpot properties

• Website visitor identification through IP intelligence feeding into HubSpot lead scoring and workflows

• Form shortening for higher conversion rates, with Greenhouse reporting a 20% increase in form completions

• Native HubSpot integration across all Hubs with no API configuration required

For teams already on HubSpot, Clearbit removes the integration complexity of connecting FullContact's API-first architecture to your CRM.

Why Choose Clearbit Over FullContact for HubSpot-Native Enrichment?

Clearbit stands out in the following areas:

• No-Friction HubSpot Integration

FullContact's API-first architecture requires development resources to map API responses to CRM fields, handle webhooks, and manage data freshness across systems. Clearbit's enrichment flows directly into HubSpot properties without custom API calls or middleware, with continuous enrichment updating records monthly and no scheduled batch jobs.

Source: Clearbit by Hubspot

• Form Conversion Optimization Built into Enrichment

FullContact enriches records after contact information has been captured. Clearbit shortens forms in real-time during submission by hiding fields that can be automatically enriched, so visitors might complete 2-3 fields instead of 10-15. As of September 2025, form shortening no longer consumes HubSpot Credits, making it a zero-cost feature.

• Bundled Pricing Within HubSpot Subscription

FullContact's core products (Resolve, Enrich, Identity Streme) have no public pricing. Clearbit's core enrichment is bundled into HubSpot: Starter, Professional, or Enterprise subscribers don't consume HubSpot Credits for data enrichment.

🏅 NOTE: We also evaluated Lusha and Apollo.io for this use case. Both offer broader multi-platform support, but Clearbit's native HubSpot integration makes it the natural fit for teams standardized on HubSpot who want enrichment without adding integration complexity.

Clearbit (Breeze Intelligence) Pricing

Clearbit operates on HubSpot's Credits system:

• Data enrichment is included at no additional credit cost for Starter, Professional, or Enterprise subscriptions

• Form shortening no longer consumes HubSpot Credits as of September 2025

• Buyer intent and smart properties consume HubSpot Credits based on usage

• Credits reset monthly, and additional capacity packs can be purchased

Source: Clearbit Credits

The trade-off: Clearbit requires the HubSpot ecosystem. You need a HubSpot Professional or Enterprise subscription for enrichment and visitor identification.

Who Should Use Clearbit (Breeze Intelligence)?

Choose Clearbit if:

• Your revenue operations are built on HubSpot and you want enrichment and visitor identification that integrates natively without development resources or middleware.

• Form conversion rates are a primary growth lever and you need to balance data collection with shorter, higher-converting forms.

• You need to identify anonymous website visitors and feed that signal into lead scoring and workflows within HubSpot, without a separate visitor tracking platform.

4. Apollo.io — Best Alternative for Combined Enrichment and Sales Engagement

Apollo.io is a B2B sales intelligence and engagement platform that replaces what historically required four or five separate vendors. Its key capabilities include:

• 270M+ contacts and 70M company database with over 65 data attribute filters

• Waterfall Enrichment querying dozens of third-party data providers sequentially for 5% more email coverage, 7% more phone numbers, and 45% lower bounce rates

• Built-in multichannel engagement including email sequences, Power Dialer and Parallel Dialer, LinkedIn automation, and voicemail drop

• Free-forever Starter plan with 75 credits per month and real prospecting capability

Where FullContact is a data infrastructure layer that does not sell lists or provide activation, Apollo bundles enrichment and engagement so users can move from finding a lead to booking a meeting without switching platforms.

Why Choose Apollo.io Over FullContact for Enrichment and Activation?

Apollo.io stands out in the following areas:

• Activation Built In, Not Bolted On

FullContact resolves identities and enriches records, then customers must push that data to a separate engagement platform to act on it. Apollo collapses this gap: find a prospect, enrich their profile, add them to a multichannel sequence, dial them with the built-in power dialer, and manage the resulting deal, all in one interface.

• Self-Serve Free Tier with Real GTM Capability

FullContact's free entry point is a one-time 1,000-match API key for developers. Apollo's Starter plan is free forever with database access, email sequences, a Chrome extension, and Gmail integration. The company's 9x revenue growth between 2021 and 2023 was driven by bottom-up, product-led adoption starting with free accounts.

• Waterfall Enrichment with Transparent Pricing

FullContact queries its single proprietary graph; if it doesn't contain a match, enrichment fails. Apollo's Waterfall Enrichment sequences queries across Apollo's database and dozens of third-party providers in a single call, increasing coverage. Pricing is published and self-serve: a Basic plan at $49/seat/month billed annually includes 30,000 credits per year.

Source: Apollo.AI Waterfall Enrichment

🏅 NOTE: We also evaluated Lusha and People Data Labs. Lusha's free tier offers basic contact reveal and People Data Labs provides developer-facing API access, but Apollo.io offers the strongest combination of free-tier enrichment, database access, and activation for teams that want to test an all-in-one platform without upfront cost.

Apollo.io Pricing

Apollo uses a per-seat subscription plus credit-consumption model:

• Free (Starter): Free forever, 75 credits/month, unlimited email credits, 2 active sequences, Gmail integration, Chrome extension

• Basic: $49/seat/month billed annually, 30,000 credits/year, Microsoft Office support, multiple seats

• Professional: $79/seat/month billed annually, 48,000 credits/year, full CRM enrichment, unlimited sequences

• Organization: $119/seat/month billed annually, 72,000 credits/year, minimum 3 seats, SSO, advanced API access

A 14-day free trial is available for paid plans.

Who Should Use Apollo.io?

Choose Apollo.io if:

• You need enrichment and activation in one platform without multi-vendor contract complexity. Apollo removes the need for a separate engagement tool alongside your data provider.

• You want a generous free tier to validate the platform before committing, especially if FullContact's enterprise-only sales motion creates procurement friction.

• You prioritize B2B sales enrichment breadth (business emails, direct dials, firmographics) over consumer identity resolution depth (household demographics, psychographics, offline-to-online stitching).

5. Lusha — Best Alternative for Self-Serve Contact Data Without Enterprise Sales Cycles

Lusha is a self-serve B2B sales intelligence platform that delivers verified contact and company data through a Chrome extension. With over 280,000 revenue teams and 1 million registered users, Lusha prioritizes accessibility over enterprise gatekeeping. Its key capabilities include:

• Instant contact reveal via Chrome extension on LinkedIn, Sales Navigator, company websites, and CRM interfaces

• Permanent free plan with 40 credits per month at no cost and no credit card required

• Job change alerts and buying signals powered by Bombora intent data across 5,000+ B2B sites

• Transparent pricing starting at $37.45/month on annual billing

Lusha serves the buyer FullContact's infrastructure-layer architecture leaves behind: individual SDRs who need contact data now, not after an API integration project.

Why Choose Lusha Over FullContact for Self-Serve Contact Data?

Lusha stands out in the following areas:

• Instant Access via Chrome Extension vs. API Integration

FullContact's core interaction model is a developer-first RESTful API requiring JSON payloads and webhook handling. Lusha's Chrome extension activates on LinkedIn profiles with one click, revealing verified phone numbers and emails in real time.

Source: Lusha Chrome Extension

Customer stories consistently cite the extension as the primary workflow: Operatix's 200 SDRs used it to double their meetings, and NEXTGEN described it as delivering contacts "without technical bottlenecks."

• Transparent Self-Serve Pricing

FullContact publishes pricing only for Acumen ($99-$300/month); Resolve, Enrich, and Identity Streme require sales contact. Lusha publishes full pricing for four of five tiers with a credit slider that shows exactly how costs scale: Starter at $37.45/month, Pro starting at $52.45/month with API access, and Premium starting at $299.95/month with AI recommendations.

• Net-New Contact Discovery vs. Identity Resolution

FullContact resolves fragmented identifiers for contacts you already have relationships with. Lusha finds contact information for prospects not yet in your database. FullContact will not provide PII that the organization doesn't already have; Lusha's entire purpose is discovering net-new contacts through searchable filters and the Chrome extension.

🏅 NOTE: We also evaluated RocketReach and Seamless.AI. Both offer similar self-serve models, but Lusha's combination of a permanent free plan, published accuracy benchmarks (98% email deliverability, 85-86% phone accuracy), and GDPR-first architecture (first B2B sales intelligence platform to receive ISO 27701 certification) delivers the fastest time-to-value for small teams.

Lusha Pricing

Lusha uses a credit-based pricing model with five tiers:

• Free: $0/month, 40 credits/month (permanent, no expiration)

• Starter: $37.45/month (annual) or $49.90/month (monthly), 400 credits/month

• Pro: Starting at $52.45/month (annual), 600+ credits/month, API access included

• Premium: Starting at $299.95/month (annual), 3,400+ credits/month, AI recommendations

• Scale: Contact sales for custom pricing with 50%+ credit discounts

Credit costs: 1 credit per email reveal, 10 credits per phone number reveal. Re-accessing previously revealed contacts costs nothing.

Who Should Use Lusha?

Choose Lusha if:

• Your team is 1-10 salespeople and you need to start prospecting this week, not after a multi-month procurement cycle.

• Your primary workflow happens on LinkedIn or Sales Navigator and you want contact data without leaving the page.

• You need to build outbound lists from scratch rather than resolve identities across fragmented existing records.

• Your target market includes EMEA or APAC regions where FullContact's US-only coverage creates a hard ceiling.

6. People Data Labs — Best Alternative for Developer-First Data Infrastructure at Scale

People Data Labs is a B2B data infrastructure provider that sells raw, structured professional and company data at scale to technical buyers who embed it inside their own applications. Its key capabilities include:

• Nearly 3 billion person records de-duplicated to 1.5 billion unique profiles with resume-level depth

• API-first architecture with SDKs in Python, JavaScript, Ruby, Go, and Rust and dual query syntax (Elasticsearch DSL and SQL)

• Identify API for fuzzy matching from partial inputs, returning up to 20 matching profiles ranked by match score

• Transparent pricing starting with a permanent free tier of 100 credits/month and a Pro plan at $100/month

• Data License Feeds for bulk delivery via AWS S3, Snowflake, GCP, or Azure

People Data Labs is the alternative for technical teams that want raw enrichment data at scale to power their own products.

Why Choose People Data Labs Over FullContact for Developer-First Data Infrastructure?

People Data Labs stands out in the following areas:

• Dataset Scale and Professional Depth

People Data Labs maintains 1.5 billion unique profiles compared to FullContact's 248 million U.S. consumer profiles. The dataset includes resume-level employment history, education records, skills, certifications, ONET codes, inferred salary, and normalized job title taxonomy.

FullContact understands consumers; People Data Labs is built for workforce intelligence. The Person Search API exposes 140+ filterable attributes, letting teams build candidate pools and audience segments by querying the full dataset.

• Raw Data Layer vs. SaaS Service

FullContact packages its Identity Graph into four SaaS products with proprietary matching logic and persistent PersonIDs. People Data Labs sells the raw data and gets out of your way.

Customers like Clay, Hire Ez, SeekOut, and S&P Global embed PDL as the data layer for their own products. PDL's Cleaner APIs even expose normalization logic as free utilities so customers can replicate PDL's internal data quality processes.

• Flexible Data Licensing for High-Volume Use Cases

People Data Labs offers bulk data delivery via AWS S3, Snowflake, GCP, or Azure with delta file updates. Enterprise customers can license entire datasets and run enrichment locally without per-query API billing. FullContact does not offer bulk data licensing and contractually requires that all FullContact Data must be deleted within 30 days of termination.

Source: People Data Labs with Snowflake

🏅 NOTE: We also evaluated Proxycurl and Coresignal. Proxycurl focuses on LinkedIn-specific real-time scraping and Coresignal specializes in workforce datasets for investment intelligence, but People Data Labs offers the broadest developer-first data infrastructure with flexible delivery options and identity resolution without bundling a full SaaS service.

People Data Labs Pricing

People Data Labs uses a credit-based, pay-per-match model:

• Free: 100 monthly credits, contact data returned as True/False flags (obfuscated), no credit card required

• Pro: Starting at $100/month minimum commitment, full field access, 1,000 free Person Search credits/month, per-credit costs decrease with volume

• Enterprise: Custom pricing with dedicated support, higher rate limits, and access to Data License Feeds

Autocomplete and Cleaner APIs are free. Unused credits carry over up to 100% of the next period's allocation.

Source: People Data Labs Plans

Who Should Use People Data Labs?

Choose People Data Labs if:

• You are building a data-driven product (AI recruiting platform, CRM enrichment engine, investment research dashboard) and need raw professional data at scale as a core dependency.

• You need flexible data delivery including bulk licensing for high-volume use cases where per-call API pricing becomes prohibitive.

• You want transparent, self-serve pricing with a permanent free tier for testing, rather than entering an enterprise sales cycle for every evaluation.

7. FullEnrich — Best Alternative for Multi-Source Waterfall Enrichment Without Geographic Limits

FullEnrich is a waterfall enrichment platform that aggregates contact data from 20+ vendors under a single subscription, querying each source sequentially until it finds verified data. Its key capabilities include:

• Waterfall enrichment across 20+ data providers with sequential querying until verified matches are found

• Triple email verification using three independent verification services, achieving sub-1% bounce rates

• Mobile-first phone validation with US/Canada telecom partnerships for owner name-matching, removing up to 29% of bad numbers

• Global coverage with published find rates: US/Canada phone at 86% and email at 89%, EMEA phone at 71% and email at 84%, LATAM phone at 67% and email at 78%, APAC phone at 66% and email at 78%

• Credit-based pricing starting at $29/month for 500 credits with unlimited team seats

FullEnrich fills the gap FullContact leaves for teams needing global enrichment with transparent pricing and the ability to query multiple vendor databases rather than relying on a single source.

Why Choose FullEnrich Over FullContact for Multi-Source Enrichment?

FullEnrich stands out in the following areas:

• Waterfall Enrichment Eliminates Single-Database Coverage Limits

When FullContact's graph doesn't contain a contact, enrichment fails. FullEnrich queries 20+ vendors sequentially; because provider databases rarely overlap much, a contact missing from one is often present in another. Find rates exceed 80% for both emails and phone numbers, higher than single-source vendors typically achieve. Invalid results consume zero credits.

• Global Coverage by Design vs. US-Only Limitation

FullContact does not do business with companies looking for identity resolution outside of the United States. FullEnrich was built for global prospecting from day one, with geographic provider selection that routes requests to vendors with regional expertise (ContactOut for the UK, Datagma for France).

• Mobile-First Phone Validation

FullEnrich classifies each number as mobile, landline, or VOIP. For US/Canada numbers, it matches the phone line owner's name against the lead's name, removing up to 29% of bad numbers before delivery. Landlines are returned free. FullContact returns phone numbers as attributes, but mobile vs. landline classification and owner name-matching are not documented capabilities.

• Transparent Self-Serve Pricing

FullEnrich publishes pricing openly: Starter at $29/month for 500 credits, Pro at $55/month for 1,000 credits. The credit model is straightforward: 1 credit per work email, 3 per personal email, 10 per mobile phone, 0 for landlines and invalid data. FullContact's Resolve, Enrich, and Identity Streme have no public pricing.

🏅 NOTE: We also evaluated Apollo and Lusha for multi-source enrichment. Apollo combines prospecting and enrichment in a single database and Lusha is known for its Chrome extension, but FullEnrich offers the most effective multi-source enrichment for teams needing global coverage and verified contact data without single-database limitations.

Who Should Use FullEnrich?

Choose FullEnrich if:

• Your team has exhausted your primary enrichment tool and 20-40% of your prospect list still lacks contact data; FullEnrich's waterfall queries 20+ vendors to recover missed contacts.

• You run outbound campaigns into multiple geographies and need consistent enrichment coverage regardless of region, rather than accepting US-only limitations.

• You need verified mobile phone numbers for cold-calling with landline filtering and owner verification (US/Canada).

• You want transparent, self-serve pricing where you only pay for verified data.

The Final Verdict

FullContact works well as a privacy-safe identity resolution platform for US enterprises, but growing businesses often need broader capabilities across data coverage, activation, geographic reach, and pricing accessibility. Based on our research, here are the best alternatives:

• ZoomInfo for B2B data, the AI-powered GTM Context Graph, and intelligence access through APIs, MCP, GTM Workspace, and GTM Studio

• Cognism for European and global outbound prospecting with phone-verified mobile numbers and GDPR compliance across 15 markets

• Clearbit (Breeze Intelligence) for HubSpot-native enrichment, form shortening, and visitor identification without API integration

• Apollo.io for combined enrichment and multichannel sales engagement in a single self-serve platform

• Lusha for self-serve contact data via Chrome extension with transparent pricing and a permanent free plan

• People Data Labs for developer-first data infrastructure at scale with flexible licensing

• FullEnrich for multi-source waterfall enrichment that extends global coverage across 20+ data vendors

You don't have to choose between FullContact and these alternatives. Many businesses layer specialized tools on top of their existing identity resolution infrastructure. Consider your specific needs, geographic requirements, and growth plans when deciding which solution fits.
