7 FullEnrich Alternatives: Specialized Tools for B2B Contact Data and GTM Intelligence (2026)

FullEnrich has built a solid waterfall enrichment platform, querying 20+ data vendors sequentially to find verified emails and phone numbers that no single provider can match. With an 80%+ find rate and sub-1% bounce rate on valid emails, it solves a real problem: the coverage gap that costs outbound teams up to 40% of their pipeline.

But as your go-to-market strategy matures, you may find that enrichment alone is only one piece of the puzzle. FullEnrich finds contact data for prospects you already know about.

While it recently launched a Search feature (February 2026), the platform does not provide buying intent signals, technographic intelligence, AI-powered outreach, CRM deal management, or the contextual reasoning that tells your team why a prospect is worth pursuing right now.

That's where this guide comes in. Whether you're looking to:

• Access a large B2B data platform with AI-powered intelligence that reveals not just who to contact, but why and when

• Build custom multi-provider enrichment workflows with AI research and outbound automation

• Start prospecting immediately with a free, all-in-one platform that includes sequences, a dialer, and CRM

• Get waterfall enrichment coverage at the lowest entry price

• Prospect into European markets with compliance-first, phone-verified contact data

• Enrich contacts instantly without leaving LinkedIn

• Discover entire buying committees from just a company domain, with built-in intent signals

We'll explore FullEnrich alternatives that excel in these specific areas.

Some teams might use these tools alongside FullEnrich to layer intelligence on top of enriched contact data. Others might replace FullEnrich entirely with a platform that covers enrichment as part of a broader workflow. This isn't about finding a "better" tool; it's about finding the right fit for how your team runs its go-to-market motion.

Let's look at the FullEnrich alternatives and find which ones belong in your GTM stack.

What is FullEnrich?

FullEnrich is the first "Waterfall Enrichment" platform for B2B contact data. It solves the coverage gap that no single data vendor can close alone. The platform aggregates contact data from 20+ vendors and queries them sequentially until a verified email or phone number is found, charging credits only when it locates data.

Its key features include:

• Waterfall enrichment across 20+ data providers for an 80%+ find rate

• Triple email verification that removes up to 32% of bad emails returned by providers, delivering a sub-1% bounce rate on valid emails

• Mobile-first phone validation with US/Canada telecom-backed identity verification and format detection for 40+ countries

• FullEnrich Search (February 2026) with 15+ filters and claimed 95% account coverage for building prospect lists directly inside the platform

• Credit-based pricing starting at $29/month for 500 credits with unlimited users and 3-month credit rollover on monthly plans

• Integrations with HubSpot, Zapier, Make, n8n, and Clay, plus a REST API for custom workflows

The platform's core value proposition is "20+ data sources for the price of 1": instead of maintaining multiple vendor contracts, separate billing, and complex API orchestration, teams get a single subscription, single API, and single credit system. FullEnrich does not maintain a proprietary contact database. It queries providers in real time, which keeps data fresh and reduces GDPR storage exposure.

For teams running high-volume outbound who need broad contact coverage, FullEnrich delivers. But its scope is narrow by design: it finds emails and phone numbers

It does not provide buying intent signals, technographic intelligence, AI-powered prospecting, conversation intelligence, deal management, or the contextual reasoning that tells your team which accounts to prioritize and why. That's why we've focused on alternatives that extend beyond enrichment into the broader GTM workflow.

Looking for a complete AI-powered GTM platform that goes beyond contact data? ZoomInfo combines B2B data with an intelligence layer that reveals why deals move. Learn more about ZoomInfo.

How We Curated Our List of FullEnrich Alternatives

After testing FullEnrich and researching the B2B contact data and GTM intelligence market, we found that teams searching for FullEnrich alternatives typically need capabilities beyond waterfall enrichment. While FullEnrich excels at finding contact data across multiple vendors, businesses often need:

• B2B intelligence that includes intent signals, technographics, org charts, and AI-powered account insights (not just emails and phones)

• Custom enrichment workflows with conditional logic, AI research agents, and outbound automation

• A free, all-in-one platform that combines prospecting, sequencing, and CRM from day one

• Waterfall enrichment at a lower entry price for budget-constrained teams

• European market prospecting with compliance-first, human-verified phone data and DNC screening

• Instant contact enrichment within LinkedIn, without CSV exports or batch processing

• Contact discovery at target companies from just a domain, layered with intent and technographic signals

Each tool on this list leads in one of these areas. You might use them alongside FullEnrich or switch entirely; it depends on what your GTM motion demands.

1. ZoomInfo — Best Alternative for Complete AI-Powered GTM Intelligence

ZoomInfo is an AI GTM Platform built on a large proprietary data foundation: 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business email addresses.

Where FullEnrich aggregates contact data from 20+ third-party vendors in real time, ZoomInfo owns and operates its own B2B data platform, then layers the GTM Context Graph on top (an intelligence layer that captures not just what happened in a deal, but why). Its key features include:

• Proprietary B2B data: 500M contacts, 100M companies, 135M+ verified phone numbers, 120M direct-dial phone numbers, and 200M+ verified business email addresses, verified by 300+ human researchers with up to 95% accuracy on first-party data

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

• Buyer Intent Data: 210 million IP-to-Organization pairings and 6 trillion+ new keyword-to-device pairings sourced monthly, with Guided Intent that identifies topics correlated with deal success

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

For teams that have outgrown standalone enrichment tools and need a platform where data, intelligence, and execution work together, ZoomInfo provides GTM infrastructure that FullEnrich's contact-focused architecture was never designed to deliver.

Why Choose ZoomInfo Over FullEnrich for GTM Intelligence

While FullEnrich excels at finding emails and phone numbers via waterfall enrichment, ZoomInfo provides the data, contextual intelligence, and execution infrastructure that power the entire go-to-market motion. Here's where ZoomInfo steps up:

Proprietary Data vs. Third-Party Aggregation

FullEnrich does not maintain a proprietary contact database. It queries third-party vendors in real time, so the quality and coverage of results depend entirely on those providers. Its enrichment output is contact-centric: email, phone, job title, work history, and company basics. It does not provide intent data, technographic signals, org charts, or company attribute depth beyond what providers return.

ZoomInfo owns and maintains its own B2B data. Beyond contact information, the platform provides 300+ company attributes for market segmentation, department org charts with decision-makers' direct dials, technographic profiles of 30+ million companies tracking 30,000+ technologies, and buyer intent signals that reveal when accounts are actively in-market.

Source: ZoomInfo Data

In a Fortune 500 competitive RFP analyzing 25 million contacts across vendors, the independent consultant concluded that "no other competitor came even close."

This breadth means your team doesn't just get a phone number. You get the full picture: who the decision-makers are, what technology they use, whether they're researching solutions like yours, how their org chart is structured, and which signals indicate they're ready to buy. FullEnrich answers "what is this person's email?" ZoomInfo answers "who should you talk to, why, and when?"

⚡ZoomInfo in Action: Your team identifies a target account. Instead of needing a name and LinkedIn URL to enrich (as FullEnrich requires), ZoomInfo's search surfaces the entire buying committee using org charts and department filters.

You see that three VPs were recently hired, the company shows intent signals on topics related to your solution, and they just adopted a competitor's technology. GTM Workspace drafts personalized outreach addressing the competitive displacement opportunity, and the sequence launches, all from one platform.

The GTM Context Graph: Intelligence Beyond Raw Data

FullEnrich delivers contact data. ZoomInfo delivers context. The GTM Context Graph fuses ZoomInfo's B2B data with your CRM records, conversation intelligence from calls and meetings (via Chorus), email interactions, and behavioral signals into an intelligence layer that processes 1.5B + data points daily.

Source: ZoomInfo Context Graph

As ZoomInfo's Chief Product Officer Dominik Facher writes: "The CRM recorded the state change. It has no record of why it happened." The GTM Context Graph captures that "why": the CFO joined the call and asked about ROI (that's what accelerated the deal), a champion went quiet for eight days during an internal budget battle (that's what nearly killed it).

This contextual reasoning flows into every downstream action, from AI-drafted outreach to deal prioritization to pipeline forecasting.

No enrichment tool, including FullEnrich, operates at this level. Enrichment tools find contact data. The GTM Context Graph reasons about your entire go-to-market motion.

Multiple Access Points: Use It Anywhere

FullEnrich's data is accessible via CSV upload, API, and integrations with HubSpot, Zapier, Make, n8n, and Clay. CRM integrations remain thin: Salesforce, Pipedrive, and Outreach are still "Coming Soon" as of early 2026.

ZoomInfo delivers its intelligence through three channels. GTM Workspace gives sellers a single interface where AI agents handle account research, outreach drafting, CRM updates, and signal monitoring. GTM Studio gives marketers and RevOps a builder environment where audience definition, campaign orchestration, and pipeline measurement happen in natural language.

APIs and MCP expose the same intelligence to any custom agent, internal tool, or partner platform, including Claude and ChatGPT.

Source: ZoomInfo API

Customer results reflect this breadth: Seismic's sales team boosted productivity by 54% and attributed 39% of pipeline to ZoomInfo signals. Snowflake achieved 200% higher conversion rates on top-scoring accounts. Thomson Reuters increased closed-won deals by 40%.

⚡ZoomInfo in Action: A marketer in GTM Studio describes an audience in plain language: "Mid-market SaaS companies showing intent on sales automation, using Salesforce, that grew headcount 20%+ last quarter."

Source: ZoomInfo GTM Studio

The platform builds the audience, enriches contacts, launches a multi-channel play targeting accounts matching your proven win patterns, and delivers hot accounts directly into sellers' GTM Workspace. The same intelligence flows into your custom AI agent via MCP. No CSV exports, no separate enrichment step, no tool-switching.

🏅 NOTE: We evaluated other B2B data and intelligence platforms and found ZoomInfo to be the leader for teams needing more than contact enrichment. ZoomInfo holds 133 No. 1 rankings on G2 across Sales Intelligence, Buyer Intent, Data Quality, and Account Data Management, was named a Leader in the Forrester Wave for Intent Data Providers (Q1 2025), and is a Leader in the Gartner Magic Quadrant for ABM Platforms (2024 & 2025).

No other platform on this list provides the same combination of proprietary data, contextual AI intelligence, and multiple access channels.

ZoomInfo Pricing

ZoomInfo uses a custom-quoted, seat-and-credit-based subscription model organized into three product lines:

Sales Plans (for revenue teams):

• Professional: Contact and company data with profiles, mobile numbers, business emails, CRM integrations, Chrome extension, and AI-powered email generation

ZoomInfo also offers ZoomInfo Lite, a permanent free tier with access to 100M+ verified profiles, 10 monthly export credits, individual and company searches, CRM enrichment, and the Chrome extension. A 7-day free trial is also available with no credit card required.

Who Should Use ZoomInfo?

Choose ZoomInfo if:

• You need more than contact data. Your GTM motion requires buyer intent signals, technographic intelligence, org charts, conversation intelligence, and AI-powered account insights, not just emails and phone numbers. ZoomInfo's three-pillar architecture (data + GTM Context Graph + multiple access channels) provides the intelligence layer that enrichment-only tools cannot.

• Your team spans sales, marketing, and RevOps, and you need one platform that serves all of them. GTM Workspace powers sellers, GTM Studio powers marketers and RevOps, and APIs/MCP power any custom tool or AI agent, all drawing from the same intelligence.

• You're building an AI-powered GTM stack and need infrastructure-grade data access. ZoomInfo's Enterprise API and MCP server deliver the GTM Context Graph into any application, workflow, or AI agent.

Ready to move beyond contact enrichment? ZoomInfo gives your team the data, intelligence, and execution platform to find, win, and grow customers. Start your free trial or request a demo to see how ZoomInfo can power your GTM motion.

2. Clay — Best Alternative for Custom Multi-Provider Enrichment Workflows

Clay is a GTM data enrichment and workflow automation platform that gives teams a spreadsheet-style interface to orchestrate enrichment across 150+ data providers, design custom waterfall logic with conditional branching, and automate outbound workflows. Its key capabilities include:

• 150+ data provider integrations including Apollo, Prospeo, ContactOut, People Data Labs, and Hunter, allowing teams to build custom waterfall sequences across any combination of sources

• AI-powered research agent (Claygent) that browses websites, reads pages, and returns structured insights at scale, with over 1 billion lifetime runs

• Custom waterfall logic with if/then branching using AI formulas expressed in plain English

• Native CRM sync with Salesforce and HubSpot, plus direct push to outreach tools and a native email sequencer

Why Choose Clay Over FullEnrich for Custom Enrichment Workflows?

Clay stands out in the following areas:

• Workflow Orchestration Beyond Contact Enrichment

FullEnrich enriches contacts: you provide a list, it finds verified emails and phones. Clay builds entire GTM workflows: teams use it to find companies, discover people, enrich across 150+ providers, score accounts, trigger on intent signals, conduct AI research, write personalized copy, and push to CRM or sequencers, all in one continuous workflow.

A FullEnrich user receives a CSV of enriched data; a Clay user receives a fully scored, researched, and sequenced prospect list with personalized messaging already drafted. Recharge drove a 20% jump in opportunity conversion and 10x call conversion improvement using this kind of multi-step workflow.

• Custom Waterfall Design vs. Pre-Built Waterfall Sequencing

FullEnrich operates a managed waterfall: the provider sequence is pre-configured, and users upload a CSV and receive results. Clay gives teams the raw materials to build their own waterfalls from scratch, selecting which providers to query, configuring conditional logic (e.g., use different providers for different geographies), and chaining providers in custom sequences.

The trade-off is simplicity vs. control: FullEnrich deploys faster, but Clay's custom builder lets teams design proprietary enrichment logic that competitors cannot replicate.

• AI Research That Extends Beyond Structured Data

FullEnrich returns structured fields: email, phone, job title, company basics. Claygent generates unstructured insights by browsing websites, extracting case study mentions, summarizing pain points from job postings, and answering custom research questions at scale.

This is a different category of enrichment: FullEnrich retrieves what exists in databases; Clay discovers what requires real-time AI research.

Source: Clay Claygent

🏅 NOTE: We also evaluated Apollo and Landbase for this archetype. While Apollo excels at integrated prospecting and sequencing within a single database, and Landbase offers strong EMEA coverage with AI-powered workflows, Clay offers the widest data access through 150+ provider integrations and the most workflow customization for teams needing to design proprietary enrichment logic.

Clay Pricing

Clay uses a dual-currency model where Actions measure platform orchestration and Data Credits purchase marketplace data. All plans include unlimited users.

• Free: $0/month with 500 actions/month and 100 data credits, 200 rows per table

• Launch: From $167/month (annual) with 15,000 actions/month and from 2,500 data credits

• Growth: From $446/month (annual) with 40,000 actions/month and from 6,000 data credits, adds CRM integrations and priority support

• Enterprise: Custom pricing with 200,000+ actions/month, SSO, RBAC, and data warehouse sync

Who Should Use Clay?

Choose Clay if:

• Your team has a dedicated GTM Engineer or RevOps professional who can build and maintain custom enrichment workflows, and you need orchestration that extends beyond contact enrichment into AI-powered research, intent monitoring, and multi-step outbound automation.

• Your enrichment logic requires custom conditional branching and geography-based provider routing that a fixed waterfall cannot replicate.

• You want to layer unstructured AI research on top of structured contact data, creating enrichment depth that no single contact database can provide.

3. Apollo.io — Best Alternative for Free-to-Start All-in-One Prospecting

Apollo.io is a B2B sales intelligence and engagement platform that combines contact data, multichannel outreach sequences, a built-in dialer, and CRM capabilities in a single tool. Unlike FullEnrich's enrichment-only focus, Apollo maintains its own database of 270M+ contacts and 70M companies and layers sales engagement directly on top. Its key capabilities include:

• Free-forever Starter plan with 75 credits per month, unlimited email credits on corporate domains, access to the full 270M+ database, email sequences, and a built-in CRM

• All-in-one prospecting and engagement that consolidates data provider, enrichment, outreach platform, dialer, and CRM into one login

• Buying intent data covering over 1,600 topics with a 98% accuracy rate via a LeadSift (Foundry) partnership

• Multichannel sequences supporting email, phone, LinkedIn steps, and custom tasks, with A/B testing and AI-assisted sequence building

Why Choose Apollo.io Over FullEnrich for All-in-One Prospecting?

Apollo.io stands out in the following areas:

• Prospecting, Enrichment, and Engagement in One Workflow

FullEnrich sits downstream of list building: you must source your prospect list elsewhere before enriching it. Apollo starts at the top of the funnel. Teams build lists using 65+ data attribute filters, enrich inline, load into sequences, call via the built-in Parallel Dialer, and track deals in pipeline boards.

Source: Apollo.AI Dialer

For teams juggling multiple vendor contracts across data, enrichment, engagement, and CRM, Apollo's consolidation removes both cost and operational complexity.

• Free-Forever Adoption Without Procurement

Apollo's free Starter plan lets individual SDRs and founders sign up, build lists, launch sequences, and book meetings at zero cost. FullEnrich offers 50 free credits on signup as a trial allowance, then requires a $29/month minimum subscription.

For budget-constrained individuals, the difference between "free forever with real functionality" and "free trial then monthly commitment" creates real adoption friction.

• Proprietary Database Supports Prospecting from Zero

FullEnrich requires an identifying input: first name + last name + company, and/or a LinkedIn profile URL. Apollo's 270M+ contacts are searchable via 65+ filters from scratch. A rep can define their ICP and build a targeted list without needing any prior lead data.

🏅 NOTE: We also evaluated Kaspr and Snov.io. While Kaspr excels at real-time LinkedIn prospecting with a Chrome extension and GDPR-compliant European data, and Snov.io offers affordable email finding with built-in drip campaigns, Apollo.io offers the most full-featured free-to-start experience for teams needing all-in-one prospecting, enrichment, sequencing, and pipeline management.

Apollo.io Pricing

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

• Free (Starter): $0 forever, 75 credits/month, unlimited email credits on corporate domains, 2 active sequences, built-in CRM

• Basic: $49/seat/month (annual), 2,500 credits/month, multiple seats, Microsoft Office support

• Professional: $79/seat/month (annual), 4,000 credits/month, data enrichment access, unlimited sequences

• Organization: $119/seat/month (annual only, minimum 3 seats), 72,000 credits/year, SSO, custom reporting

Who Should Use Apollo.io?

Choose Apollo.io if:

• You want to start prospecting immediately without paying anything, using a free plan that includes database access, email sequences, a CRM, and the Chrome Extension.

• You need prospecting, enrichment, and engagement in a single platform, eliminating the multi-vendor stack of data provider + enrichment tool + engagement platform + dialer.

• Your team values product-led adoption and ease of setup over the highest contact data find rates that FullEnrich's 20-provider waterfall delivers.

4. BetterContact — Best Alternative for Budget-Conscious Waterfall Enrichment

BetterContact is a waterfall enrichment platform that aggregates contact data from 20+ vendors starting at $15/month, making it the most affordable dedicated waterfall tool available. Its key capabilities include:

• Waterfall enrichment across 20+ providers delivering 87-95% email enrichment rates

• Pay-only-for-valid-results credit model where no credits are charged for invalid data or failed lookups

• Catch-all email verification included at no extra cost on Pro plans

• Bring-your-own API keys option on Enterprise tier for teams with existing vendor subscriptions

• Agency discounts of 15-30% starting at 5,000 credits/month

Why Choose BetterContact Over FullEnrich for Budget-Conscious Waterfall Enrichment?

BetterContact stands out in the following areas:

• 48% Lower Entry Price for Small Teams

BetterContact's Starter plan costs $15/month for 200 credits, compared to FullEnrich's $29/month for 500 credits. While FullEnrich delivers more credits per dollar, the absolute price threshold matters for three-person agencies and solo founders where every monthly commitment requires justification.

Teams that validate waterfall enrichment at $15 can graduate to BetterContact's Pro plan at $49/month for 1,000 credits, still cheaper than FullEnrich's $55/month Pro for the same credit count.

• Bring-Your-Own API Keys Reduces Costs for Teams With Existing Vendor Relationships

BetterContact's Enterprise plan lets customers plug in their own API keys from data providers they already subscribe to. If you already pay for Apollo or RocketReach, you can route those providers through your own keys and only consume BetterContact credits when the waterfall cascades to providers you don't already use.

Source: BetterContact API

FullEnrich does not offer this option, so every enrichment consumes FullEnrich credits regardless of existing vendor contracts.

• Agency-Specific Infrastructure for High-Volume Outbound

72% of BetterContact users are outbound agencies, and the product reflects this: agency discounts, monthly commitment flexibility, credit rollover, and a whitelabel API for embedding enrichment into client-facing dashboards. Customers report >80% valid enrichment increase and $4.5K monthly savings on invalid data.

🏅 NOTE: We also evaluated Dropcontact and Snov.io. While Dropcontact excels at real-time email verification and GDPR compliance for European teams, and Snov.io offers an all-in-one sales automation suite with email finding, BetterContact delivers the closest feature parity to FullEnrich's waterfall coverage at the lowest entry point.

BetterContact Pricing

BetterContact operates on a usage-based credit system where 1 verified email = 1 credit and 1 verified mobile = 10 credits:

• Starter: $15/month for 200 credits, waterfall enrichment, API, HubSpot and Google Sheets integrations

• Pro: $49/month for 1,000 credits, adds Clay and Zapier integrations, catch-all verification, mobile phone verification

• Enterprise: From $799/month with custom credits, dedicated account manager, bring-your-own API keys, and agency discounts

All plans include 50 free credits on signup to test before committing.

Who Should Use BetterContact?

Choose BetterContact if:

• You're a small agency, bootstrapped startup, or solo founder testing waterfall enrichment for the first time and need to prove ROI before committing larger budgets.

• Your team already subscribes to Apollo, Lusha, or RocketReach and wants to add waterfall enrichment without paying twice for the same data, using the bring-your-own API keys option.

• You operate a high-volume outbound agency and need monthly commitment flexibility, transparent per-valid-contact pricing, and agency discounts.

5. Cognism — Best Alternative for EMEA-Focused Compliance-First Prospecting

Cognism is a B2B sales intelligence platform built for revenue teams that need accurate, compliant contact data for European market prospecting. The platform leads with the message "Accurate and compliant sales data for US business scaling into Europe". Its key capabilities include:

• Diamond Phone-Verified Data with 87% accuracy and 3x higher connect rates through human verification calls confirming the correct person answers

• DNC compliance screening across 15+ countries including UK TPS/CTPS, Germany, France, Spain, and more

• 200M+ European contacts with 90% coverage of director-level contacts in Europe

• Bombora intent data across 11,000+ topics embedded directly in the platform

Why Choose Cognism Over FullEnrich for EMEA-Focused Prospecting?

Cognism stands out in the following areas:

• Diamond Data Phone Verification Delivers Confidence Waterfall Aggregation Cannot

FullEnrich's phone verification (AI name-matching + telecom partnerships) is limited to the US and Canada. EMEA phone numbers come back at lower confidence tiers without identity verification.

Cognism's Diamond Data phone numbers are verified by Cognism's team through calls confirming the right person answers, delivering 87% accuracy and a 20% connection rate, 7x the industry standard. The platform also offers Diamonds on Demand, verifying a specific contact's number within 48 hours on request.

• Compliance Embedded in the Data Layer, Not Delegated to Upstream Providers

FullEnrich queries 20+ vendors in real time but has no DNC screening layer of its own. Cognism screens every contact against DNC registries in 15+ countries as standard, holds ISO 27001, ISO 27701, and SOC 2 Type II certifications, and operates a fully notified database within GDPR timeframes.

Source: Cognism Security

For regulated industries where violations carry six- and seven-figure fines, this compliance infrastructure is a procurement requirement.

• European Data Depth That Doesn't Degrade Outside North America

FullEnrich's own data shows the coverage drop: phone enrichment falls from 86% in US/Canada to 71% in EMEA. Cognism was founded in London with European coverage as the founding thesis. Lead Forensics cited that Cognism's European data "far outperformed" a US-based competitor, converting 60% better.

🏅 NOTE: We also evaluated Lusha for this archetype. While Lusha offers a freemium entry point and self-serve workflows, Cognism provides the strongest compliance-first European data with human-verified phones and built-in DNC screening across 15+ countries.

Cognism Pricing

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

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

• Elevate: Adds Diamond Phone-Verified Data, up to 10 lists with 500 contacts per list, and market signals including job changes, funding alerts, hiring data, M&A, intent data across 12 topics, and technographic data

A free data sample matching your ICP is available for accuracy evaluation.

Who Should Use Cognism?

Choose Cognism if:

• Your outbound targets European markets and you need verified mobile numbers with regional data depth that doesn't degrade outside North America.

• Your team runs phone-heavy campaigns and cannot afford wrong numbers or unverified contacts; Cognism's human-verified Diamond Data solves the confidence gap that FullEnrich's US/Canada-only phone verification leaves for European prospects.

• You operate in a regulated industry where GDPR/DNC compliance is a procurement requirement, not a feature preference.

6. Kaspr — Best Alternative for LinkedIn-Native Prospecting Workflows

Kaspr is a B2B contact data platform that surfaces verified phone numbers and email addresses directly within LinkedIn's interface. Founded in Paris in 2018 and acquired by Cognism in 2022, Kaspr targets SMBs and individual contributors whose prospecting workflow lives on LinkedIn. Its key capabilities include:

• Chrome Extension that displays verified contact data on LinkedIn profiles, search results, groups, and events without leaving the browser

• Unlimited B2B emails on all paid plans (fair-use cap of 10,000 per month)

• 500M+ contact database with 200M+ European B2B decision-maker contacts

• Bulk enrichment from LinkedIn lists with up to 2,500 contacts per search on Sales Navigator

Why Choose Kaspr Over FullEnrich for LinkedIn-Native Prospecting?

Kaspr stands out in the following areas:

• Native LinkedIn Integration Eliminates Export-Enrich-Import Loops

FullEnrich requires CSV uploads or API calls with processing times of 1-2 minutes per contact for emails. Kaspr's Chrome Extension reveals phone numbers and emails with a single click directly within LinkedIn. For SDRs whose prospecting begins and ends on LinkedIn, this saves real time: one customer reported booking six discovery calls within two weeks because of faster data access.

Source: Kaspr in Linkedin

• Unlimited B2B Emails Removes Volume Anxiety

FullEnrich charges 1 credit per work email, meaning a team on the $29/month Starter exhausts credits after 500 emails. Kaspr offers unlimited B2B emails on all paid plans, reserving credit-based metering for phone numbers only. For email-first outbound teams, this pricing model costs less.

• European Data Depth and GDPR-Native Compliance

Built in France with 200M+ European contacts and infrastructure hosted on OVH France. Customer testimonials highlight stronger European mobile coverage: one user switching from a prior tool noted that it would "pull American numbers when it was a UK-based person", a problem Kaspr resolved.

🏅 NOTE: We also evaluated Hunter and Lusha. While Hunter excels at domain-based email pattern discovery, and Lusha offers a similarly LinkedIn-native Chrome Extension, Kaspr's unlimited B2B email model and European data depth (backed by Cognism's infrastructure) position it as the specialist for LinkedIn-first prospecting.

Kaspr Pricing

Kaspr uses a credit-based, per-seat model with unlimited B2B emails on all paid plans:

• Free: $0 permanently, 15 B2B emails/month (unlimited if you invite 3 colleagues), 5 phone credits, no credit card required

• Starter: $49/user/month (annual), unlimited B2B emails, 1,200 phone credits/year, Sales Navigator support

• Business: $79/user/month (annual), unlimited B2B emails, 2,400 phone credits/year, Recruiter Lite support, unlimited lead lists

• Organization: Custom pricing, minimum 5 users, 24,000 phone credits/year, dedicated account manager

Who Should Use Kaspr?

Choose Kaspr if:

• Your prospecting workflow lives on LinkedIn, Sales Navigator, or Recruiter Lite, and you want contact data to appear directly within the platform without switching tools.

• You run high-volume email campaigns and need unlimited email enrichment without per-credit costs, reserving phone credits for high-priority accounts only.

• Your primary market is Europe and you've experienced coverage gaps with US-centric providers; Kaspr's 200M+ European contacts and French-origin infrastructure deliver stronger mobile coverage in EU markets.

7. Prospeo — Best Alternative for Single-Database Prospecting with Domain Discovery

Prospeo is a B2B contact data and lead intelligence platform that operates a proprietary database of 300M+ professional profiles with 143M verified emails and 125M verified mobile numbers, all verified through a 5-step process delivering 98% claimed accuracy. Its key capabilities include:

• Domain Search that retrieves all contacts at a company from just a domain name, without needing individual identifiers

• 300M+ profiles refreshed on a 7-day cycle for current data

• Bombora-powered intent signals covering 15,000 topics layered with technographic filters (4,946 technologies) and behavioral signals

• Free plan with 100 credits/month and paid plans from $37/month for 2,000 credits

Why Choose Prospeo Over FullEnrich for Domain-Level Prospecting?

Prospeo stands out in the following areas:

• Domain-Level Discovery Without Individual Identifiers

FullEnrich requires an identifying input: first name + last name + company, or LinkedIn URL. Prospeo's Domain Search lets you enter a company domain and retrieve all available contacts at that organization, no names required. For account-based prospecting where the goal is mapping an entire buying committee, this eliminates a whole step in the workflow.

Source: Prospeo Domain Search

• Single-Source Verification vs. Multi-Provider Aggregation

FullEnrich queries providers and then verifies results, removing up to 32% of bad emails that vendors return. Prospeo verifies before surfacing: only contacts passing all five verification checkpoints (triple verification, spam trap detection, honeypot filtering, catch-all analysis, and provider-risk filtering) enter the database.

If a contact is in Prospeo's database, you get a verified result immediately rather than waiting through a sequential waterfall.

• Intent Signals and Technographic Filters Built In

FullEnrich provides contact-centric enrichment without intent data, technographics, or company intelligence beyond what providers return. Prospeo bundles Bombora intent data across 15,000 topics, 4,946 detectable technologies, department headcount growth, job change triggers, and funding stage filters into the prospecting interface.

🏅 NOTE: We also evaluated Dropcontact and Salesforge. While Dropcontact excels at real-time email verification and GDPR compliance, and Salesforge offers AI-powered email sequencing, Prospeo provides the most direct single-database prospecting experience with domain-level discovery and built-in intent signals.

Prospeo Pricing

Who Should Use Prospeo?

Choose Prospeo if:

• Your prospecting starts at the account level: you have target companies and need to discover all relevant contacts without pre-built name lists. Prospeo's Domain Search addresses this directly; FullEnrich requires you to already know who you're enriching.

• You want intent signals, technographic filters, and contact data in a single platform, reducing tool sprawl by managing everything from prospect discovery to verified enrichment in one system.

• You prefer a single verified data source with a 7-day refresh cycle over the complexity of managing a 20-provider waterfall, and your ICP is well-covered by Prospeo's 300M+ profile database.

The Final Verdict

• ZoomInfo for teams that need a complete AI-powered GTM platform with B2B data, contextual intelligence, and access across sellers, marketers, and RevOps

• Clay for technically-inclined teams that want to build custom enrichment workflows with 150+ providers, AI research agents, and outbound automation
