FullEnrich Review 2026: Is This Waterfall Enrichment Platform Right for You?

FullEnrich does one thing in B2B data enrichment: it queries 20+ data vendors in sequence until it finds a verified email or phone number for your prospect. The logic is simple. No single data provider covers everyone. By waterfalling across multiple sources, FullEnrich claims 80%+ find rates where individual vendors cap out at 40–60%.

After analyzing the platform, we believe FullEnrich is the right choice if:

• You already have named prospect lists and need to fill in missing emails and phone numbers

• You're hitting coverage gaps with your current single-source data provider

• You sell into multiple regions (EMEA, LATAM, APAC) where US-centric tools fall short

• You want a simple, credit-based pricing model with no per-seat fees

• You use Clay, Make, Zapier, or n8n and need an enrichment step in your automation pipeline

However, FullEnrich is not a good choice if:

• You need intent data, technographics, or buying signals alongside contact data

• You want a full sales execution platform (sequences, dialer, deal management, CRM)

• You need CRM integrations beyond HubSpot today

• You require AI-powered account intelligence or conversation analysis

• You want a single platform that handles prospecting, outreach, and pipeline management

In that case, consider ZoomInfo: an all-in-one AI GTM Platform built on 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business emails. Beyond contact data, ZoomInfo's GTM Context Graph combines your CRM records, conversation transcripts, and behavioral signals with its B2B intelligence to show not just who to contact, but why and when. Your team can access this intelligence through the GTM Workspace for sellers, GTM Studio for marketers and RevOps, or APIs and MCP in any front-end.

We've included an overview of ZoomInfo at the end of this FullEnrich review for teams that need more than contact enrichment. To explore ZoomInfo's full platform, you can start a free trial here.

What is FullEnrich?

FullEnrich is a B2B waterfall enrichment platform founded in 2023 by Benjamin Douablin (CEO) and Grégoire Démogé (CPO) in San Francisco. The company's thesis: data enrichment is broken at a global scale because businesses rely on single providers with incomplete, regionally limited databases.

Rather than building its own contact database, FullEnrich queries 20+ data vendors in real time through a sequential waterfall. When one provider returns an invalid result, the system moves to the next until it finds a verified match. Because FullEnrich doesn't store contact data (it fetches fresh results from provider APIs each time), it reduces GDPR exposure.

The company grew bootstrapped to 7-figure ARR in about one year with five people before raising a $2M seed round in February 2025 led by Flex Capital. In February 2026, the company launched FullEnrich Search, adding built-in prospect discovery and repositioning from a pure enrichment tool into what it calls a "complete end-to-end outbound data engine."

FullEnrich targets SDR teams running cold outreach, GTM engineers building automated pipelines, growth agencies enriching client lists, and recruiters sourcing passive candidates. Users access the platform through CSV uploads, a LinkedIn Sales Navigator extension, API access, and integrations with Clay, Zapier, Make, and n8n.

FullEnrich Pros & Cons

FullEnrich Review: How it Works & Key Features

Waterfall Enrichment: FullEnrich queries 20+ vendors sequentially to find emails and phone numbers no single source can deliver.

The waterfall is FullEnrich's core product. Given a contact record with a first name, last name, and company name (or LinkedIn URL), FullEnrich queries its pool of 20+ data providers one by one. When a provider returns an invalid result, the waterfall continues until it finds a valid match. Invalid results consume zero credits.

The workflow is straightforward. Upload a CSV or XLSX file, map your columns to FullEnrich's fields, select what you want (work email, phone, personal email, or a combination), and click "Start Enrichment." Processing takes 1–2 minutes per contact for emails and 40–80 seconds for phone numbers, with up to 100 contacts processed simultaneously. You get an email notification on completion.

Including a LinkedIn URL improves match accuracy by up to 35%. Contacts enriched within the previous three months are automatically deduplicated on re-enrichment, so you don't burn credits on the same person twice.

The coverage argument is math. FullEnrich's blog frames it this way: if 40% of your leads lack contact data from a single provider, you need 250 names to actually reach 100 prospects. The waterfall approach can increase reachable contacts by 78% by recovering people any one vendor would miss.

Email Verification: Triple verification keeps bounce rates below 1% on validated addresses.

Every email FullEnrich returns runs through three verifiers plus a proprietary provider score. The system removes up to 32% of bad emails returned by providers before they reach the customer. Emails that fail verification don't consume credits, and the waterfall keeps searching.

Source: FullEnrich

FullEnrich classifies emails into four statuses: Valid (about 2% bounce rate), Probably Valid (about 9% bounce), Catch-All (about 26% bounce), and Invalid (no charge). The "Probably Valid" tier catches emails from catch-all domains that show positive signals across real-time online presence checks across hundreds of sites.

The catch-all category deserves attention. Catch-all domains accept all incoming email regardless of whether the specific address exists, making verification harder. FullEnrich's roughly 26% bounce rate on catch-all addresses means one in four of those emails won't land. Teams running high-volume outreach should factor this into their sending strategy and may want to filter catch-all addresses depending on their tolerance for bounces.

Phone Verification: Mobile-first approach with identity matching in the US and Canada.

FullEnrich takes a mobile-first approach: only mobile numbers consume credits. Landlines are returned free. For the US and Canada, FullEnrich uses telecom partnerships to classify numbers as mobile, landline, or VOIP and an AI system that matches the phone line owner's name against the lead's name to verify ownership. This system reportedly removes up to 29% of bad phone numbers.

Source: FullEnrich

Outside North America, verification is thinner. Mobile-type detection covers 40+ countries via number format analysis, but the identity-matching layer (confirming the phone belongs to the named person) is limited to US and Canada. Teams calling into EMEA or APAC should expect lower confidence on phone data.

At 10 credits per mobile phone versus 1 credit for a work email, phone-heavy teams will exhaust credits fast. A team enriching 100 contacts for both email and phone would spend about 1,100 credits, consuming a Pro plan's monthly allotment in a single batch.

FullEnrich Search: Built-in prospect discovery launched February 2026.

Search lets users build prospect lists inside FullEnrich using 15+ filters including job title, industry, location, and seniority. Previously, FullEnrich required you to bring your own lists. Search removes that dependency.

Source: FullEnrich

The feature claims 95% account coverage, meaning it surfaces nearly all employees at a target company. Unenriched contact exports from Search cost 0.25 credits, and the feature is included in all plans.

Search is available via both the web interface and a synchronous Search API. This positions FullEnrich as a direct competitor to database-first tools at the top of the funnel, though the feature is new and the filter set is narrower than established prospecting platforms.

Integrations: Automation-first, CRM-second.

FullEnrich's strongest integrations are with automation tools: Zapier, Make, n8n, and Clay are all live. The API supports enrichment via webhooks or polling, with a rate limit of 60 API calls per minute and up to 100 contacts per bulk call.

For CRM connectivity, only HubSpot has a native integration, and it supports only one-way push from FullEnrich to HubSpot. Salesforce, Pipedrive, and Zendesk are all listed as "Coming Soon" with early-access waitlists. Outreach tools (Smartlead, Salesloft, Outreach, Gong) are also "Coming Soon."

Source: FullEnrich

Teams running Salesforce-centric workflows will need to bridge via Zapier or Make until native integration ships. This is a real gap for mid-market and enterprise teams where Salesforce is the system of record.

Pricing: Credit-based with no per-seat fees.

FullEnrich uses a credit-based model with unlimited seats on every plan:

Credits are consumed only when data is found: 1 credit per work email, 3 per personal email, 10 per mobile phone. Person and company data (name, job title, company details) comes free with any enrichment. Credits roll over 3 months on monthly plans and 12 months on annual plans.

New accounts receive 50 free credits with no credit card required. There's no ongoing free tier; once credits are spent, enrichment stops until you subscribe.

The pricing page claims $641 in individual vendor subscriptions versus $29 via FullEnrich. That comparison assumes you'd need subscriptions to all 20+ vendors separately, which most teams wouldn't. But the consolidation benefit is real for teams paying for two or three data providers and still hitting coverage gaps.

Where FullEnrich Falls Short

FullEnrich finds contact data. That focus creates clear limitations for teams that need more.

Contact Data Only, No Intelligence Layer. FullEnrich's output is contact-centric: email, phone, job title, work history, and basic company information. It does not provide intent signals, technographic data, buying committee mapping, conversation intelligence, or funding and news triggers. Teams that need to know not just how to reach a prospect but whether that prospect is actively researching solutions need separate tools.

CRM Integration Gaps. With only HubSpot live (one-way push) and Salesforce, Pipedrive, and Zendesk all listed as "Coming Soon", teams using Salesforce as their system of record must rely on Zapier or Make as intermediaries. For enterprise RevOps workflows where enrichment needs to trigger routing, scoring, and CRM updates in real time, this adds friction.

Requires an Identifying Input. FullEnrich cannot find contacts based solely on company name and job title. You need a first and last name, a LinkedIn URL, or an email address to start. The February 2026 Search feature partially addresses this at the top of the funnel, but the core enrichment API still requires a known identifier.

Phone Verification Is Geographically Limited. The identity-matching verification that confirms a phone number belongs to a specific person is limited to the US and Canada. For teams running call campaigns into Europe or Asia-Pacific, phone numbers come with lower confidence. At 10 credits per phone, this creates an unfavorable cost-to-confidence ratio outside North America.

No Outreach or Execution Tools. FullEnrich is the data layer, not the engagement layer. There's no email sequencing, no dialer, no deal management, no pipeline tracking. Every enriched contact must be exported to another tool for action. For teams looking to consolidate their stack rather than add another point solution, this matters.

Young Platform With a Growing Feature Set. Founded in 2023 with roughly 50 employees and a $2M seed round, FullEnrich ships features fast but incrementally. Several announced integrations remain on waitlists. Teams evaluating FullEnrich should confirm that the features they need are live today, not listed as "Coming Soon."

These limitations reflect design choices, not oversights. The platform is built for teams that already have their GTM stack assembled and need a dedicated enrichment layer. But for organizations that want their data platform to also inform strategy, prioritize accounts, and drive execution, FullEnrich leaves significant gaps.

For Teams That Need More Than Enrichment: ZoomInfo

As an all-in-one AI GTM Platform, ZoomInfo fills FullEnrich's scope gaps by providing the full go-to-market infrastructure: not just contact data, but the intelligence, automation, and execution tools to act on it.

The B2B Data Platform: ZoomInfo's data spans identity, company context, and buying signals at scale.

Where FullEnrich aggregates third-party vendors to find contact information, ZoomInfo maintains its own verified database: 500M+ contacts, 100M+ companies, 135M+ verified phone numbers, 120M+ direct-dial phone numbers, and 200M+ verified business emails. This data runs through a multi-source verification pipeline backed by 300+ human researchers with up to 95% accuracy on first-party data.

The difference is dimensionality. ZoomInfo's data extends beyond contact details to include company context for 100M companies, technographics tracking 30,000+ technologies across 200+ categories, department org charts with decision-makers' direct dials, and buyer intent signals tracked from 210 million IP-to-Organization pairings. This means knowing whether a company is actively researching solutions, what technology they use, and where each contact sits in the buying committee.

The data quality has external validation. In a Fortune 500 competitive RFP analyzing 25 million contacts across vendors, the independent consultant concluded that "no other competitor came even close." ZoomInfo holds 133 No. 1 rankings on G2 and is named a Leader in the Gartner Magic Quadrant for ABM Platforms and a Leader in the Forrester Wave for Intent Data Providers.

The GTM Context Graph: ZoomInfo's intelligence layer captures not just what happened in a deal, but why.

Contact data tells you how to reach someone. The GTM Context Graph tells you why you should reach them now. By combining ZoomInfo's B2B data with a customer's CRM records, conversation transcripts, email threads, and behavioral signals, the GTM Context Graph processes 1.5B+ data points daily to extract the connections between signals and outcomes.

In practice, this means the system can identify that executive sponsorship entering at a particular deal stage, combined with ROI-focused questions on the last call and third-party signals showing the company is hiring and researching competitors, matches the pattern behind closed-won deals in your segment. That intelligence feeds into prioritized account recommendations, AI-drafted outreach that addresses specific concerns, and forecasts weighted by buying evidence rather than stage labels.

This depth of context exists because ZoomInfo spent two decades building data unification infrastructure, then extended it to first-party data through Chorus (conversation intelligence) and behavioral signal capture. No single enrichment tool can replicate this because it requires both the data scale and the context extraction engines built on top of it.

Universal Access: Use ZoomInfo's intelligence in any tool, any workflow, any AI agent.

ZoomInfo delivers its intelligence through three channels:

GTM Workspace gives sellers a single screen where prioritized accounts, AI-drafted outreach, and deal execution converge. AI agents handle account research, outreach drafting, CRM updates, and signal monitoring. Customer results include Seismic's 54% productivity boost and 11.5 hours saved per week per seller.

GTM Studio gives marketers, RevOps, and GTM engineers a builder environment where audience definition, campaign orchestration, and pipeline measurement happen through natural language. It includes built-in waterfall enrichment from 25+ data sources at no additional cost, pre-built GTM plays, and multi-channel orchestration across email, calls, ads, and direct mail.

APIs and MCP expose the same intelligence to any custom agent, internal tool, or partner platform. The MCP server connects AI models directly to ZoomInfo's data as a native tool, currently supporting Claude and ChatGPT. API access is included in all relevant plans.

All three channels draw from the same GTM Context Graph: the same data, the same intelligence. Where you work never limits the quality of information available.

Pricing: Custom-quoted, with a permanent free tier.

ZoomInfo uses a custom-quoted, seat-and-credit-based subscription model. Pricing depends on users, credit volume, features, and contract length. Unlike FullEnrich's published prices, ZoomInfo requires a conversation with sales.

For teams not ready to commit, ZoomInfo Lite is a permanent free tier (not a trial) that includes access to 100M+ verified profiles, 10 monthly export credits, the ReachOut Chrome Extension, WebSights Lite (up to 10 website visitor reveals per day), HubSpot integration, and built-in email sending. A 7-day free trial with broader access is also available.

FullEnrich or ZoomInfo: Comparison Summary

Final Verdict

The choice between FullEnrich and ZoomInfo depends on what role data plays in your go-to-market motion.

Choose FullEnrich if you have your GTM stack assembled and need a dedicated layer to fill contact data gaps. It works well for teams that run outbound through separate tools (a CRM here, a sequencer there, an enrichment step in between) and want the highest possible find rates for emails and phones without committing to a larger platform. Credit-based pricing with no seat fees makes it accessible for small teams and agencies enriching lists on behalf of clients. If your problem is "I have 500 prospects and only 60% have emails," FullEnrich solves that efficiently.

Choose ZoomInfo if you need your data platform to do more than fill in blanks. ZoomInfo serves teams that want to know not just how to reach a prospect, but whether that prospect is actively in-market, what technology they use, who else is on the buying committee, and what patterns from thousands of similar deals suggest about the next best action. With the GTM Context Graph powering AI-driven execution through GTM Workspace, GTM Studio, and open APIs and MCP access, ZoomInfo is the platform for teams ready to consolidate their GTM stack around one intelligence layer rather than assembling it from point solutions.

FullEnrich solves a real problem: no single data vendor covers everyone, and waterfalling across providers recovers contacts you'd otherwise miss. For teams whose needs stop at enrichment, that's enough. For teams whose needs extend into intelligence, execution, and strategy, the question is whether finding the contact is the hard part, or whether knowing what to do once you find them is what actually drives revenue.
