# FullEnrich

> FullEnrich is a waterfall enrichment platform that queries more than twenty-five B2B data providers in sequence to find verified work emails, personal emails, and mobile phone numbers, charging one credit for a work email, three for a personal email, and ten for a mobile, and charging nothing when it cannot verify a result; it exposes enrichment, search, and reverse email lookup APIs plus an MCP server on all tiers, and starts at 55 dollars a month for 1,000 credits.

## Overview

FullEnrich came out of a familiar frustration. Jean-Luc Manceron, Gregoire Demoge, and Benjamin Douablin were scaling an earlier startup, Salesramp, and could not get acceptable contact coverage from any single data vendor. In 2023 they built the aggregator they wanted: a waterfall across dozens of providers, billed once, with a rule that you never pay for data the system cannot verify. It grew quickly, raised roughly 1.9 million euros led by Flex Capital in early 2025 after reaching seven-figure revenue while bootstrapped, and now counts Mastercard, DocuSign, and Brevo among its customers.

The credit table is the clearest expression of what the product is. A verified work email is one credit. A personal email is three. A verified mobile phone number is ten. A reverse email lookup is one. B2B profile and company data costs a quarter of a credit and is included free alongside an enrichment. Nothing at all is charged for a result the waterfall cannot verify, which the vendor states as verified or it is free. That table makes it possible to model a month of enrichment on paper before spending anything, which is more than most vendors in this category permit.

Pricing is unusually simple and unusually thin at the same time. There is a free tier with 50 starter credits and no card, then one published paid plan: Pro at 55 dollars a month for 1,000 credits. Larger volumes exist, and the pricing page runs a calculator up through 100,000 credits, but only the 1,000 credit step carries a published price. Everything above it, along with bring-your-own provider keys, custom rate limits, SSO, and reseller terms for agencies, sits behind Enterprise. Credits roll over for three months on monthly billing and twelve on annual.

What sets FullEnrich apart from the other waterfalls is the developer surface. It ships three APIs, an enrichment API, a search API, and a reverse email lookup API, and an MCP server available on all tiers including free, which means an AI assistant can call enrichment directly rather than a human copying rows between tools. For a fourteen-person company that is a meaningful bet on where this category is going, and it is currently the most complete answer to the question of how enrichment fits into an agentic workflow.

## How it works

1. You bring identities: a name plus a company, a domain, a LinkedIn profile, or an email address for reverse lookup. Contacts arrive through the web app, a CSV upload, the API, or a tool like Clay that calls FullEnrich as a provider.

2. For each record the waterfall runs. More than twenty-five providers are queried in sequence until one returns data that FullEnrich can verify, so a contact one vendor misses is picked up by another rather than being lost.

3. Verification decides billing. A verified work email costs one credit, a verified personal email three, a verified mobile ten. B2B profile and company attributes cost a quarter of a credit and ride along free with an enrichment. If nothing verifiable comes back, nothing is charged.

4. Results leave through one-click export, a CRM or sequencer integration, the API, or the MCP server, which lets Claude and other assistants request enrichment as a tool call rather than requiring a person to run the job.

5. Unused credits roll forward: three months on monthly billing, twelve on annual, so a project-driven team is not forced to spend an allowance evenly.

## Best for

Teams that need high coverage on both emails and mobile numbers from one vendor and want to consume enrichment programmatically, especially developers and GTM engineers building pipelines or wiring data into an AI assistant through MCP.

## Not the right fit for

- Buyers who want the cheapest possible cost per email; at 5.5 cents a work email on the published plan, single-source vendors are three to five times cheaper.
- Teams that need to discover who to contact; FullEnrich enriches identities you already have and is not a filterable prospecting database.
- Anyone who needs published pricing above 1,000 credits a month; only the entry step carries a price and everything larger requires a quote.
- Organisations with strict data provenance rules; a waterfall deliberately abstracts which of twenty-five providers supplied a given record.
- Small teams that need bring-your-own provider keys or SSO to make the economics or the security review work, since both are Enterprise-only.

## Features

### Waterfall enrichment

Twenty-five sources behind one credit balance.

- **More than twenty-five data sources**: Providers are queried in sequence per contact, so geographic and industry gaps in any one vendor are covered by the others in the chain.
- **Verified or it is free**: Credits are consumed only when the waterfall returns data it can verify; unverifiable results cost nothing, which puts a hard floor under wasted spend.
- **Waterfall on all plans**: The full source set is available from the free tier upward rather than being reserved for higher plans, unlike BetterContact, which runs a shorter chain on Starter.
- **Global coverage focus**: The aggregation approach is explicitly aimed at international lists, where any single provider's coverage collapses outside its home market.
- **Bring your own API keys on Enterprise**: Enterprise customers can plug in their own provider contracts so upstream data bills against rates they have already negotiated.

### Data types and the credit table

Four priced outputs, published plainly.

- **Verified work email at one credit**: The base unit, at 5.5 cents on the published Pro plan, charged only when verification succeeds.
- **Personal email at three credits**: A separate and more expensive data type, which almost no competitor in this batch offers at all as a distinct priced output.
- **Verified mobile phone at ten credits**: About 55 cents per number on the published plan, with the exchange rate stated up front rather than negotiated.
- **Reverse email lookup at one credit**: Turns an address into the person and company behind it, useful for identifying inbound signups, at the same price as a forward lookup.
- **B2B profile and company data at a quarter credit**: Firmographic and profile attributes are the cheapest output and are included free alongside an enrichment rather than billed twice.

### Developer surface and MCP

The clearest differentiator against the other waterfalls.

- **MCP server on all tiers**: A Model Context Protocol endpoint available from the free plan upward, so Claude and other assistants can call enrichment as a tool rather than requiring a person to run a job.
- **Enrichment API**: Programmatic single and bulk enrichment, available on Pro and Enterprise, which is how most volume customers consume the product.
- **Search API**: A separate endpoint for finding contacts rather than only enriching known ones, extending the product past pure enrichment.
- **Reverse email lookup API**: Resolve an address to a person and company programmatically, at one credit per lookup.
- **Custom rate limits and priority queue**: Throughput above the standard limits is an Enterprise arrangement, so high-volume pipelines need a conversation before they scale.

### Delivery and integrations

Designed to be called by other tools.

- **Clay integration**: Callable as a provider inside Clay, replacing a hand-built chain of individual provider columns with one column and one unit cost.
- **CSV upload and export**: Direct file workflow for one-off list work with results downloadable in the same shape.
- **CRM and sequencer connectors**: Native paths into the common outbound stack so enriched records land where the sending happens.
- **Chrome extension**: Enrich from a LinkedIn profile or company page without leaving the browser.
- **Referral credits on the free tier**: The free plan earns additional credits through referrals rather than resetting to a fixed monthly allowance.

### Commercial and governance terms

Generous rollover, Enterprise-gated governance.

- **Three month rollover on monthly billing**: Unused credits carry forward for three months, which absorbs a slow month without forcing you to downgrade.
- **Twelve month rollover on annual billing**: Annual buyers get a year-long pool, so a seasonal or campaign-driven team can spend unevenly.
- **SSO and team governance on Enterprise**: Custom single sign-on and governance controls exist but are reserved for Enterprise, so a small team cannot buy them.
- **Reseller and agency terms**: Enterprise includes reseller agreements and co-marketing for agencies, which is a real commercial path rather than a footnote.
- **European origin, US presence**: Founded in France and now operating from San Francisco, which means EU buyers should confirm the current processing and contracting entity rather than assuming EU residency.

## Use cases

- **Developer wiring enrichment into an AI agent**: An internal assistant needs to enrich inbound signups on demand, and the current setup requires a human to run a batch job and paste results back. Outcome: The MCP server, available even on the free tier, lets the assistant call enrichment directly as a tool, and the reverse email lookup at one credit turns a bare signup address into a qualified record.
- **Sales team working international accounts**: Targets are spread across Europe, North America, and APAC, and every single-source vendor covers one region well and the others badly. Outcome: The twenty-five source waterfall closes the regional gaps, mobiles come from the same credit pool at ten credits each, and the records it cannot verify cost nothing.
- **Agency reselling enrichment to clients**: Client work needs both emails and phone numbers, margins depend on not paying for unusable data, and the agency wants its own commercial terms. Outcome: Verified-or-free billing protects the margin, the published credit table makes client recharging defensible, and Enterprise offers reseller agreements plus bring-your-own provider keys.
- **GTM engineer collapsing a Clay waterfall**: A Clay table calls eight providers in separate columns, each with different failure behaviour, and nobody can state the cost per enriched row. Outcome: One FullEnrich column replaces the chain, the unit cost becomes one credit for a work email or ten for a mobile, misses stop consuming anything, and company data rides along at a quarter credit.

## Pricing

Freemium subscription with a published entry plan and quoted volume above it, priced from a single credit pool where different data types consume different credit amounts and unverifiable results cost nothing.

- **Free**: $0 one-time 50 credits. 50 credits to start, no card required; Full waterfall across 25 plus sources; MCP server access; Referral credits to extend the allowance. Enough to test the hit rate on a real list, which is the only meaningful evaluation of a waterfall.
- **Pro**: $55 per month (1,000 credits, $0.055 each). 1,000 credits per month; Waterfall across 25 plus sources; Enrichment, search, and reverse lookup APIs; MCP server; 3 month rollover monthly, 12 month rollover annually. The only paid step with a published price; larger volumes are quoted.
- **Enterprise**: Custom monthly or annual. Custom credit volume above 1,000 per month; Bring your own provider API keys; Custom rate limits and priority queue; Custom SSO and team governance; Reseller agreements and co-marketing for agencies. Everything that makes the economics work at scale, including BYOK, lives here.

Billing notes:

- The credit table is published and granular: one credit for a verified work email, three for a personal email, ten for a verified mobile, one for a reverse email lookup, and a quarter credit for B2B profile and company data, which is included free alongside an enrichment.
- Nothing is charged for a result the waterfall cannot verify. The vendor states this as verified or it is free, which is the strongest form of the pay-on-success rule and matches BetterContact's promise.
- Only the 1,000 credit step at 55 dollars a month carries a published price. The pricing page runs a calculator up through 100,000 credits, but those are inputs rather than published tiers, so any real volume purchase involves a quote.
- Credits roll over for three months on monthly billing and twelve months on annual, which is more generous than a hard monthly reset and comparable to Hunter's twelve month validity.
- There is no per-seat charge on the published plans, so cost scales with enrichment volume rather than with team size.
- Bring-your-own provider API keys, custom rate limits, and SSO are Enterprise-only, so a small team cannot shift upstream data costs onto its own contracts or pass a security review that requires single sign-on.

Value assessment: At 1,000 lookups the Pro plan costs 55 dollars, or 5.5 cents per verified work email, which is roughly six times Icypeas and slightly more than BetterContact's entry rate. At 10,000 the price is not published, so the honest answer is that you cannot model it without a quote, and that opacity is the main weakness of an otherwise transparent product. What the premium buys is coverage from twenty-five sources, a floor on waste because unverified results are free, personal emails and reverse lookup as distinct priced outputs, company data at a quarter credit, and an MCP server on every tier. For an international list or an agentic workflow that is a genuinely differentiated package. For a well-covered domestic list, you are paying waterfall prices for a problem you do not have.

## Strengths

- Twenty-five plus providers in one waterfall, available on every tier including free, which is broader than most competitors and not gated behind an upgrade.
- Verified or it is free is the strongest available billing guarantee, and the granular credit table lets you model a month's spend precisely before committing.
- An MCP server on all tiers, including the free plan, is the most complete answer in this category to how enrichment plugs into an AI assistant.
- Three separate APIs, for enrichment, search, and reverse email lookup, rather than a single endpoint bolted onto a web app.
- Personal emails and reverse email lookup are distinct priced outputs, which almost no competitor in this batch offers.
- B2B profile and company data at a quarter credit, included free alongside an enrichment rather than billed as a second lookup.
- Credit rollover of three months monthly and twelve months annually, which is generous for a waterfall vendor.
- Backed by roughly 1.9 million euros led by Flex Capital after reaching seven-figure revenue bootstrapped, with Mastercard, DocuSign, and Brevo cited as customers, so it is better capitalised than most vendors in this batch.

## Limitations

- Only the 1,000 credit step is publicly priced. Anything above it requires a quote, which is a real transparency gap in a category where competitors publish ladders to 100,000 credits.
- At 5.5 cents per verified work email the entry rate is among the most expensive here, several times what a single-source vendor charges.
- Bring-your-own provider keys, the feature that fixes the unit economics at volume, is Enterprise-only, as are custom rate limits and SSO.
- The waterfall abstracts which of twenty-five providers supplied a given record, which will not satisfy a strict data provenance policy.
- No prospecting database in the sense of filterable people search, so list building happens elsewhere first.
- Standard API rate limits are not prominently published, with custom limits reserved for Enterprise, so a high-volume pipeline needs a conversation before it scales.
- The company was founded in France and now operates from San Francisco, so EU buyers should confirm the contracting and processing entity rather than assuming European residency.
- Fourteen people carrying enterprise-named customers means support and roadmap depth are thinner than the logo list implies.

## Comparisons

- **FullEnrich vs BetterContact**: Near-twins on the core mechanic: both waterfall across twenty-plus sources, charge one credit per verified email and ten per verified mobile, and refuse to bill for data they cannot verify. FullEnrich adds an MCP server on every tier, personal emails at three credits, reverse lookup, and longer rollover; BetterContact answers with a 15 dollar entry point, an explicit no-charge-for-catch-alls rule, and a fully published ladder to 50,000 credits. Take FullEnrich for the developer surface and the broader data types; take BetterContact if you need to know what 10,000 credits costs without asking.
- **FullEnrich vs Datagma**: Datagma is a single brokered source that FullEnrich's waterfall can call, so this is orchestration versus supply. Datagma is cheaper per mobile at thirty of its own credits, includes ten seats, and publishes its full ladder; FullEnrich will find records Datagma alone misses and charges nothing when it fails. Buy Datagma to optimise the phone line item on a small team; buy FullEnrich when coverage across regions is the bottleneck.
- **FullEnrich vs Enrich**: Both are API-first, but they price very differently. Enrich charges ten credits per email against a 100,000 credit pool for 49 dollars, an order of magnitude cheaper per record on paper, and 500 credits per phone. FullEnrich runs a longer verified waterfall, offers personal emails and an MCP server, and guarantees you pay nothing for unverified data. Price-led API buyers should test Enrich first; teams that need verified coverage and AI-assistant access should pay FullEnrich's premium.
- **FullEnrich vs ContactOut**: ContactOut owns a 300 million profile database with recruiter tooling, ATS integrations, and separate email and phone credit pools, sold per seat on annual terms with monthly fair-use caps. FullEnrich owns nothing and aggregates twenty-five sources, sold by credit with no seat charge. Recruiters working LinkedIn all day take ContactOut; engineering and GTM teams enriching records programmatically take FullEnrich.
- **FullEnrich vs Clay**: Complements more than rivals: FullEnrich is callable as a single Clay column and frequently replaces a hand-built chain of provider columns. Clay is what you buy for AI research, scoring, conditional logic, and workflow orchestration; FullEnrich is what you buy for the highest verified hit rate per contact at a stated unit cost. Teams running serious outbound commonly pay for both, using FullEnrich as the enrichment step inside Clay's orchestration.

## Implementation

- Setup time: Ten minutes for a CSV run or a Clay column, under an hour for the API, and a few minutes for the MCP server, which is the fastest path to useful for anyone already working in an AI assistant.
- Learning curve: Low, provided the team learns the credit table. The ten-to-one mobile rate and the three-to-one personal email rate mean a plan's usable size depends entirely on the mix, and teams that assume every output costs one credit will exhaust an allowance in days.
- Onboarding: Self-serve on Free and Pro. Enterprise adds a dedicated account manager, priority support, custom rate limits, SSO, and bring-your-own-keys configuration, and is the only route to volume pricing.
- Migration: Nothing to migrate in beyond a CSV or an API connection, and enriched records are yours to export on the way out. The genuine switching consideration is coverage: a waterfall's hit rate is hard to replicate with a single vendor, so test any replacement against the same list before cutting over, not after. Rolled-over credits are also forfeited when a subscription ends, so spend the balance down first.

## Platform, API & security

- Platforms: Web application, Chrome extension, CSV upload, REST APIs, MCP server, Clay integration
- API: Three documented APIs: enrichment, search, and reverse email lookup, available on Pro and Enterprise. An MCP server is available on all tiers including free, letting AI assistants call enrichment as a tool. Standard rate limits are not prominently published and custom rate limits with a priority queue are an Enterprise feature, so confirm throughput before building a high-volume pipeline.
- Compliance: GDPR, CCPA, Data processing agreement available
- Data residency: Founded in France and now operating from San Francisco; no customer-selectable region is advertised, and EU buyers should confirm the current contracting and processing entity.
- SSO: Custom SSO is available on Enterprise only.
- Security notes: FullEnrich aggregates more than twenty-five upstream providers rather than holding a large owned contact database, so its own footprint is narrow but a complete provenance answer depends on the sourcing of every provider in the chain. No SOC 2 or ISO 27001 certification is published on the pricing or product pages.

## Support

- Channels: Email support, In-app chat, Priority support and a dedicated account manager on Enterprise
- Documentation: API documentation covering the enrichment, search, and reverse lookup endpoints, plus MCP server setup and the credit cost table.
- Community: No official forum; strong presence in GTM engineering and outbound agency communities, plus reseller and co-marketing arrangements with agencies on Enterprise.

## FAQ

### What is FullEnrich?

FullEnrich is a waterfall enrichment platform. For each contact it queries more than twenty-five B2B data providers in sequence until one returns a verified work email, personal email, or mobile phone number. You pay one subscription rather than twenty-five, and you pay nothing for results it cannot verify.

### How much does FullEnrich cost?

There is a free tier with 50 starter credits and no card required, then Pro at 55 dollars a month for 1,000 credits, which works out at 5.5 cents per credit. Above 1,000 credits, pricing is quoted rather than published, along with bring-your-own provider keys, custom rate limits, SSO, and reseller terms.

### Does a failed lookup consume a credit?

No. FullEnrich states verified or it is free: credits are consumed only when the waterfall returns data it can verify, and unverifiable results cost nothing. This is the single most consequential billing question in this category, and FullEnrich answers it in the strongest form, alongside BetterContact.

### What does each data type cost in credits?

A verified work email is one credit, a personal email is three, a verified mobile phone number is ten, and a reverse email lookup is one. B2B profile and company data costs a quarter of a credit and is included free alongside an enrichment. On the published Pro plan that means about 5.5 cents per work email and about 55 cents per mobile number.

### Do credits roll over?

Yes. Monthly billing carries unused credits forward for three months and annual billing for twelve. That is more generous than a hard monthly reset and comparable to Hunter's twelve month credit validity, though less generous than Icypeas, whose credits never expire. Rolled-over credits are forfeited when a subscription ends, so spend the balance down before switching.

### What is the MCP server for?

It exposes FullEnrich's enrichment through the Model Context Protocol, so Claude and other AI assistants can request a lookup as a tool call rather than a person running a batch job and pasting results back. It is available on all tiers including free, which is unusual, and it is currently the most complete answer in this category to how contact enrichment fits into an agentic workflow.

### Can I bring my own provider API keys?

Only on Enterprise. That is the feature that fixes the unit economics at volume, because upstream data then bills against contracts you have already negotiated while you pay FullEnrich for the orchestration and verification. On the free and Pro tiers you pay the blended rate, which is why the published 5.5 cents per email looks expensive next to a single-source vendor.

### Where does the data come from?

From more than twenty-five upstream providers rather than from a database FullEnrich owns. That is good for coverage, particularly on international lists where any single vendor's quality collapses outside its home market, and awkward for governance: the waterfall deliberately abstracts which provider supplied a given record. If your data policy requires naming the source of each contact, this architecture will not satisfy it.

### How does it handle GDPR for European contacts?

A data processing agreement is available and the company states GDPR and CCPA compliance. Note that FullEnrich was founded in France but now operates from San Francisco, so an EU buyer who cares about establishment and transfer mechanics should confirm the current contracting and processing entity rather than assuming European residency. As always, the lawful basis for your outreach is your own legitimate interest assessment, and in a waterfall you inherit the sourcing questions of every provider in the chain.

### Is FullEnrich worth the premium over a single-source vendor?

It depends on your lists. On a well-covered domestic list, a cheap single source plus a verifier does the same job for a fraction of the money. On international, mid-market, or hard-to-reach segments where one provider returns half your records, the waterfall pays for itself immediately, and the verified-or-free rule puts a firm floor under waste. The MCP server and the personal email and reverse lookup data types are additional reasons that have nothing to do with hit rate.

## Editorial verdict

FullEnrich is the most technically ambitious of the small waterfall vendors. Twenty-five sources on every tier including free, a granular published credit table, a verified-or-free billing rule, personal emails and reverse lookup as distinct outputs, company data at a quarter credit, and an MCP server that lets an AI assistant call enrichment directly. With roughly two million dollars of seed funding behind it and Mastercard and DocuSign on the customer list, it is also better capitalised than most of its peers. Buy it if you work international lists, if you consume data programmatically, or if you want enrichment available to an agent rather than to a person. The two things to weigh are the price, at 5.5 cents per verified work email on the only published plan, and the fact that everything above 1,000 credits a month, including bring-your-own keys and SSO, requires a quote you cannot see in advance.
