B2B contact and company enrichment, delivered as an API

Primary sources checked

LinkFinder AI

Credit-metered lookup API that turns a name, company, domain or profile URL into a business email, a business phone number or a company record, run on the vendor's own infrastructure rather than through a browser extension.

The short answer

Best for
A recruiter or ops person who can call an API, or drive it from Google Sheets or n8n, and wants to pay per lookup
Not ideal for
Anyone who needs candidate discovery, personal mobile numbers, or enrichment inside an ATS — none of the three exists
Price
25 free credits, then from USD 49 per month for 5,000 credits (USD 29 per month on the annual FAQ), or credit packs from USD 25

Why these assessments
Recruitment fitWeak
The vendor sells this to sales and revenue teams: sales-named pricing tiers, sales CRMs and diallers as every integration destination, and no ATS anywhere. Recruitment is a permitted use in the Terms and two of roughly 220 pages address it. Recruiters can use it; it is not built for them.
Ease of useUnknown
What is established is the shape: an API key, one endpoint, a Sheets add-on. That is adoption effort, not daily usability, and there is no hands-on or independent evidence on file for the latter.
ImplementationFair
One endpoint, one bearer key, and a Google Sheets add-on for people who will not write code. But there is no recruiter-facing app: without the add-on or a workflow tool there is nothing to click, and an integration has to handle the documented polling behaviour.
Price transparencyFair
The meter is published endpoint by endpoint, which most rivals do not do. Against that, the same pricing page states two different credit costs for the same lookup, the annual cards disagree with the annual FAQ, and a fourth plan appears only in the API documentation.
Value for moneyUnknown
Value here is cost per usable contact, and that needs a match rate. No match rate is published for any market, failed lookups are charged, and SourcrLab has not run a sample. Judging it either way would be a guess.
ScalabilityFair
Credits and request rates scale cleanly to a documented 250,000 credits a month at 50 requests a second, and there are no seats to buy. What does not scale with it is the vendor: a French sole trader with no published team and no contractual uptime commitment below a custom arrangement.

The SourcrLab bottom line

Judge it as plumbing, not as recruitment software — the vendor sells it to sales teams and the integration list proves it. Three facts decide the bill. The API documentation prices each lookup separately, at 10 credits for a profile, 10 for a business email and 50 for a business phone; every request is charged even when nothing is found; and the data is business contact data by policy, so a low match rate in your market costs you twice. Set against that, the site's own claims about coverage, accuracy, latency and certification contradict each other from page to page, so nothing here should be bought on a published figure. Buy it on a sample run against the 25 free credits, which stretch to two profile lookups and no phone number at all.

Best fit

A lookup layer for a recruiter who already works in a spreadsheet or an automation tool and wants the contact question answered by an API call rather than by a person clicking through profiles. You bring the identifiers; it returns business contact and company fields, and it bills per lookup rather than per seat.

Think twice if

Recruiters who need to reach people who are not answering their work inbox. The vendor's privacy policy states it does not collect personal phone numbers or personal email addresses, so the two routes that most often reach a passive candidate are outside what this product holds. Nor does it find anyone: there is no search by skills, titles or boolean, and no ATS it writes into.

SourcrLab assessment

Everything on this page comes from the vendor's own pages, checked on the dates below. SourcrLab has not used this product in real recruitment work, so you will not find a first-hand opinion here.

Why choose LinkFinder AI?

The meter is published per lookup

The API documentation prices each endpoint: 1 credit for a company lookup, 5 to resolve a profile URL from an email, 10 for a full profile or a business email, 50 for a business phone number, and 1 per employee returned from a company domain. A recruiter can model a month's cost before signing, which is unusual in this category.

Nothing to install, and not your account

There is no browser extension anywhere in the product, and the documentation states lookups run without using your own LinkedIn account. For a team that has watched an extension-based tool put someone's profile at risk, that is a different architecture rather than a different setting. The vendor's own framing of the consequence, "zero ban risk", is its claim and not a checkable fact.

Company lookups from a name alone

The company endpoints need no domain and no URL. From a company name you can get the website, a business phone number, a business email, an employee count and the company page, each for one credit. For market mapping from a messy list of employer names, that is the cheapest part of the product.

An employee list with seniority filters

One endpoint takes a company domain and returns employees filtered by department and seniority, billed at one credit per employee returned. That is a list-building primitive rather than a single reveal, and it is the closest thing here to sourcing work.

A specific, published GDPR position

The privacy policy names legitimate interest under Article 6(1)(f), states that a balancing test was performed, publishes an opt-out that needs no proof of identity and completes within 30 days, names its subprocessors and states its retention. The controller is a French sole trader under CNIL supervision. That is more detail than several larger competitors publish, and it is checkable.

Automation surfaces that exist today

A Google Sheets Marketplace add-on that enriches a column in place, webhooks that post every result to a URL you own, importable n8n templates built on the HTTP Request node, and an MCP server. These are the ones the vendor's integrations page marks Live, and they need no waitlist.

Main trade-offs

It is sold to sales teams, not to recruiters

The footer on every page reads "B2B data enrichment API for sales and revenue teams". The plans are named for solo prospectors, sales teams and agencies. Every CRM and outreach destination on the integrations page is a sales CRM, a sequencer or a dialler, and no ATS or recruitment CRM appears at all. Recruitment is named as a permitted use in the Terms; it is not what the product is built around.

Failed lookups are charged

The API documentation states it directly: every request is charged, including lookups where no data is found. A business phone number costs 50 credits whether or not one comes back. In a market the vendor covers thinly, the bill grows fastest exactly where the tool is least useful.

Business contact data only, by policy

The privacy policy states the database holds a professional name, job title and employer, a business email, a business phone number, a public profile URL and a city and country — and that home addresses, personal phone numbers and personal email addresses are not knowingly collected. The API documentation nonetheless describes a "mobile number" field on the profile response, which the policy does not explain. Either way, do not plan a passive-candidate campaign around personal mobiles here.

It finds nobody for you

Every endpoint takes an identifier you already have: a profile URL, an email, a name plus a company, or a domain. There is no search by skills, titles or boolean, no shortlist and no messaging. Discovery still happens in LinkedIn, in your ATS or in a sourcing platform.

The published claims contradict each other

Coverage is given as 50M+ profiles on four pages and 500M+ on two others. Response time is 200ms on one page, under 100ms on another and about three seconds in the documentation, which also describes the richest endpoint as a live scrape taking roughly a minute. The pricing page states two different credit costs for the same lookup, and the annual plan cards disagree with the annual FAQ. Treat every published figure as a question for the vendor rather than a fact.

SOC 2 and uptime are asserted, not evidenced

Two marketing pages carry a "SOC 2 Compliant" badge and a 99.9% uptime figure, one of them labelled an SLA. No auditor, report or date is given, the privacy policy and terms name no certification at all, and the terms state the opposite of an availability promise: the service is not warranted to be uninterrupted, and SLA guarantees are offered only inside a custom arrangement. Ask for the report before relying on either.

The integration list is ahead of the integrations

The homepage advertises a native Zapier integration and shows logos for Make, HubSpot, Clay and Airtable. The vendor's own integrations page marks Zapier and Make as not yet submitted to their marketplaces, the n8n community node as not yet published, and the one-click Clay source as not built. What is Live is the API, webhooks, the Sheets add-on, n8n templates, an MCP server and HubSpot.

The counterparty is a sole trader, and no team is published

The footer, the privacy policy and the terms all name the same operator: an Entrepreneur Individuel registered in France. That is a legal form rather than a headcount — a sole trader may employ staff — but no team is published anywhere on the site, there is no SLA in the contract, and liability is capped at twelve months of fees. None of that is a reason to avoid the product; it belongs in the same sentence as any plan to make it load-bearing.

Where the data comes from is not settled

The privacy policy lists the sources as company websites, public business directories, professional disclosures and official corporate registries. It does not mention LinkedIn. The API documentation describes one endpoint as triggering a live LinkedIn scrape, and the site carries a page on scraping LinkedIn without getting banned. The terms make the buyer an independent data controller who must establish its own lawful basis, so this gap is the buyer's to close before an EU campaign, not the vendor's.

Pricing and buying reality

25 free credits, then from USD 49 per month

  • Free: 25 credits, no card required and no expiry countdown. Under the documented endpoint costs that is two profile lookups, or two business emails, and no phone number at all
  • Starter: USD 49 per month for 5,000 credits, 5 requests per second
  • Professional: USD 89 per month for 20,000 credits, 10 requests per second
  • Enterprise: USD 149 per month for 50,000 credits, 20 requests per second
  • Annual billing is described in the pricing FAQ as USD 29, 53 and 89 per month, saving USD 240, 432 and 720 a year. The plan cards themselves show the monthly figure in the annual position, so confirm the annual rate before signing
  • Pay as you go: USD 25 for 1,000 credits, USD 75 for 3,500, USD 200 for 10,000. These credits never expire, and cost two to eight times the subscription rate per credit
  • Credit costs per lookup, from the API documentation: company lookups 1, employees from a domain 1 per employee returned, company page 6, profile URL from an email 5, full profile 10, business email 10, business phone 50
  • Every request is charged, including lookups that return no data
  • Subscription credits do not roll over after cancellation. A 14-day money-back guarantee applies to a first payment
  • A fourth tier, HyperGrowth at 250,000 credits per month and 50 requests per second, appears only in the API documentation and carries no published price

What we do not know

  • Which credit costs actually apply: the pricing page's own FAQ states one credit for a profile, an email and a phone alike, contradicting the table above it and the API documentation
  • The real annual price, since the plan cards and the annual FAQ disagree
  • What the HyperGrowth tier costs, and from what volume
  • Whether the per-request volume discounts advertised on a second pricing page apply to the credit plans at all
  • The match rate in any market, without which cost per usable contact cannot be calculated

How it fits your stack

Works with

  • A Google Sheets Marketplace add-on that enriches a column in place
  • One REST endpoint with a bearer key, plus webhooks that post each result to a URL you own
  • Importable n8n templates and an MCP server
  • HubSpot, as a weekly pass that fills only empty properties

Likely replaces

  • A per-seat contact-data subscription, where the work is programmatic rather than a person clicking profiles
  • A browser extension, if your objection to one is that it runs on somebody's own account

May overlap with

  • People Data Labs on API-first enrichment, and Hunter on credit-metered email lookup
  • The enrichment already bundled into a sourcing platform or a recruitment CRM you pay for

Check before buying

  • The match rate on twenty-five real profiles from your own market, spent on the free credits before any plan
  • Which credit costs the vendor will actually bill, in writing, given its pages disagree
  • Whether business-only contact data reaches the candidates you need, or whether personal routes are the ones that work in your market
  • How the result gets into your ATS, since no ATS integration exists and a workflow tool has to bridge it
  • Your own lawful basis for approaching candidates on this data, since the terms make you an independent controller
