Do I need Grinfi to use it?

No. Lead Finder is a standalone product. If you use Grinfi, lists can land straight in a Grinfi campaign.

Where does the data come from?

Public professional profiles and company pages, and Google Maps for local businesses. Every candidate is checked by AI against your brief.

Is it GDPR-compliant?

Yes. Data is stored in the EU; for the people we find you are the controller and we are your processor, under the same terms as Grinfi and Telegrin.

Can my agent spend money without me?

No. Every paid step is approved by you on our page, not by the agent.

What if a lead does not match?

Every lead carries the reason it was accepted. Mark the ones you disagree with - it sharpens the next collection.

Can I continue a search later, or get new people in the same portrait?

Yes. The same brief continues where it stopped, and people you already got are skipped for free. Ask for a refresh to get only the people who appeared since last time. A different portrait is a different list: the file marks people you already have in your other lists.

Can I use it without Claude?

Yes - from Codex or any MCP client, or by API. Claude is the easiest way, not the only one.

How it works

Three steps, no dashboard to learn

Describe who you need

In your Claude, in plain words. The agent asks what matters: who to exclude, which countries, titles, company size - and shows you the brief before anything runs.

Approve the price

We check a first sample and quote a price per matching lead. You approve with one click. Nothing is spent on the agent's word alone.

Get the list

People and companies that match, each with the reason. Download a CSV, send it to a webhook or straight into a Grinfi list. Re-download anytime, free.

What you get

Verified people and companies, not scraped rows

People who match

Name, title, company, location, profile link, summary - and why each person fits your brief.

Verified companies

Website, industry, headcount, founded year, headquarters - checked on the company page, not guessed.

Local businesses

Restaurants, clinics, studios, salons: venues from Google Maps with phone, website and rating - and the owner where there is one.

Expats and diasporas

Studied in one country, live in another. We pick the universities, you get the people.

Search in the local language

Titles and niche words translated for every country in your brief - Polish founders are found the way Polish LinkedIn names them.

Delivery your way

CSV with 30+ columns, a webhook, or a list straight in Grinfi. Emails on request.

Why teams pick it

Built for the way you already work

Your agent, not another dashboard

Everything happens in the Claude you already use. We are the tools it calls.

Verified by AI, explained to you

Every lead carries a verdict and the facts behind it. Missing data is flagged, never invented.

Pay for results, not seats

No subscription, no per-user pricing. A price per matching lead, quoted before you approve.

Honest about limits

What cannot be verified from public data - revenue, funding, growth - is flagged at the brief stage, before you pay.
