How it works

Three steps, no dashboard to learn

1

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.

2

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.

3

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 can ask for

The list nobody else can sell you

Anyone can sell you job titles in a country. These are audiences that only exist if somebody goes and looks - and each lead arrives with the reason it is on the list.

Apps that are bleeding users

A 2.8 rating and four hundred angry reviews is a budget already looking for someone to spend it. You get the business behind the app, the person who owns the decision, and the exact sentence its users keep writing.

Companies at the age you sell to

Founded last year. Ten to fifty people on the books. In your industry, in your country. Taken from official company records, not guessed from a job title.

Every venue on a street you name

Restaurants, clinics, studios, salons in the cities you care about, each with phone, website, address and rating - and the owner wherever there is one to find.

Online stores that actually fit

Searched in the language the country uses, then read one by one: chains, franchises, resellers and suppliers are thrown out before they ever reach your list.

Founders who built it somewhere else

Studied in one country, running a company in another. We pick the universities and the countries; you get the people and a first line that is true.

The list you already have, finished

Hand over addresses or company names. You get the people behind them, verified, with the title, the company and the link.

And whatever else you can put in words. If the signal is public, we go and get it - and if it is not, we tell you before you spend anything.

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.
