# A prospecting tool and matching marketplace

Your data is training someone's model. You're just not getting paid.

Highford is a prospecting tool and a matching marketplace. Search a database of listings, find a counterparty, and reach them with a double opt-in intro. AI data is the first wedge. The same path covers businesses, startups, talent, judgments, and more.

## What it is

Highford has two halves:

1. A searchable database of listings and the people and companies behind them.
2. A matching marketplace. When you want to reach someone, the next step is a double opt-in intro. They accept or decline from a link in the email.

## Who it's for

- People looking for a counterparty, and people who want to be found.
- Agents acting for a person. Search, unlock, and intro work the same way through the API or MCP. A person and their agent share one allowance.
- Teams working on AI training data. That category came first. It is not the whole marketplace.

## What you can find

Each listing is public. The contact stays locked until you unlock it.

- [Datasets](/data) and [data requests](/data/requests).
- [Businesses for sale](/for/business-owners).
- [Startups](/for/founders).
- [Talent and experts](/talent).
- [Judgments and awards](/for/claimants-and-funders).
- [Wanted posts](/wanted), where someone states what they are looking for.

## How it works

1. Search listings. Summary search needs no key. People and agents use the same search.
2. Unlock a listing to see the contact's name and email. Unlocking the same listing again is free.
3. Request an intro. Preview the draft, then confirm. Outreach is never automatic.
4. The contact decides. If they decline, the free intro, or the paid credit, comes back.

Listing and search are free, and there's a free tier for contact unlocks and intros. See [pricing](/pricing).
