// What it does

Search candidates, read the full profile, send a connection request with a note about the role, follow up once accepted. Your ATS or your agent decides who and what; the API sends, paces and reports back.

// Three workflows teams ship with it

Use case · ATS

From saved search to first message

Recruiters save a search in your product. New matches get a personal invitation, then the job link once they accept.

42 candidates matched, Invitations paced, 9 accepted · messaged

People search API

Use case · Agency

Multi-channel follow-up per candidate

No answer on LinkedIn after five days? The email finder returns an address and the same sequence continues by email.

No reply · day 5, Email found, Follow-up sent

Email finder API

Use case · AI agent

An agent that screens before it invites

Over MCP, the agent reads each profile against the job spec, keeps the fits, writes the note and sends the batch you approve.
