Coldreach is a Y Combinator-backed (W23) AI sales development platform that helps B2B teams find companies that are ready to buy right now.

When a match fires, the AI researches the account and writes personalized outreach that references the specific event - which the company says produces meaningfully higher reply and booking rates than spray-and-pray outbound.
