Coldreach

Coldreach is a Y Combinator-backed (W23) AI sales development platform that helps B2B teams find companies that are ready to buy right now. Instead of blasting cold emails to random lists, teams describe what a buying signal looks like for their product in plain language, and Coldreach monitors 113M+ companies across job postings, news, LinkedIn activity, SEC filings, hiring changes and more, 24/7. 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.
