Lavender wants your cold email to earn its reply
A startup rescued by cold outreach built a coach for the inbox. Now Lavender is handing the keyboard to an AI agent - and asking whether better research can keep automation from becoming everybody else’s spam.
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.
Revamp (YC S23)
Revamp is a San Francisco startup (YC Summer 2023) that builds AI agents for eCommerce retention marketing. It plugs into Klaviyo and Shopify to turn scattered customer data into smart segments and then writes genuinely 1:1 personalized emails - drawing on signals like location, weather, purchase history and browsing behavior - so D2C brands can lift email revenue without hiring an army of copywriters.
