About
Warmer AI is an AI-powered B2B sales enrichment and outreach personalization platform designed to help SDR teams, marketers, and sales professionals move beyond generic cold email templates. By simply uploading a CSV of prospects, Warmer automatically researches each lead using social profile scraping and company intelligence gathering—extracting job titles, recent activity, company size, industry, funding news, and more. Once enriched, Warmer's custom AI sales agent model generates unique, human-feeling messages tailored to each individual prospect. Unlike mass email sequences that land in spam, these hyper-personalized messages reference real, specific details about the recipient, dramatically improving reply rates. Users report going from 2% to 18%+ response rates after switching to Warmer. The platform also includes email validation and deliverability verification to reduce bounce rates, and a RESTful API that enables custom workflow integrations with CRMs, email platforms, and internal tooling. Data can be exported in CSV or JSON formats. A social enrichment API is available for developers who want to embed enrichment capabilities directly into their own applications. Warmer is best suited for B2B sales teams, SDRs, growth marketers, and revenue operations professionals who need to personalize outreach at volume without sacrificing quality. It eliminates hours of manual LinkedIn research and lets sales reps focus on conversations that convert rather than prospecting busywork.
