Clay is a data enrichment and outreach tool that automates the research-intensive work of sales prospecting. Build a list of target companies, and Clay enriches each with data from 100+ sources — funding rounds, tech stack, job postings, LinkedIn activity, news mentions — automatically, in seconds. AI-powered personalization then generates outreach messages tailored to each prospect using the enriched data: 'I noticed you just raised a Series B and are hiring engineers — here's how we've helped similar companies...'. The result is highly personalized outreach at scale that would take a team of SDRs weeks to produce manually. For growth teams, founders doing their own outreach, and sales teams that want quality over volume, Clay compresses the research-to-message workflow into something that runs automatically.
