About
Clay is a GTM data enrichment and outbound automation platform founded in 2021, built on the thesis that go-to-market teams should be able to build sophisticated data workflows without engineering support. The platform acts as a spreadsheet-like interface that connects to 100+ data providers simultaneously — including LinkedIn, Clearbit, Hunter, and custom APIs — allowing sales and growth teams to enrich leads, score accounts, and automate personalized outreach at scale. Clay's core technology is its waterfall enrichment engine, which queries multiple data sources in sequence to maximize coverage and data freshness for any given record.\n\nClay's product is used by growth engineers, demand generation teams, and RevOps professionals at companies ranging from early-stage startups to enterprise accounts. Users build enrichment tables, run AI-generated personalization at scale using built-in Claude and GPT integrations, and push outputs directly into CRMs like Salesforce and HubSpot or sequencing tools like Outreach. Customers include OpenAI, Anthropic, Notion, and hundreds of high-growth B2B companies that have replaced fragmented data stacks with Clay's unified enrichment layer.\n\nClay reached $100M ARR in roughly two years, a milestone that tracks with explosive word-of-mouth adoption in the GTM engineering community. The company raised a $100M Series C at a $3.1B valuation led by CapitalG (Google's independent growth fund) in 2024, with 10,000+ paying customers. Clay has become the default infrastructure layer for modern outbound sales teams and is widely credited with defining the "GTM engineer" job category.
