Clay (clay.com) is an AI-powered go-to-market platform that lets sales, marketing, and growth teams build highly personalized outbound campaigns without writing much code. The core product is a spreadsheet-like workspace where users pull data from 100+ third-party sources — contact info, firmographics, technographics, funding signals, job changes — then run AI research agents on top to write custom messaging at scale. Think of it as a programmable enrichment and automation layer sitting between a company's CRM and its outreach tools. The platform coined the "GTM Engineer" role — a technical operator who builds data pipelines and workflows to find, research, and reach ideal customers. Buyers are B2B revenue teams at companies ranging from high-growth startups to enterprises. Named customers include Anthropic, Notion, Google, Ramp, OpenAI, and Canva. Clay charges via a dual-meter model: Data Credits (covering third-party enrichment and AI costs) plus Actions (metering workflow execution steps like CRM syncs, HTTP calls, and AI tasks).
