Clay

Clay is an AI-powered go-to-market platform founded in 2017 and headquartered in Brooklyn. Its platform combines data infrastructure, agentic workflows and GTM play execution, giving sales and growth teams the tooling to enrich customer data and automate personalised outreach at scale. The technical stack spans AI/ML, agentic workflow orchestration, data enrichment and aggregation, sales automation and personalised outreach generation.

The product aggregates more than 150 data providers in one place, allowing users to research target companies, enrich records and find contact information without switching between vendors. On top of that data layer, Clay runs AI-driven research and builds personalised outreach sequences, work that would previously have required an entire team and can now be executed by one person. This combination of data aggregation and agentic automation is what marketing engineers work with day to day.

Clay employs more than 500 people and serves over 14,000 customers worldwide, including Anthropic, Notion, Google and Ramp. The company crossed $100m in revenue in 2025, raised a $100m Series C that year, and is valued at $5 billion. Its backers include Sequoia, CapitalG and First Round Capital.

The ecosystem around the product is substantial: 150+ integration partners, more than 125 agencies in its community, over 50 Clay clubs and a 30,000-member Slack community. It operates across the sales and go-to-market, growth marketing, SaaS and agency verticals.
