Clay has raised $115 million in a Series D round at a $7.1 billion valuation, more than twice its $3.1 billion valuation in August 2025, as investors increase funding for companies developing AI agents. The New York-based startup builds tools that analyze business data, recommend next steps for sales teams and execute those actions. Its customers include Google and Anthropic. The round was led by Wellington, with participation from Sequoia, StepStone, Andreessen Horowitz and Perennial, among others. Founded in 2017, Clay previously raised $100 million in August 2025 in a CapitalG-led round. The company began by aggregating business-to-business data and building infrastructure for personalized campaigns before expanding into AI agents designed to support company growth. Clay has more than 10,000 customers, including OpenAI, Canva, Intercom and Rippling, and has been developing autonomous research agents, go-to-market automation workflows and the Claygencies agency network.
