Clay lands $115-million USD Series D at $7-billion valuation

Clay, a Canadian-founded go-to-market AI startup based in New York City, has closed a $115-million USD (approximately $159 million CAD) Series D round that values the company at $7.1 billion USD. The financing was led by Wellington and included participation from Andreessen Horowitz, CapitalG, Meritech, Sequoia and others. The raise follows a $100-million Series C in August 2025 that valued the company at $3.1 billion USD and comes as Clay reports it now serves more than 17,000 customers — up from 10,000 a year ago — including Anthropic, ElevenLabs, Google, OpenAI, Siemens and Stripe.

“AI is unleashing the biggest wave of company creation in history, and Clay’s goal is to be the engine those companies use to grow to their full potential,” Clay co-founder and CEO Kareem Amin said in the announcement. “We started by aggregating the best data for [business-to-business] companies. Then, we built the infrastructure to run any personalized campaign on top of it. Now, we’re building agents that can help grow your company for you.”

Context and company background

Launched in 2017 by McGill University graduates Kareem Amin and Nicolae Rusan, Clay has pursued an ambitious roadmap to become what it calls “the AI growth engine for every company.” Rusan, who is Canadian, has since left the company. Amin, originally from Egypt, attended McGill before relocating to the United States more than a decade ago; he and Rusan previously built an e-commerce technology startup, Frame, which they sold to Sailthru in 2012.

Clay sells AI software and autonomous agents that automate marketing, sales and other go-to-market functions. The company says its product suite includes a “self-learning revenue engine” made up of agents capable of identifying prospective clients, monitoring intent signals, drafting personalized outreach and updating customer relationship management systems. Clay’s growth in paying customers and the size of the new round underscore investor confidence in that agentic approach.

• Notable customers: Anthropic, ElevenLabs, Google, OpenAI, Siemens, Stripe
• Early investor: Canadian-founded Maple VC

Outlook

Investors and supporters are positioning Clay as a potential successor to legacy CRM and revenue platforms. “Just as [large language models] predict the next best word in a sentence, Clay will predict the next best action to grow your business,” Maple VC general partner Andre Charoo said, adding that he believes Clay could become “the agentic successor to Salesforce.”

With its new $115-million infusion and a valuation more than double its Series C price, Clay faces the operational challenge of scaling its agent-driven product across a broad client base while proving that autonomous GTM agents can deliver sustainable, measurable revenue outcomes at enterprise scale. The company’s traction — rapidly growing customer numbers and marquee users across AI and enterprise sectors — will be watched closely by investors and competitors as Clay pushes to convert its vision of autonomous revenue generation into mainstream adoption.
