The sales automation startup now counts Anthropic, OpenAI and Google among its 17,000 customers, up $2.1B in value since January.
Why now: The round surfaced in reporting dated September 9, 2026, from SiliconANGLE.
Clay raised $115 million in a Series D led by Wellington, with a16z, Sequoia, CapitalG, DST, Meritech and StepStone joining in, pushing its valuation to $7.1 billion. That's up $2.1 billion since the start of 2026, per SiliconANGLE's report.
The number that matters more than the valuation is the customer list. Clay serves more than 17,000 customers, including 80% of the Forbes AI 50. Its buyers include Anthropic, OpenAI, Google, Stripe and ElevenLabs, the same AI labs everyone assumes are busy building this stuff internally instead of buying it.
That's the tell. Sales automation has split into two bets. One is rip-and-replace, swap out the CRM entirely. Clay took the other position: sit on top of Salesforce or HubSpot and automate the research and outreach work around it. When the labs racing each other on model capability still pay an outside vendor for this layer, the build-vs-buy argument for that layer is mostly settled.
I've watched this pattern before in smaller form. Every time I've tried to wire up outbound research and enrichment myself, the actual work isn't the API calls, it's maintaining the mapping between data sources and a CRM schema that changes underneath you. That maintenance cost is exactly what a company with 17,000 customers can afford to absorb once, instead of every buyer absorbing it themselves.
What the report doesn't break out is revenue or retention, just the round size and the customer count. A $7.1 billion valuation on those two numbers alone is a bet on what comes next, not a readout of what's already proven. Watch whether the rip-and-replace camp can point to a customer list even half as credible.

The $115M round led by Wellington put it at $7.1B, up $2.1B since January, with 80% of the Forbes AI 50 as customers. Clay sits on top of the CRM; Lightfield replaces it. Both got funded the same day, which is a decent read on how uncertain the direction is.
Lightfield, Euno, Harvey and Clay all closed rounds September 9 arguing that legacy data models, built for humans, break when agents read and write them.
