Clay hits $7.1B on $115M Series D as Wellington prices AI GTM automation for pre-IPO

Wellington-led round more than doubles Clay's valuation in 13 months; company says it's tracking to $200M ARR this quarter across 17,000 customers.

Clay closed a $115 million Series D on September 9 at a $7.1 billion valuation, led by Wellington Management, with Sequoia, StepStone, a16z Perennial, Meritech, DST, CapitalG, BoxGroup, Boldstart, Bloomberg Beta, and Evolution returning. The New York-based go-to-market company says it grew revenue 4x in 2025 and is tracking to $200 million ARR this quarter, per Crunchbase, with $240 million projected by fiscal year-end.

The mark-up is the news underneath the news. Clay priced at $3.1 billion in August 2025 on a CapitalG-led Series C, cleared a $5.0 billion employee tender via DST in January 2026, and now doubles that in eight months. Wellington’s presence, per TechFundingNews, is the tell: crossover funds anchor pre-IPO rounds because they intend to own the equity through the listing.

The customer roster is unusually concentrated at the top of the AI hierarchy. Clay claims 17,000+ customers, including Anthropic, Google, OpenAI, Stripe, ElevenLabs, Workday, and Siemens, and says it serves roughly 80% of the Forbes AI 50. The platform pulls from 150+ external data sources to enrich prospecting and personalize outreach at scale. A “Sculpt” event is scheduled for October 8 in San Francisco.

Zoom out and the category is being repriced in real time. Sales, marketing, and CRM startups have taken in $7.5 billion globally in 2026 across 830 rounds, with AppsFlyer’s $1B+ Series E and Parloa’s $350 million Series D bracketing Clay. That pace still trails the $27 billion peak of 2022, but the money is now concentrated in AI-native GTM infrastructure rather than sprayed across the SaaS surface.

The structural read is straightforward. Investors are paying pre-IPO multiples for the thesis that automated customer acquisition is core revenue infrastructure, and the widening gap between teams that run it and teams that don’t is now a priced-in bet. Clay sells the workflow to GTM engineers. Founder-led operators who want the output rather than the platform can compare that positioning against the done-for-you approach at LemonLime, and against this year’s other repricings in the hardware-to-software rotation and Jefferies’ moat-wins call.
