Clay Scores $100M Series C at $3.1B Valuation, Doubles Down on "GTM Engineering"

AI-powered sales platform Clay just closed a $100M Series C led by CapitalG (Alphabet's growth arm) at a $3.1B post-money valuation. The round included usual suspects Sequoia, Meritech, First Round, BoxGroup, and Boldstart, plus new money from Sapphire Ventures.

The Numbers That Matter:

• Revenue set to triple this year (exact figures undisclosed)
• 10,000+ customers including OpenAI, Anthropic, Cursor, Canva, and Rippling
• Total funding now at $204M
• Valuation jumped significantly in just 6 months since Series B expansion

What Clay Actually Does: Clay automates the grunt work of sales and marketing ops. Think AI agents that can research thousands of prospects, personalize outreach campaigns, and dig up revenue opportunities humans would miss. The platform pulls from 150+ data sources and can do creative research like monitoring competitor mentions or analyzing satellite imagery to gauge customer fit.

The "GTM Engineering" Angle: Clay claims they've created an entirely new job category - "GTM Engineering" - that bridges sales ops and technical automation without requiring a CS degree. The stats they're throwing around:

• 280+ GTM Engineer positions currently posted at companies like Cursor, Webflow, and Notion
• Median salary of $160K (20% premium over traditional sales ops)
• 7 independent bootcamps have graduated 2,500+ students
• Some GTM engineers have built million-dollar agencies
• Clay's ecosystem includes 108 agencies globally

They expect to generate $50M in revenue for data and integration partners in 2025, while their global agency network represents hundreds of millions in collective revenue.

CapitalG partner Jane Alexander cited conversations with 100+ sales and marketing leaders as validation for Clay's engineering approach to go-to-market operations.
