Baseten

AI Inference Infrastructure

The AI inference layer just became the most fundable segment in the entire AI stack — Baseten's $1.5B Series F, split across two tranches at $13B and $11B, reflects surging demand for infrastructure that runs models rather than builds them

$1.5 Billion
Series F · June 22, 2026
Up to $13B Valuation Two tranches: $13B and $11B

Baseten, the San Francisco-based AI inference company, raised $1.5 billion in Series F funding led by Altimeter Capital, Conviction, and Spark Capital, with Sands Capital and Wellington Management as co-leads, plus IVP, Greylock, 01A, Blackbird, Durable Capital Partners, Verified Capital, Battery Ventures, and D.E. Shaw Ventures participating. The round closed across two tranches at $13 billion and $11 billion valuations. Baseten's platform manages GPU orchestration, autoscaling, observability, billing, and developer tooling so companies can deploy multi-model strategies combining frontier models with custom, post-trained models. Revenue has grown roughly 20x year-over-year, with the platform now processing more than one billion inference calls daily across 87 clusters spanning 18 clouds. Customers include Abridge, Clay, Cursor, Lovable, Mercor, and OpenEvidence. Capital will fund tripled headcount, expanded compute, and enterprise go-to-market.
