About

Baseten Labs operates an AI inference platform that lets companies deploy, serve and scale machine learning models in production. It provides optimized model runtimes, autoscaling GPU infrastructure across managed, self-hosted and hybrid clouds, and developer tooling for shipping custom, fine-tuned and open-source models. Founded in 2019 by Tuhin Srivastava, Amir Haghighat, Philip Howes and Pankaj Gupta, it is headquartered in San Francisco and has raised over $2B, including a $1.5B round announced in June 2026.

Pairs in-house performance research on inference runtimes with cross-cloud high availability and forward-deployed engineers, so customers get low-latency, high-throughput serving without managing GPU infrastructure themselves.
