# Baseten Closes $1.5B Series F

> Baseten has raised a $1.5 billion Series F at valuations reaching up to $13 billion, in a round led by Altimeter Capital, Conviction and Spark Capital, structured in tranches at $13 billion and $11 billion. It is an enormous sum for a company focused on a single, increasingly critical job: AI inference. The growth story is stark. Baseten reports 20x year-over-year revenue growth and says it now processes more than a billion inference calls a day, spread across 87 clusters and 18 clouds. That kind of scale reflects how the center of gravity in AI spending is shifting from training models to actually running them for users. The company plans to triple its headcount to chase talent, compute and enterprise sales. As every app races to bolt on AI features, the plumbing that serves model outputs reliably and cheaply is quietly becoming one of the most valuable layers in the stack.
