# Fireworks AI raises $1.505B Series D at $17.5B valuation, surpassing $1B annualized revenue run rate

> Fireworks AI has raised a $1.505 billion Series D at a $17.5 billion valuation, one of the larger AI infrastructure rounds of the quarter. Atreides Management, Index Ventures, and TCV led, with existing backers including Lightspeed and NVIDIA returning. The company says it has crossed a $1 billion annualized revenue run rate and now serves about 40 trillion tokens a day, roughly five times its volume a year ago. The business sits in a useful niche. Rather than pushing its own frontier model, Fireworks lets enterprises take general-purpose open models, fine-tune them on proprietary data, and then serve them efficiently in production. Founded in 2022 by six former Meta engineers, it is deepening partnerships with Microsoft and NVIDIA as demand for customized, specialized models grows. The scale of both the round and the token volume is the signal here. It suggests companies increasingly want models shaped to their own data and workloads, not just access to the biggest general system, and that serving those tailored models has become a large business in its own right.
