# Fireworks AI Series D: $1.5B at $17.5B Valuation

> Fireworks AI has raised a $1.505 billion Series D at a $17.5 billion valuation, led by Atreides Management alongside Index Ventures and TCV. The company runs an inference platform that lets businesses fine-tune and serve their own specialized AI models rather than relying on a single general-purpose system. The raise lands alongside a revenue milestone: Fireworks says it has crossed $1 billion in annualized revenue, roughly five times where it stood at its previous round. It reports serving more than 40 trillion tokens a day, and says about 95% of that traffic comes from customer-specialized models rather than off-the-shelf ones. That mix is the interesting bit. It suggests real demand for tailored, smaller models tuned to specific tasks, a counterweight to the assumption that everything runs through a handful of giant frontier systems. For the infrastructure layer that keeps those custom models fast and cheap to run, that is a large and growing market.
