Overview
- Fireworks disclosed Thursday that it raised roughly $1.5 billion in a Series D led by Atreides Management, Index Ventures and TCV at a $17.5 billion valuation.
- The Nvidia‑backed startup says it has surpassed a $1 billion annualized revenue run rate and now processes about 40 trillion AI tokens per day, a metric used to show developer usage.
- The company will use the new capital to buy more GPUs, hire engineers and deepen cloud ties, especially with Microsoft and Nvidia, to grow global inference capacity.
- Fireworks positions itself as a lower‑cost inference cloud by hosting open‑weight and third‑party models that customers can fine‑tune on their own data to cut token bills.
- The business still faces concentration risk because Cursor supplied a large share of past revenue and has been agreed to be bought by SpaceX, which could change Fireworks' customer mix.
