Today, Fireworks announced a $1.505 billion Series D at a $17.5 billion valuation, led by Atreides Management, Index Ventures, and TCV, with participation from Evantic Capital, Lightspeed Venture Partners, Nvidia, 20VC, Bessemer Venture Partners, Menlo Ventures, and others.
This milestone comes as Fireworks surpasses $1 billion in annualized revenue run rate and serves more than 40 trillion tokens every day. More than 95% of those tokens come from models specialized on customers' proprietary data and optimized for specific jobs.
Companies are no longer renting general intelligence. They're building their own.
Every business has proprietary knowledge: customer relationships, workflows, data, and expertise that no one else possesses. That knowledge is becoming its competitive advantage in AI.
Fireworks helps companies transform general-purpose models into specialized intelligence trained on their own data and deliver it at scale on the top-performing inference stack. The result is AI tailored to each business, often delivering frontier-quality performance at a fraction of the cost.
As open models rapidly approach the capabilities of closed frontier models, companies can now own, customize, and improve the intelligence behind their products instead of renting it.
From Cursor's coding models to Harvey's legal AI, companies across industries are building specialized intelligence with Fireworks.
This funding lets us expand our compute infrastructure, grow our engineering team, and continue building the platform that helps companies own the intelligence powering their products and operations.
We're grateful to our investors, our customers, and everyone helping build the future of specialized intelligence. If you'd like to join us on this journey, we're hiring.
