Fireworks targets enterprises that need to turn proprietary knowledge, workflows, and data into specialized intelligence instead of renting only generic models; the company says more than 95% of its over 40 trillion daily tokens come from models specialized on customers’ proprietary data. The funding matters because Fireworks reports more than $1 billion in annualized revenue, more than 10,000 customers by October 2025, and a $1.505 billion Series D, backing its bet that production AI will shift toward customized models that are faster and cheaper to run.
