Every company must own its intelligence

More than 95% of those tokens come from models specialized on customers' proprietary data and optimized for specific jobs.<br>Companies are no longer renting general intelligence. They're building their own.<br>The era of specialized intelligence
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.<br>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.<br>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.<br>Building what's next
From Cursor's coding models to Harvey's legal AI, companies across industries are building specialized intelligence with Fireworks.<br>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.<br>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.
