Besides the labs, Fortune 500 companies and startups use the platform. Revenue is growing fast, and the company is scaling profitably to keep up with strong demand. Its roughly 15 people, most of them working full time in person, include four International Olympiad medallists, serial AI startup founders and researchers published at venues such as ICLR and NeurIPS.
