C3.ai, Inc.
A maker of enterprise artificial intelligence software, C3.ai builds a platform and a lineup of ready-made AI applications that large businesses use for tasks like predicting equipment failures and managing supply chains. Tech entrepreneur Tom Siebel founded the company in 2009, initially to help organizations track their carbon footprints. That mission explains the name: "C" stood for carbon, and "3" for measure, mitigate, and monetize.
