Is C3.ai a real company?

I'm curious to know, is C3.ai a legitimate and established company in the tech industry? I've heard about their AI and machine learning capabilities, but I'm wondering if they're just another startup with big promises or if they've actually proven themselves in the market. Can you provide some insight into their track record, reputation, and any notable achievements or partnerships they've secured? I'm interested in understanding the credibility and potential of this company before considering any investment or collaboration opportunities.
