Someone pasted client data into ChatGPT. The output was useful. They shared it internally. Nobody thought much of it… until six weeks later, when a client asked why their info showed up somewhere unexpected. Then came the scramble: Which tool, which model/version, who did it, what data went in, what the output said, where it spread? The worst part is, most of it was unrecoverable. What they had was a support ticket, scattered email threads, and no clean answers. This is what AI risk looks like in most companies. The risk only becomes visible when someone starts asking questions. What they need is a record, an on-chain evidence that exists before anyone knows to ask. That’s one of Number's role in AI industry: audit infrastructure for AI outputs. When’s the last time your company audited what AI tools employees are using?
