Product teams have always faced a cruel arithmetic: the earlier you test an idea, the cheaper it is to change, but the less evidence you have. By the time you have real users, you've already built. Promi's answer is to manufacture customers — not from focus groups or panels, but from the behavioral traces your existing users leave behind. The pitch is simple: feed Promi your session recordings, click data, support tickets, and spending data, and it returns a population of synthetic personas — digital twins — that you can interrogate before writing a line of code. That's a bold claim, and the Y Combinator backed startup knows it. The landing page promises "reliable predictions" and "results in minutes," with heatmaps, A/B tests, and qualitative feedback all simulated. But the deeper story isn't just about speed. It's about whether a model of your customer can ever be trustworthy enough to replace the real thing.
