Hi PH — I build small games/simulators about business reality (and I keep testing AI's edge cases)

Hey everyone — Sergey here.

Short version: I like turning messy business problems into playable systems. My first product here was UnitGame, a unit-economics simulator that makes SaaS math feel like a game instead of a spreadsheet. Small, but it taught me more about pricing and churn than any course.

Right now I spend most of my time poking at AI agents and asking the boring question everyone skips: "where does this break in production?" Long-running jobs, retries, who-pays-for-what, that sort of thing. I'm less interested in demos and more in the failure modes.

I'm here to learn from what you all ship and to give honest, non-generic feedback on launches — especially anything touching pricing, retention, or agent reliability.

What's the one failure mode in your product you wish more people asked about? Curious to hear what people are actually dealing with.
