From a Blank Chat to a Product You Actually Use

Dejan starts with a hypothesis and a blank chat. One hour later there's a live product, and it's on your phone, built in front of you with nothing hidden. Partway through it breaks on purpose, because AI doesn't crash when it's wrong, it fails confidently, and the moment you catch that is the moment you learn what actually has to be true before anything ships. You leave with the product, the prompt that made it, and the guardrail that saved it.

What you'll walk away with:

1. Your hypothesis is the product, not a deck. See a bet turn into something real and usable before anyone writes a spec, so you learn whether it holds before you commit a team to it.
2. Test before you ship, because AI fails quietly. AI doesn't crash when it's wrong, it's confidently wrong. Catch the moment it does something it shouldn't, and stop it with one rerunnable guardrail.
3. You leave with the product and the tools to build the next one. The live product you used, the prompt it was built from, the guardrail test that saved it, and the method written down. In your inbox before the session ends.
