Gregor Zehetner co-founded Tapkey and exited it. His next company is fully vibecoded: built himself, with Claude Code, now 70,000+ lines of code and 300+ tests, almost none of it typed by hand. That is the proof, not a pitch. Someone who already built and sold a company chose to build the next one alone, because the tools got good enough that domain knowledge became the bottleneck instead of engineering capacity. The evening opens with a quick look at what Founder Institute does, then a 15-minute live demo of launching an MVP from idea to working prototype. Then you get to learn from Gregor first-hand: how he structured the Tapkey exit, why he chose to build Fractionista solo, and where AI-generated code still falls apart.
