AI Build Night: From Idea to App, With a Founder Who Did It Solo

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.<br /><p class="font-claude-response-body break-words whitespace-normal" dir="ltr">Agenda:</p> <ul dir="ltr" class="[li_&amp;]:mb-0 [li_&amp;]:mt-1 [li_&amp;]:gap-1 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1"> <li class="font-claude-response-body whitespace-normal break-words pl-2">17:30 Doors open</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">18:00 Meet the world's largest AI-native company builder</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">18:10 Launch your MVP in 15 minutes</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">18:40 Gregor on exiting Tapkey and vibecoding Fractionista</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">19:10 Q&amp;A</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">19:30 Sundowner on the terrace</li> </ul> <p class="font-claude-response-body break-words whitespace-normal" dir="ltr">Who it's for: professionals with real industry experience who want to test an idea without quitting anything.
