Alessia Paccagnella quit a "perfect" job, walked away from a stalled biotech pivot, and rebuilt her future inside Y Combinator with Vibeflow.
After two failed ideas, three YC applications, and zero safety net, Alessia and her co-founder realized the current wave of AI builders was hitting a wall: frontend magic, backend chaos.
Vibeflow emerged from that frustration. It’s a visual backend editor that offers deterministic code generation, giving non-technical founders a way to finally understand and control the logic of their apps without relying solely on black-box prompting.
We dig into why vibe coding breaks at scale, how visual backends solve reprompt hell, and what the Y Combinator pressure cooker was really like from the inside.
The Backend Gap: Why AI builders fail on integration layers and get stuck in reprompting loops.
Visual Control: Moving from LLM hallucinations to deterministic node graphs.
The Pivot: Shifting from microbiome deep tech to developer tools in just weeks.
The YC Journey: Three attempts to get in, the reality of the program, and building under extreme constraint.
Viral Launch: How honesty and "building in public" drove a #1 Product Hunt launch.
Backend Reality Check: Non-technical founders need visibility, not black boxes.
Determinism Wins: Node graphs that map directly to backend code eliminate hallucinated logic.
Prompting Isn’t Enough: Maintenance and scalability break without visual structure.
Speed Requires Sacrifice: Quitting the safe job is often the necessary inflection point for growth.
The Future of Vibe Coding: Human-in-the-loop control remains essential for production-grade software.
Vibe Coding is a podcast about building software and reality with AI. We dive into what actually works, share practical techniques, and talk to the people building these tools.
