Georgios Diamantopoulos
Zero to MVP, Greece, Athens
Georgios has spent 16 years building software in startup environments, always the one responsible for making the technology work — and always cleaning up what happens when speed beats judgment. In 2019 he co-founded Zero to MVP, where his team has shipped over 25 products that can pivot and scale. Lately, a new kind of project keeps landing on his desk: vibe-coded products that look great, work on the surface, and are quietly falling apart underneath. He's been untangling AI-generated codebases and figuring out what constraints would have prevented the mess in the first place. He speaks internationally about pragmatic engineering, developer health, and what happens when we hand powerful tools to people without guardrails.
