In the fifth episode of "The Frugal Architect" podcast, Werner and co-host Simon Elisha welcome Morten Keldebaek (CTO) and Robert Hjertmann from Too Good To Go. Too Good To Go is the world's largest marketplace for surplus food, connecting consumers with restaurants, cafes, and grocery stores to rescue food that would otherwise go to waste. The discussion will start with their journey from Endomondo (a sports tracking app) to Too Good To Go, exploring how they applied frugal engineering principles across both startups. They'll dive deep into the technical challenges of scaling a global platform with limited resources, the architectural decisions that enabled their growth, and how their frugal mindset aligns perfectly with Too Good To Go's mission of reducing waste. The conversation will highlight how constraints breed creativity and how asking "why" before building has helped them create sustainable, scalable systems while keeping costs under control.
