#4 Startup Engineering

December 5, 2025 · 00:58:49 · Krisztian Fischer & Toby Sears

Show Notes

In this episode, Toby and Krisztian tackle the challenges of startup engineering, drawing on experience helping companies scale from nothing to tens of developers. They explore the two main startup archetypes: the bootstrapped zero-to-one prototype phase and the well-funded one-to-many scaling phase. Topics include picking the right tech stack, when to use vibe coding versus proper infrastructure, the danger of over-engineering early, unit economics, multi-account cloud environments, avoiding the trap of rebuilding your data centre in the cloud, and why unblocking other teams is always the highest-value activity.
