Choosing a tech stack is one of the highest-leverage decisions a founder or CTO makes. Pick wrong, and you will spend years paying down debt. Pick right, and your team ships faster every quarter.
The framework we use:
1. Match the stack to your team, not to Twitter hype.
2. Optimize for iteration speed first, scale second.
3. Prefer boring, proven technologies for the core.
4. Reserve the exotic for a single, well-isolated surface.
5. Plan for observability from day one.
In this article we walk through concrete examples across SaaS, marketplaces, and internal tools.
