Founders, what's one technical decision you regret making too early?

I've noticed that early-stage founders often feel pressured to make big technology decisions before they even know whether customers want the product. Choosing a complex architecture, building too many features, or investing in infrastructure that might not be needed for another two years. Sometimes, the smartest technical decision is to keep things simple until the business proves otherwise. But there's a balance. Move too fast without thinking ahead, and technical debt catches up. Curious to hear from founders and developers here. **What's one technical decision you made early that you would do differently today?**
