I build small internet tools and share what I learn along the way—shipping notes, product lessons, and the messy middle. Optimistic about calm, consistent progress.

Why Yibud Exists

I spent years building software before realizing that writing code is usually the easy part.
The hard part is figuring out whether an idea is worth building in the first place.
Yibud is a tool designed to help founders identify risks, assumptions, distribution challenges, and validation opportunities before investing months into a product.
The goal isn't to predict startup success.
It's to help founders validate assumptions and make better decisions before they commit months of work.

Yibud
Most founders don’t fail because they can’t build. They fail because they build the wrong thing. Yibud helps founders identify hidden risks, weak assumptions, distribution challenges, monetization concerns, and validation opportunities before investing months into a startup idea. It helps founders make better decisions earlier and avoid building products nobody wants.
