Founder OS Assessment.

Workbook + Roadmap.
Built from real experiments.
See how Founder OS evolved from an idea into a working diagnostic system.
Step 01 · IDEA
The first sketch of Founder OS — a way to diagnose founders, not just advise them.
Step 02 · TEST
Founder OS Assessment — the diagnostic questionnaire that produces a Founder Score.
Step 03 · FEEDBACK
Real feedback and result data from early users shaped what the assessment measures.
Step 04 · ITERATE
Multiple versions later — sharper scoring, clearer bottleneck detection.
Step 05 · FOUNDER OS
The live diagnostic platform at founderos.sandboxstartup.vn.
Step 06 · THE BOOK
The complete framework, written down so it can be executed without the platform.
Know where you are before deciding where to go.
Founder OS gives you a free 5-minute assessment that scores your Vision, Product, Execution, Sales and Marketing — then tells you exactly where the bottleneck is.
