QUICK FIELD CHECK / 01
Choose the pattern that feels closest. This gives you a starting question, not a diagnosis.
SYMPTOM → QUESTION → EVIDENCE
WHAT'S HAPPENING WITH YOUR PRODUCT?
THE PROBLEM
When traction stalls, every possible fix starts to look urgent.
Don't diagnose from a symptom. Investigate the evidence.
THE EVIDENCE LOOP
One way to make the next move more deliberate: learn what is happening, challenge a specific assumption, then decide what the result warrants.
Find where the journey breaks and listen to the people living through it.
Choose a focused experiment that could change your current view.
Use what you learned to build, change course, scale or stop.

THE BOOK / A FIELD GUIDE
Stop Building, Start Validating is for founders who have already made something real and want a clearer way to make sense of weak traction. Follow the questions, look for stronger signals and choose a next step you can defend.

EXPERIMENT 001 / FOUNDING RESEARCH
I'm speaking with founders about how they discover what blocks traction and decide where to focus. Your experience can help test whether there's a useful product to make.
This is an early exploration, not a finished product or a promise of access.

JOSHUA AJIEH / AUTHOR & PRODUCT MANAGER
I've seen how easy it is to confuse shipping with learning. I wrote this book to help founders ask better questions when the product is live and the answers are still unclear.
