FOR FOUNDERS STUCK AFTER LAUNCH

Your product is live. Traction isn't.

Find out why before you build again.

You've launched. People aren't signing up, sticking around or finding you. Stop Building, Start Validating helps you investigate the real constraint and decide what to test next.

A practical field guide by Joshua Ajieh

THE FIELD GUIDE
FOR WHAT COMES
AFTER LAUNCH.

QUICK FIELD CHECK / 01

What's actually going wrong?

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

You've shipped. Now the signals are mixed.

When traction stalls, every possible fix starts to look urgent.

01Visitors look, then leave.
02Signups don't become active users.
03First-time users don't return.
04Growth depends on one-off effort.

Don't diagnose from a symptom. Investigate the evidence.

THE EVIDENCE LOOP

Observe. Test. Decide.

One way to make the next move more deliberate: learn what is happening, challenge a specific assumption, then decide what the result warrants.

01 / OBSERVE

See what people do.

Find where the journey breaks and listen to the people living through it.

02 / TEST

Challenge one assumption.

Choose a focused experiment that could change your current view.

03 / DECIDE

Make the next call.

Use what you learned to build, change course, scale or stop.

THE BOOK / A FIELD GUIDE

When your startup stops making sense, start here.

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.

The thinking behind the work.

Alongside writing, I work in product management. The portfolio shows how I approach product questions and decisions, including work on Mentra.

WORK WITH ME

Bring the problem you're trying to solve.

If you're facing weak activation, retention or distribution, we can examine what you know, identify what you still need to learn and shape a focused next experiment.

A USEFUL STARTING POINT

Leave with a clearer question.

  • What evidence points to the constraint?
  • Which assumption is most consequential?
  • What small test could change your mind?

EXPERIMENT 001 / FOUNDING RESEARCH

I'm building something for founders stuck after launch. But I'm not building it yet.

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.

Portrait of Joshua Ajieh

JOSHUA AJIEH / AUTHOR & PRODUCT MANAGER

I build products too. That's why I wrote this.

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.

THE NEXT MOVE

What evidence would change your mind?

Begin with the book. Bring a live problem to consulting. Or help shape the next experiment.
