Product
The formula for fixing product problems early.
Synopsis
Most products fail not because the idea was wrong, but because the problem was diagnosed too late. Product is a practitioner's field guide for founders, product managers, and operators who want to catch failure signals before they compound.
Built around a decade of teardowns across African fintech, logistics, and consumer apps, the book distils a repeatable diagnostic loop: uncover the real job-to-be-done, pressure-test assumptions with cheap experiments, and align execution to a single non-negotiable metric.
You will finish with a working playbook — from discovery to launch — and the confidence to kill the wrong bets early enough to fund the right ones.
What you'll take away
- Product strategy
- Problem diagnosis
- Go-to-market tactics
