Episode notes
What this conversation opens up.
What if your startup raised $2 million… hired a team… launched the product… and still didn’t have product-market fit?
In this episode of The Growth Engine, Mike Parsons breaks down the case of a fictional AI startup that looks successful from the outside — strong founders, funding, and an exciting product.
Recognising these core issues can inspire founders, product leaders, and investors to focus on what truly matters for sustainable growth, empowering and confident in their decision-making.
Using the ProductBooks evaluation framework, Mike walks through the three critical stages every startup must pass before scaling: Problem–Solution Fit → Product–Market Fit → Business Model Fit
You’ll see why this AI company scores poorly on the fundamentals — and why skipping early validation can destroy even well-funded startups.
Along the way, Mike explains the most common mistakes founders make when building products, including: • Targeting an ICP that is far too broad• Building a solution before validating the problem• Competing against giants like Google and ChatGPT without being 10x better• Ignoring willingness-to-pay validation• Confusing early traction with real product-market fit
You’ll also learn how to diagnose the real signals of product-market fit — including retention, advocacy, and the famous rule: Customers stay, they pay, and they pray they never lose the product. If you’re a founder, product leader, or investor, this episode will help you answer the most important question in startup building: Are we actually building the right product?
