Most founders obsess over revenue, but at [Your Business], we track 'problem-solution fit' instead. Here’s why:

• Early signal: If 40%+ of surveyed customers say they’d be 'very disappointed' without your product, you’ve got traction (we learned this from the Mom Test book).

• Focuses iteration: We tweaked our onboarding 7 times based on this feedback, reducing churn by 28%.

• Scales word-of-mouth: Customers who score you 9+/10 on 'how well this solves your problem' become natural evangelists.

We built a free survey tool to measure this—no email required. Curious if others prioritize this metric too?
