What it does
Founders often work on the product when the problem is the market, or credit their own effort for sales the market was handing them. Product-market fit means a product that a real market wants, so the check starts with the market, not with the team or the features. This skill sizes the market and its growth, then looks for pull: orders arriving faster than you can fill them, customers telling others, a sales cycle that is short. It asks whether the team is being credited for something the market caused. If fit is missing, it picks one lever, and it writes the next test and the result that would change its verdict.
You give it
- What you sell, who buys it and roughly how many such buyers exist
- What early customers did, such as orders, repeat buys and referrals
- Customer reviews or messages (optional)
- Sales or usage numbers (optional)
- Customer words (optional)
- Your results (optional)
You get
- A verdict on fit and a score out of 100, with how it was worked out
- Each claim about fit tied to a number or a customer example
- The one lever to change first, and why not the other three
- The next test and the result that would change the verdict
Use it when
- Sales are slow and you can't tell if the product, the pitch or the market is the problem.
- You have some early customers and want to know if that means you have fit.
- You are about to hire or spend on growth and want to know if the base is solid.
