Business Model Fit
The inflection a startup reaches when it has gathered enough evidence to demonstrate that it is able to deliver its value proposition with an optimal profit, based on a scalable business model.
The inflection a startup reaches when it has gathered enough evidence to demonstrate that it is able to deliver its value proposition with an optimal profit, based on a scalable business model.
A problem-solution-fit occurs if a startup has proved both: 1) that there is a 'problem worth solving' for one or more clearly defined customer groups, and 2) that there is evidence that these customer groups would consider the value proposition of the solution the firm proposes.
Product-market fit means: you have collected evidence that your solution solves your customers' problem(s) in a way that they prefer over current alternative solutions; you have proof that they are willing to pay for it; and your service demonstrably gains its first traction in the market.
