At the beginning, the business model concept exists only as a hypothesis and set of assumptions. In order to check their validity, surveys on customer satisfaction, user behavior, and the long-term efficacy of the concept are required. It is not important whether the initial hypotheses and assumptions were related to the product, the corporate structure, financing, or any other aspect of the startup. This process of gaining knowledge based on data is called validated learning.
On the basis of the validated learning, the business model can be adapted, changed, or even discarded and reimagined – the latter is known as a pivot. The founders of Twitter, for example, initially wanted to focus on podcasts. Only as a result of a pivot did they change their product to cater for short messages with a limited number of characters. The subsequence success of the company is well known.
