The tool helps startups ensure that their idea will be useful to consumers. It leads entrepreneurs through the process of forming hypothesis about the problem they want to solve, listing assumptions, testing the assumptions, defining success, and then deciding if the assumptions are valid and if the idea is worth moving forward with.
It was created by the company Futurice. The company is based in Finland. We were unable to determine the release date or founding date, however, we did find that the tool was first uploaded to GitHub 4 years ago. One of the founders is Hanno Nevanlinna.
