London Lean is a Meetup to learn, practice and share Lean business practices. By now everyone agrees (I hope!) that ideas are worth the paper they are written on and execution is all that matters, but how do you test your idea on the market with the least possible resources before committing months of hard work to the idea? What are some lessons learned that we, as a community, can share? This meetup is trying to support entrepreneurs and aspiring entrepreneurs that are looking for smart ways to test demand for their ideas.
