Sometimes people ask me what I think of their business idea.
When i look at an idea, the first thing i try to find is the problem it can solve? When an idea solves a problem for a particular group of people, it makes it easier to build a business around it.
Here's an example of an idea of a fruit piano that, I have to admit, is cool.
If the idea is cool but not solving a problem, the amount of work to promote it and sell it is generally higher. And it means it's generally harder to turn the idea into a business.
Here's Michael Seibel (who sold its business to Amazon for almost 1 billion dollars) talking about starting with a problem to solve.
