In a startup, both the problem and solution are unknown.

Zero invites imagination, but small numbers invite questions about whether large numbers will ever materialize.

Using the Lean Startup approach, companies can create order not chaos by providing tools to test a vision continuously.

Entrepreneurs always pitch their idea as 'the X of Y,' so this is going to be 'the Microsoft of food.' And yet disruptive innovations usually don't have that character. Most of the time, if something seems like a good idea, it probably isn't.
