Wherever I read about startup pitching, there is a strong emphasis on the "problem that the company solves". In fact, it is often cited as the #1 point to address.
Yet, many technology advances do not really solve a problem but create new use cases, or improve on existing things.
In these cases, what's a pitch that works? I don't think that "imagine a world where..." works very well...
For instance, how would you pitch the creation of Nintendo? Or Facebook? Or Visicalc?
None of these cases solved any particular problem, yet, they clearly have been massively successful.
