What problem are you trying to solve?

I recently had a talk with someone who was speaking about all these
cool ideas for companies, most of them Web 2.0. At some point, I had
to stop him and ask “What problem are you trying to solve?” He looked like I just didn’t get that “when you take X and marry it with Y, you get Z and that’s AWESOME.”

I told him that I understood wha the was saying, but that I just didn’t get what problem he was trying to solve with it.

Mashups, new ideas, and Web 2.0 are cool, but the core question any
business should be able to answer is “What problem are you trying to
solve?”. It doesn’t matter how cool your idea is, if it doesn’t solve
someone’s problem, you’re inventing a market and that’s tough to do. It’s even tougher to invent a market, and convince people that you’re the best company in that market at the same time.
