I would focus on the problem you solve more than the "business model" per se. Unless you're talking specifically about how to make money.
The problem with most startups is that they don't solve an actual specific problem. It's a mobile app for example that does something, but doesn't really address a serious need. It just does something that isn't already being done.
If you add some more color to your question I'd be happy to add some more color to the answer ;)
