I think what you hear is people trying out ideas to see if they are any good, then building them up if they are. "Obvious" ideas like Tinder are often the result of years of work. You can't do it in a vacuum. We went through this at my previous company, which we sold to a large Silicon Valley software outfit. Even though we had an existing business and could sell product to customers it still took about a year to build a solid presentation to help sell the company itself. At the end we could explain the company value proposition in a few sentences, but that was after talking to numerous insiders as well as a bunch of prospects. It took a lot of practice as well as feedback from many people to get the story right.
