Two observations:

web vs. app data seems to be missing something. According to that graph, about 15% of startups are building either an app or a website. Where are the remaining 85% doing? That sounds strange.

I can't underscore enough the "crystal ball" effect of receiving all those pitches. By hearing every idea out there, you get a free crash course in the future. While founders don't like to hear it, a similar idea has already been pitched 10 times. So investors focus on how you are different from those 10 similar ideas. And often, investors will have "amazing" insights for you, just by repeating what those 10 other founders have told them already. It's like being prescient without being especially smart. A very strange feeling.
