I noticed that too because I was trying to figure out who bought them (Sales Force) on Crunchbase. Entrepreneurs aren't building sustainable ideas. I think this tightly correlates to the series A crunch.
Honestly, I think one of the key things of finding a great investor is not just the money but the business mentorship. With crowd-funding, all you get is money which is cool, but what most start-ups need is money + people in power in their corner to promote their product, set up meetings with corporations who would otherwise never listen to the startup founders, and a way to open doors to new relationships.
