Apparently Weebly took YC financing after being featured on TC. I am pretty sure this creates a different mentality from the investor perspective, YC included. If YC finances a rising company, as opposed to paper-idea company, they have a much better look at how the market is reacting; would it be fair to say that in this way, it is much easier to spot potential successes, and fund very much in the style of a normal VC, as opposed to early stage seed funding? I would assume so. And if that's true, is it fair to say the Weebly would've done equally well without YC funding, and directly went for larger investments? Or was YC the stepping stone for that? And if so, how?
