A few other thoughts. Nothing about this post says that this group is in the valley. Not all seed investors are in the valley. Not all companies are in the valley. It's a poor assumption to think they are.
Seed investors want a very healthy return on their investment and they want it relatively quickly. You may invest $5,000,000 or $50,000,000 or whatever amount you'd like blindly in whatever increment makes you feel good. But if you don't evaluate the investments you are making, you won't he investing for long. The "Savy Silicon Valley investors" don't invest blindly.
I've been told many times when rejecting a company that I have made a poor choice because of x, y, or z. My reply I'd always the same, "feel free to pull out your own $50,000 and invest. I have plenty of opportunities." I don't mean it to sound snarky. It's just reality. Investors always have processes. This is mine.
