I& #39;ve operated startups for 10+ yrs and I still remember the single most useful feedback I ever got:

I& #39;m doing a sales mtg for Invite Media and our angel investor joins to listen. After the meeting he pulls me aside and said:

"You are the worst fucking salesperson I& #39;ve seen."

That was eye opening. And amazing, brutally honest feedback.

I am a lot better now at sales.

Because I was told honestly that I sucked and needed to get better.

So I& #39;m going to try to be that kind of angel investor and tell founders they suck when they suck.

(and then explain why and how to get better...obviously)
