Surely they are way, way less than 10%. I mean tech is less than 10% of the US and the valley isn't the only place for angels. At 1%, which sounds more plausible, we are talking about controlling 50% of deals. That's not an innocuous number.<p>So, screw the 500,000 angels figure. Anyone with any actual knowledge want to tell us how much of the relevant market the top 10 angel firms control?
