Probably a fair amount of people (myself included) would like to be an angel investor. For people who are rich but not one-percenters cutting a check for $100,000 for a risky investment is a high barrier to entry. I'd be more inclined to make 10 x $1,000-$2,000 investments (bets?).
Could be interesting for niche markets if it bring in people with expertise, high income and are also decision makers in their day jobs: doctors, lawyers, small business owners, senior managers, corporate officers, etc.
