Every angel investment is "a calculated risk and semi-gamble."<p>Also, title is link bait, considering author doesn't actually provide any reasoning why you shouldn't be funded if you don't have an idea.<p>There are plenty of people I'd rather give money to even without an idea than the average would-be entrepreneur with an idea. A recent example: my friend Tikhon, CEO of Parse, raised money and started his company before they thought of the idea for Parse. I'm pretty confident my investment in Parse is going to make me a bunch of money, given their skyrocketing growth.
