Disruptive startups can't get funding and there are many people who would like to fund them with small investments of, say, $50.
Here's a solution. Part One: Companies register as public companies on Malta, which is EU, on the cheap (relatively). They aren't listed on any exchange but can privately accept bids for shares from anyone. E.g. 10 shares for $50.
Part Two: A site which offers any company/group/idea the possibility to list (ala Crunchbase) but then for those companies that incorporate publicly in Malta, there's a pre-built mechanism for them to field and accepts bids for equity. There's a very small transaction fee for this.
