To me, there are two big questions for this burgeoning boom:

1. How on earth are these platforms going to police fraud, as the JOBS Act requires them to do? Considering that we’ve seen fraud at start-ups backed by sophisticated venture capitalists (see: Canopy Financial, Terralliance), do we really expect crowd-funding platforms to have the capacity to dig into their clients’ potential problems?

Moreover, what happens to trust in the broader movement if isolated frauds do occur? Will crowd-funding prove popular enough to withstand news stories about little old ladies who lost thousands of dollars to an unscrupulous “entrepreneur?” The per-deal investment limits may help mitigate the damage — no accredited investors will lose their nest egg on a single company — but each of these platforms should pay very close attention to the due diligence that their rivals are, and aren’t, conducting.

2. What is going to differentiate the platforms? Maybe there will simply be so much volume that more will be merrier, but there will need to be incentives for startups to pick one system over another.

That’s why I wonder if one of these platforms will team up with a well-known angel investor, who would publicly co-invest on certain deals. Kind of like the social recommendation model that has made AngelList so effective, except with transactional capabilities. For the angel, the carrot would be the ability to quickly line up co-investment for new portfolio companies – likely becoming a super-angel without all that messy fundraising….
