Hey Bryan,
As Patrik pointed out, it's actually about crowdfunding (not venture funding), none of those start ups that I wrote about were initially venture funded, they were funded by people like us interested in crowdfunded science (just as as side disclaimer I backed all three with a donation as I want to help foster further growth in crowdfunded science).
Additionally, it's all DIY as the groups doing it are doing it themselves and outside of academia and a classical corporate structure (although I'm assuming they eventually incorporate to functionally operate). So any thoughts on what's next?
Best,
R
