I think there is big potential value in a new exchange that optimizes for cheap IPO'ing rules. Something between Nasdaq and Wefunder. I'm not persuaded by some of the ideas they have (like adding diversity to their governing board, seems designed to be exclusive to tech-startups that already have a bias toward that "value"). But if only by competition they make listing cheaper and easier it could have a big impact.
