I looked into investing a small amount in crowdfunding, but there are very few platforms offering it and the companies seemed to be raising money at overpriced valuations. It would be nice if crowdfunding could grow, since ordinary people could get a share of large growth and they could also offer certain unique benefits for a company the raising money (e.g. help with marketing).
