(Speculative) It seems like biotech VC is doing poorly, and this stems from the fact that it's a lot of work to discriminate good from bad prospects for the biology itself. (As opposed to, say, ability of a team to execute a business, or how much of a market there is, etc.) If this is true, have some people tried making a biotech VC firm that employs bio experts--like, say, PhD dropouts--to do deep background on startups?
