There is the list of current Unicorns. I can't think of one of them that doesn't have very, very substantial competition or is a genuinely novel product. All of them ventured into highly competitive, well-worn fields and what set them apart was quality of service, ease of use, and responsivity. Very few of them made conceptual leaps in the underlying product - they mostly made leaps in lowering activity energy to use products or solving associated logistical problems.
Sorry Sam, I have to politely disagree with you on this one. Lord knows you are the one with the resume and authority on this, but I am a startup lawyer and work with clients on this stuff all day, so I am not totally unqualified. I do defer to your judgment, obviously, on companies that you want to fund, and your track record more than speaks for itself. However, what I want to know is if there isn't some disconnect between the companies you do fund and the attitude that is expressed in this post. I would love to hear your insights or opinions on whether you feel that I have this wrong, and if you think that the next generation of unicorns are going to be novel monopolies, or that maybe I am misreading the characteristics of current successful startups.
