VC here. The comments made about VCs being stewards of other peoples money, and therefore having a different risk tolerance are completely true. There needs to be some solid POC or a well known and trusted team or it is a no-go. But it is not about VCs being dumb finance guys -- some of us are very technical, myself I was a repeat founder and have an advanced technical degree. We invest more money in each deal than angels might in their entire lifetime, and actively help run and scale a company. I certainly have a lot of respect for non-shotgun angel investors, but one is a hobby, and one is a career!
