Hahaha, I'm replying to all your comments:
> A good investor would have said to the Homejoy team "we believe in you and will back you in any viable business venture, but the home cleaning market is not a problem that will be solved by technology. Go and find something better and we will talk - here is $50K so you don’t starve in the mean time."
I think the investors think, "Hmm, I don't think the home cleaning market will be solved by technology, but the hell do I know? The last 3 times I said that, I was wrong, and my competitors made hella bank. Screw it, let's do it. They seem smart. They'll figure it out. And if they fail and make something better next time, we have the relationship."
I totally agree with you about the need for prudence, by the way. But I'm not a VC, and I haven't experienced the pressures and challenges that a VC must face. The same "it's easy to judge the man in the arena" idea applies.
