"I would appreciate a VC where you walk into it and it's a little bit of like the Simon Cowell of VCs." Benn Stancil on The Test Set, explaining why VC feedback is almost always useless — and why radical honesty would actually be kinder. If Simon Cowell tells you you're bad, you're not offended. That's the gig.
