I’ve had the privilege to invest one way or another in about 20 SaaS companies — half as a VC, half as an individual / advisor / angel. It’s a pretty solid group and I’ve learned a lot from it.
One experience that confuses a lot of founders is when it really starts to take off — I mean, when it’s really now clearly good — and they still get “No”s from VCs. They understand why they got “No”s in the early, pre-traction days, and even, in the early-ish days when they had a handful of customers but wasn’t really taking off yet (my favorite time to invest).
