Terribly wrong...
Just in fundraising alone YC is such a huge advantage to founders.
Here's an interesting story. I met this pre-seed investor a while ago. During the call he had a terrible superior smug attitude. Never asked a single question, was visible dis-interested and I kept wondering why he even took the call. The call was over in under 10 mins.
2 weeks later the person finds out we're in YC and all of a sudden I saw a total change in attitude. Nothing changed, it was the same metrics, same numbers, same MRR, same team (solo).
And if that feels like an anomaly, it's not. Previously closing any pre-seed felt so incredibly hard. It was as if you're begging. Granted I have no experience doing this and perhaps that was a big part. But those are exactly the kind of founders who have a huge advantage with YC.
After YC, every conversation felt so easy. Most people now wanted to get-in as angels before the YC MFN date kicks in. Checks were wired the same day in many cases after a single conversation.
And if that wasn't enough, here's some more:
1. You're in an ecosystem of startups, many of whom are your potential customers, best friends, confidants and more
2. You're rate of learning in an environment like this shoots up. You learn how your peers are handling things, tips, hacks
3. Advise from the YC partners which might save years of your life doing the wrong thing
I could keep going, but the point is YC is a blessing, and this is a very ignorant take..
