Hah what a similar story to my own - open source, Stripe then into YC. The energy at Stripe was unreal and I’m not sure I fully groked it until I started my own business.<p>> Everyone I talked to genuinely cared about their job and about me as a person, and everyone was high powered.<p>Simply walking around the office(s) was incredibly energizing for this reason. Fairly hard contrast with the last year of isolation and working alone! “Figure out what great looks like” is great advice, but I will say it does generate some imposter syndrome that I hadn’t felt before Stripe and YC, for (probably) better or for worse. Capitalizing on these experiences without getting caught up in comparison paralysis is a genuine skill that you seem to have mastered. Congratulations on the funding!
