This an interesting framing. I've had this experience. Once I was running a failing funded startup and was really in the seller position because I felt like I needed the board's position to keep running it.
But I think underlying that was an insecurity about failure. If I could have accepted that we were failing then I could have been a lot more confident in bringing a buy mindset: I'll only keep running this if we all are committed to it.
In contrast, I had that buyer mindset from the beginning with this job. I interviewed on the idea that I wanted to focus and be here for the long run. I negotiated strong for long term incentives and avoided accepting short term incentives.
So the dynamic is that I have a lot of confidence in my support. If they didn't want to focus they wouldn't have hired me. And if any owner wanted to make a short term decision they'd have to first start by renegotiating my incentives.
In contrast, this job has a much, much better feeling.
