New product teams are a grind, but with the right people, also a lot of fun. It isn't for everyone. When I was hiring for a NPT working on cutting edge tech I told everyone I interviewed they the work life balance was super skewed.

The people who accepted job offers self selected for having a passion for pushing technology forward.

I tried to keep things as sane as I could, but I'd have to go in on weekends and usher people out of the office.

For some people, building cutting edge things is /fun/.
