Pros
Stripe is full of highly intelligent and motivated people. They have excellent hiring processes which means you're surrounded by the best and brightest. In turn this has led to them developing excellent products. They also have an inspiring vision to fundamentally change how payments happen, and in turn delivering more value to businesses.
Cons
60+ hours a week are normal at Stripe. Their view is it's a race and they want to win. The main challenge I saw while working there was the company strategy & bets constantly changed (except core payments). It's important to pivot and be flexible, but the frequency with which Stripe did this means a lot of wasted effort planning and re-planning. The founders are exceptional but some of the other leadership hires weren't great, hence a regular rotation at the L team.
