Stripe

This is the most well-run company I've ever seen. Execution of every detail is taken seriously, from product design to the smallest accommodations in the offices.

The people are simply amazing. Many places I've worked at have a "no a**-hole policy," which is often merely a platitude and, frankly, a low bar to set. Stripe is the first place I've seen that has put such an emphasis on seeking out not only talented but genuinely pleasant people.

The demographic of the company skews quite young. This means driven and (often surprisingly) capable people, but with less collective experience. Senior mentorship is a limited resource here.

Everyone is nice, but sometimes too nice. If you're the kind of person who does their best work in an environment where people are aggressively lighting fires under you and holding you accountable, you probably won't thrive here.
