Pros
Best work-life balance I've ever experienced, strong culture of ownership and collaboration, truly a meritocracy where the best ideas win out. Michia, the CEO, is a stellar leader who focuses on empowering people to do their best work. The company as a whole is eager to invest in its people, and the team is filled with smart, fun, easygoing people who I'm constantly learning from.
Kontras
None that I can think of, other than a flat org structure (very common in early stage startups) which may limit advancement opportunities for some, however, the ownership that you get in each role is far beyond what you would encounter at a larger company with more specific linear advancement paths, so the downside is simply a matter of perception for people who are very focused on titles.
