Pros: From day 1, you're working on something quite important and will be shipped to millions of users. No 20-person committees, endless QA processes, or product counsel in the way. You get to own things end-to-end, and the team pushes you to move faster.

Cons: If you need tons of support and time, you won't be very happy here. Everyone works super hard, and working through weekends isn't uncommon, especially if you're close to a deadline. You're expected to QA stuff yourself, and if things are buggy, all eyes are on you to fix them. As a former founder, this is all familiar, but if I joined a few years earlier, I would've found it really tough. It's also high intensity, as founders are always on.

Pros: High-impact work, lots of learning opportunities, and smart people.

Cons: The office needs to be improved. It could be more social.

Pros: A really exciting place to work, as people are really focused on shipping and delivering great features. Individuals are immediately given lots of autonomy and trust, so people can make a big difference very quickly. Pretty good transparency, as the CEO goes over revenue and numbers each week and encourages people to ask questions. Nice SF office.

Cons: It can be intense at times.
