Pros
If you are a self-starting, self-directed worker, the all-remote, work-anywhere structure is a dream come true. Work where you are. It's refreshing to be at a company that is really trying to experiment with the future of the workplace in a meaningful and systematic way. The product is incredible, and aggressive/visionary product development is ongoing. No resting on laurels here! Employees are welcoming, friendly, and apolitical. Everyone is trying to get things done.
Cons
If you struggle with being remote, it probably won't be your cup of tea. As a rapidly growing software startup, all of the normal stresses and strains are present. Things move fast, and you work hard. Systems are being built in earnest across the company. Nothing atypical for a rocket-ship startup, but, again, not everyone's jam.
