Pros
Powerful mission. Lots of startups like to say they're making the world a better place. We actually are. Results oriented, flat hierarchy, minimal management. People are largely self managing and motivated. Forgiveness-not-permission culture. Big, challenging problems with big potential and opportunity. *Amazing* people, across science, engineering, product, lab, business, marketing, and more. So many rock stars to learn from! Strong, health business and product/market fit. No office politics!
Cons
Location. Almost but not quite close to SF, the peninsula, or the east bay. Long reach. We need more people to do all the things we want to do. Regulated space. We're actually handling it pretty well, and don't spend too much time on it, but it's definitely a factor. Clinical health care is somewhat slow and resistant to change. Fun challenge though.
