Pros
On the positive side, the company has some awesome talent and great personalities, including marketing and sales guys, the Scrum Master, and about half of the Developers and Designers. Work life balance is good, with moderate flexibility. The owner is incredibly rich and won't run out of cash any time soon. The fitness-gaming product is rather nice.
Cons
Given this is such a small company, it's difficult to speak openly without revealing my identity. Unfortunately, there are also several major downsides.
The office is an open-office, which is incredibly distracting. While the scrum master tries his hardest to keep things organized, requirements change significantly and often. Mentorship opportunities are are nonexistent, and advancement consists of more work without additional perks. Talent is regularly reassigned or TRICKED into to roles they're either ill-equipped for or uninterested in, such as ios/python to java/web, designer to product-manager, game-dev to app-dev, two leads (one had to 'surrender'), and backend to front-end. Three of our best developers left in the last six months, and the talent hired recently is ill-equipped to replace them.
Most recently, several of our devs nearly completed the backend for a major new launch of one of our core products. When the owner saw the placeholder UI, he made them scrap the entire backend, and dragged them into about 4 weeks of meetings where they weren't allowed to code. Worse, the owner's pet names for components make absolutely no sense and contribute to confusion, such as "Reward Scheme" means "how users earn points." That is only one of many examples of terrible and confusing names.
