• Full ownership of products makes it easy to ship customer-impacting code.
• Excellent in-house toolkit for building and deploying services.
• Teams are very individualized, and it's easy to move between them.

• Lower base salary than other tech companies; compensation is highly volatile due to stock inclusion.
• Few quality-of-life benefits: no free food or drink, and rare team outings.
• Abysmal 401(k) match.
• Dev hardware is cheaper and less performant than at other companies.
• Teams are very individualized, so it's difficult to assess beforehand how well they will fit an employee.

Invest more in office "life benefits": food/drink, relaxation.

Identify everything that bothers devs more than the projects they're actually working on, and work to alleviate them.
