Pros

- Very collaborative culture - Friendly coworkers - Lots of talented people - Good compensation and benefits - Big focus on work life balance; the office empties out pretty quickly after 5

Cons

- Compared to most tech CEOs, Stewart isn't bad, but I don't think he's figured out how to be really effective at guiding an organization of our size. He still wants to micromanage. - We still write a lot of PhP - Slack is kind of behind the curve as far as using data
