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

Pros

Coworkers are smart, kind, and supportive. Good product. Interesting problems to solve.

Cons

Culture has lost its way a bit under Salesforce. Tight budget, hiring freezes, and tight ACV goals and deadlines have changed priorities across the company for the worse. Stock isn't doing well.
