Pros

Great culture of knowledge sharing. People are smart, helpful, curious and overall everyone I've met works hard and means well. Feeling that we're set out to build something great and deeply care about the customer. Oh and you get to properly use Slack!

Cons

Because there's so much growth, sometimes hard to know what to prioritize.
