Pros

Working alongside of the most grounded and supportive team members you'll find in the tech industry. Great benefits - free healthcare, generous mat/pat leave, personal development and professional development funds. Culture is friendly and the offices are beautiful

Cons

Constant change can sometimes be hard to keep up with. Teams shift around a lot and sometimes there is a lot of ambiguity. PTO is only 20 days instead of unlimited

Pros

A brilliant working environment full of highly talented people.

Cons

None really. It's a very high growth company so there's constant change as we evolve, but I like that.

Pros

Tremendous company to work for. Leadership truly cares about the employee base. Hard work is recognized and rewarded.

Cons

Growing pains. The company has 3-4X in size over the last 2 years. Systems break when any group scales this quickly - but entrepreneurial spirit is encouraged
