Pros

- exciting business opportunity with tons of upside still ahead - very smart people to work with and learn from - good diversity of backgrounds and experience - no jerks, lots of respect and empathy for co-workers - opportunity to create and build something amazing - everyone has a hand in creating the business and helping determine its future - worklife balance is real here for everyone, including parents

Cons

Few to mention here... - too open? Sometimes conversations about small topics will take center stage in the internal news cycle which can be a distraction from the work at hand. - Life is great here and wouldn't trade it but it feels like we may be a bit over-entitled at times. It's not outrageous, but can be a little silly at times.

Pros

Pros -Culture is strong, and there's a lot of passion for the product. -Co-workers are very friendly and helpful. -The company itself is very successful and continues to grow on that path.

Cons

Cons -Some of the leadership is a little under-qualified, and it shows. -Benefits could be better, but maybe that's why we still have so much money left in the bank? Catch-22 situation. -There's a distinct lack of transparency as we continue to grow larger, and it's unfortunate because that was not the case in the beginning.
