Pros

- Very supportive environment to learn and grow. - Few "rock star" types, so they don't ruin the culture. - Family friendly

Cons

- Because the company is a little more conservative, it doesn't have all the perks other start ups have (for example, food). - Having tenure gives your words a little more weight than it should

Pros

Individuality is not only welcomed, it is celebrated. The company focuses strongly on diversity not just of ethnicity, but of age, background, identification, beliefs, and just about anything you can think of! There is a very open and transparent culture, as you can imagine from a company that makes a tool specifically for communication and transparency. Sometimes I find myself so comfortable in my surroundings that I have to actually remind myself that I am, in fact, at work, and need to act as such. But it's just such a friendly and warm atmosphere filled with brilliant and funny people.

Cons

It's a startup, so long hours can be expected if you are not a programmer.
