Pros

It's so amazing being part of changing the way work happens. The talent here is so innovative and thoughtful, really trying to engineer the best solution for the world's needs, not just create arbitrarily. The company is still small enough that you can wrap your hands around multiple projects while really focusing down into the details on a few. The culture is amazing, such an open and accepting environment, a sense of community, and really embracing diversity and change to make the world a better place. We also use our own product to support this community experience across the whole company, not just HQ, really making it a team both online and IRL.

Cons

Growth is hard. We're growing fast and sometimes change can get in the way of the big picture, but it's a great time to get in to influence that growth. No insurmountable challenges.

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
