Pros
We're living the start-up dream. We're a small, nimble company that has the potential to make a big impact on people's lives. First, I truly believe in the mission of the company - "help people make informed decisions about where they work." Work is important - it's where many people spend the most time, your salary has a big impact on the freedom you have in your life, etc. So helping people make good decisions about their work is important and valuable. Second, the work environment is great. People respect each other. Each person truly contributes to making the company successful. Management (which I'm part of) is extremely open about how decisions are made and what our goals are. And there is a great energy that comes from everyone working together to achieve a shared vision. We respect the importance of having balance in your life. We work hard, but people can always take time off when they want/need to. Often times people work extra but it's because they are excited to deliver results rather than because it's required. And, people are compensated fairly. We have good salaries, extremely generous equity package and great benefits...especially for a startup - what startup do you know that had a 401K in the first year it existed?
Kontras
We're prone to many of the drawbacks of a startup. Career opportunity is limited - with a 11 person company, there isn't a lot of room for promotion and taking on more senior roles. However, that is balanced with the opportunity for every person to have total ownership of his/her work and to play many roles so it's a great place to learn and grow. There's also risk in a startup. We're fortunate to have enough capital to build the business, but any startup is riskier than an established company.
