Pros
It's great to work at a company whose mission I really believe in. The leaders of the company really want to change health care. The product really gives consumer crucial information to make better health care and financial decisions. The quality of the product is first rate and I can say that product and engineering are always asking the right questions about how to make the product better for the consumer. Finally, the people are first rate. The quality of work is very high. It hires really smart people who are also good people to work with. We are in early stages of the company, but I believe Castlight could become a very special place.
Cons
People work hard so hours can be long but the goal is to create an environment that people will stay long term so there are a lot of checks to that. As start-ups go it's not the most "fun" place. It's more on the professional side rather than a bunch of 20-somethings so if you're looking for that...
