Avantages
Great work environment. The technology stack is top shelf. Going to conferences and seeing what other companies in the area are using makes you appreciate the tools we get to use. It is a small company so your ability to influence how the products get built is high. If you show some initiative and the ability to learn things on your own, you can have a significant impact. Adopting newer technologies is never out of the question as long as you can make the business case and come up with an implementation plan. The personalities are great and I've made some good friends during my time here. You can walk into the CEO's office anytime you want and he'll chat about anything with you.
Inconvénients
Small company so don't expect some of the perks that larger companies can offer, like annual bonuses.
