Pros
The best place I have ever worked and I have worked at some world famous research institutes in the past. I3 is a family first company with well-designed development processes. We work with important customers daily doing meaningful deployments. And we work AT HOME. The family first focus is real, absolutely no questions are asked when it comes to family. For instance, if you have any kid event in the middle of the day, you need just to post your status and go.
Cons
You need to be disciplined to excel. You need to be always learning something new as the CEO is an honest-to-god genius and is always developing new frameworks, new processes and integrating the best new technology into current and future deployments. There is medical and support for buying personal computers but few other benefits other than getting paid a good salary for working in your pajamas!
