Vantaggi
They are growing and if you are only developing new products, it might be good. There are some nice and talented people who work in the hardware and networking side.
Svantaggi
Scivantage is beholden to one man's vision which is to build new products, get customers to sign ... and then probably retire with all the bonuses he has given himself. He has a few talented IT people, especially his CTO in charge of hardware and networking; however, their coding goal is spin up products fast - if not with good software principles - and "get it out the door." This means that the products are held together with duct tape rather than investing in best practices and re-factoring code. I suspect that any firm that comes along and offers similar products written by more talented developers and a company that actually wants to build quality services will be able to steal clients simply because firms will grow weary of patchwork efforts to keep their products running. If you are a software developer desperate for work, go ahead, but once you see their software architecture, you will understand why few senior developers stick around.
