Pros
Management is genuinely doing their best to make the best decisions for the company they can. And they're smart enough that their best doesn't miss much. The bar for consultants is unapologetically high and there is motivation to impress as you employees are surrounded by impressive consultants. I just read through these reviews and, if I wasn't part of the company and didn't know better, I'd suspect there was a company drive to manipulate this site. But there isn't. Or if there is, then it happened very much on the sly. Appirio is a great company to work for. If you're exceptional you'll be recognized. If you're growing then you'll be working in fertile soil. If you get an opportunity to work here then you can consider that you are doing your career a favor. The company is still small enough that exceptional people get noticed at all levels of the organization and you'll get to work on interesting and varied projects.
Cons
Some things don't go the way you want them to. But that happens everywhere. Processes are still being worked out. Be a part of that but expect that not every step will be a step forward. But again, that fact comes with all companies open to process optimization.
