Pros
I've worked at Reltio for the past two years. It is a fantastic place to work, a little informal in some regards, but that honestly makes for a friendlier and more open work environment. The management is engaged with both the product and the workforce, and the CEO - Manish Sood, is open and friendly to all. I prefer to come into the office most days, but they are flexible about working remotely. They place a great deal of trust in their staff, and have high expectations, but it's ultimately a very rewarding place to be.
Cons
None I can think of, things have been getting better all the time.
