I worked at Vivísimo full-time (More than 3 years)
Vivisimo was small enough that you knew everyone, but still large enough to do a decent business. They must have been doing something right, because IBM acquired them in 2012.
If I had to give one negative, it would be that some of the people working there had never really worked anywhere else, so didn't have much experience doing things differently.
Advice to Management
There's no real need to give advice to the management team because they sold the company to IBM in 2012 for a pretty good price, so I guess they knew what they were doing.
