Pluspunten
Please note people confuse these two entities as just Trusted Insight, Inc. TI Platform Management "TI" is a separate legal entity with separate managers. I worked with them for several years as a contractor and my experiences were only always positive. They have a fairly linear hierarchy so not sure about the promote from within comment. The pay is market as far as I could determine. Also, the working from home aspect of TI was great: flexible work schedule, no driving to the office in SF Bay traffic nonsense, no parking hassles, eat from your fridge, so on and so forth... TI lives up to its billing, you can really have a flexible work/life balance working with them.
Minpunten
You actually have to work at TI, but that is what most of us do anyway :)
