A truly entrepreneurial team of indendent thinking personalities.

Disagreement in a diverse and independent team is the key ingredient

In the quest for the best results, disagreement is a good thing. As a team of very diverse and independent thinking personalities, we disagree a lot. We combine the visionaries with the implementers, the finance guys with the sales and marketing people, the experience from legacy with the agility with the new kids on the block. It is always a struggle, oh boy! However, we have always managed to build the right solutions out of the debris of our disagreement. Proper delivery is the ultimate goal, if we haven’t taken a detour, though, apparently things haven’t been thought through.
