There exist an Italian version of the Power Map I blogged a couple of months ago. It is pretty interesting to see relationships between business men. There are lots of transactions happening between companies with shared board members. I think that tools like this one should be used daily from the internal revenue services. Below an example of application: I tried to show the connection of Marco Tronchetti Provera, ex CEO of Telecom Italia. At the time he was Chief Executive Officer, he was also in the board of Pirelli Real Estate. He sold many pieces of real estate from Telecom Italia to Pirelli. As Beppe Grillo would say: “He did not even had to call himself to make the deal!”.
