Risto Siilasmaa

Risto Siilasmaa, Chairman of Nokia, led the company in one of the most successful corporate reinventions ever. The legendary transactions he helped negotiate in just two years--the purchase of complete ownership of NSN, the sale of Nokia's core mobile phone business to Microsoft, and the acquisition of Alcatel-Lucent--pulled Nokia off a trajectory of certain failure and put it on the path to becoming what it is today, one of the world's most successful global technology leaders.
