LinkedIn co-founder and Executive Chairman Reid Hoffman is likely to be named to the board of Microsoft once the $26 billion acquisition deal closes later this year as expected, according to several sources. No official offer has been made to Hoffman as yet, due to fiduciary issues, and the many-step process has not been set in motion either. But, if it moves forward as many expect, Hoffman would be voted on as a director at the end of the year, which is when the annual meeting of the Redmond, Wash., tech giant typically takes place. The addition of the high-profile and well-liked investor and entrepreneur would be a coup for Microsoft, which has had an up-and-down relationship with Silicon Valley over the decades. But under CEO Satya Nadella, who replaced the pugnacious Steve Ballmer in 2014, relations have markedly improved.
