MENLO PARK, Calif. and NEW YORK, Oct. 28, 2013 /PRNewswire/ -- Silver Lake, a global leader in technology investing, announced today that Mark Gillett, departing Corporate Vice President for Skype and Lync at Microsoft, will re-join the firm as Managing Director and Head of Value Creation. Mr. Gillett will lead the firm's value creation activities as Silver Lake professionals continue to partner with the senior management of portfolio companies to refine and evolve business and technology strategy, enhance operational performance and accelerate business transformation. Mr. Gillett will succeed Charles Giancarlo, the current Head of Value Creation and a senior technology industry executive. Mr. Giancarlo, who will remain with Silver Lake through the end of the year and then transition into an advisory role, plans to return to a technology industry operating role. Mr. Gillett's appointment marks a homecoming to Silver Lake. Prior to joining Skype, the global communications platform, Mr. Gillett led the firm's value creation efforts in Europe, where he played an integral role in the Silver Lake-led investment in Skype. He joined Skype as Chief Transformation Officer, subsequently taking the role of Chief Development and Operating Officer, and spearheaded the expansion of Skype's global development organization, more than doubling the team of product development engineers. Mr. Gillett oversaw advances to the company's technology platform and global operations by supporting and enabling significant growth in users, engagement and revenue, and subsequently led Skype's integration into Microsoft following the company's acquisition in 2011. "We are thrilled that Mark is returning to Silver Lake," said Managing Partner Egon Durban. "Mark's accomplishments at Skype have transformed the company. He is poised to make a significant contribution to our portfolio companies going forward." Managing Partner Ken Hao added: "We are incredibly grateful for Charlie's outstanding leadership in advancing our value creation strategy for more than half a decade, and we are gratified he has agreed to serve as a Senior Advisor and counselor for our value creation strategies."
