Co-CEOs, Silver Lake Davidson and Hutchins scored a major payday back in May, when their Palo Alto-based private equity firm sold Skype to Microsoft for a cool $8.5 billion. Eighteen months earlier, Silver Lake had led a group of investors that bought the troubled Internet telephony service from eBay.

After overhauling Skype and closing the Microsoft deal, they walked away with $2.9 billion.
