Since retiring as CEO of Microsoft in 2014, Ballmer has ramped up his philanthropy, writing checks to his and his wife’s alma maters (Harvard and University of Oregon, respectively) and putting $1.9 billion into a donoradvised fund at Goldman Sachs. He has also put together a website called USAFacts.org for people to look up and understand where the government is spending money. Ballmer, who met Bill Gates (No. 2) while they were classmates at Harvard and became Microsoft’s 30th employee, owes most of his fortune to the software company. He owns the NBA’s L.A. Clippers, which he bought for $2 billion in 2014.
