Some entrepreneurs who have made billions off of their tech ventures like to spend them in some pretty extravagant ways, whether it be on private planes, summer homes, or even an entire island.
Others turn to more-philanthropic efforts, choosing to donate their wealth to different causes through foundations and trusts.
We've rounded up some of the most generous people in tech, all of which have decided to donate large portions of their wealth to charity rather than pass it down to their children.
Microsoft cofounder Bill Gates
Gates has been open about his decision not to leave his $78 billion fortune to his three children. They will reportedly inherit just a small slice, about $10 million each.
"I definitely think leaving kids massive amounts of money is not a favor to them," he said in a Reddit AMA in February.
He founded the Bill & Melinda Gates Foundation in 1994, and it currently has more than $36 billion in assets. Gates also teamed up with longtime friend Warren Buffett to start a campaign called "The Giving Pledge," which encourages other billionaires to donate at least half of their fortune to charity.
AOL cofounder Steve Case
Case helped millions of Americans get online, and now he's donating much of his wealth to developing other technologies.
He founded the Case Foundation in 1997, which focuses on using technology to make philanthropy more effective. He also started an investment firm called Revolution, which invests in startups outside of Silicon Valley, and signed the Giving Pledge.
"We share the view that those to whom much is given, much is expected. We realize we have been given a unique platform and opportunity, and we are committed to doing the best we can with it," he and wife Jean wrote. "We do not believe our assets are 'ours' but rather we try to be the responsible stewards of these resources."
Salesforce CEO Marc Benioff
Benioff recently launched a campaign called SF Gives, which challenged tech companies to raise $10 million for San Francisco-based nonprofit programs in just 60 days.
He's encouraged other corporations to follow his 1/1/1 model, which says that a company should donate 1% of its equity, 1% of its employees' time, and 1% of its resources to philanthropic efforts.
He and wife Lynne have also personally given a total of $200 million to the children's hospital at UCSF.
