Some entrepreneurs who have made billions off of their tech ventures like to spend their fortunes in 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 leave all of it to their children.

Tesla CEO Elon Musk
Musk may have five young boys from his first marriage — one set of twins and one set of triplets — but he's already donated much of his $12.9 billion fortune to renewable energy, science and engineering education, and pediatric health.
He signed the Giving Pledge in 2012, committing to donate the majority of his wealth to charitable causes. He receives only $1 a year for his work with Tesla.
Microsoft cofounder Bill Gates
Gates has been open about his decision not to leave his $84.9 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.
Oracle founder Larry Ellison
Even with his lavish lifestyle, Larry Ellison has committed to giving away 95 percent of his wealth to charitable causes, especially to his medical foundation.
"Warren Buffett personally asked me to write this letter because he said I would be 'setting an example' and 'influencing others' to give. I hope he's right," his letter to the Giving Pledge said in August 2010.
Despite committing the majority of his wealth to charity, he also gave his children Oracle stock when they were still babies (and the company was also young). Now that both the stock and company are worth a lot more, he is reported as to wanting to teach them charitable giving too.
