How tech titans live: From California mansions to a Hawaiian island: The stunning homes of the top 25 web moguls revealed

These 25 tech moguls have laid the foundation for the future, building their own vast fortunes and picking up some serious real estate along the way.



Their homes range from 'modern castles' to entire islands, some even boasting tell-tale technology nicknames like 'Raptor Residence' or Bill Gates' 'Xanadu 2.0'.



And as their industry booms, skyrocketing sales in Silicon Valley are sure to put pressure on these moguls to spent even more on their home sweet homes.



In the last few months alone, several of the stars of the scene have purchased new residences with their bulging bank accounts.

Zynga CEO and cofounder Mark Pincus scored a $16million San Francisco mansion, Oracle CEO Larry Ellison purchased the entire Hawaiian Island of Lanai for $600million and Netscape cofounder Jim Clark bought an estate on Southampton for $49million, according to Business Insider.

The desire to build bigger and better near the business center of Silicon Valley has caused sales to skyrocket, according to NBC.



Currently leading the nation in the number of homes sold for $1million or more, sales of the pricey properties have more than doubled in the past year alone, according to Realtytrac, beating out luxury leaders like Beverly Hills and Miami.



Not all media moguls reside in the Valley, but several do stay true to form.
