More than a decade later, Internet entrepreneurs are still partying like it's 1999.

Benders in the Hamptons, yachting in the Caribbean, $130,000 bar tabs, and of course, Snoop Dogg.

These geeks turned rockstars spend their days trying to change the world, and their nights partying like there's no tomorrow. As one New York Times tech columnist recently put it, "The newly minted rich are obsessed with outperforming their rivals. One industry party I attended had a jungle theme. This included a real, 600-pound tiger in a cage and a monkey that would pose for Instagram photos."

Sure, there are countless startup CEOs out there who don't feel the need to spray down models with bottles of champagne every weekend. Then there are these guys.

Check out the tech world's 9 biggest party boys:

    Let them eat cake, <i>he</i> said. <a href="" target="_hplink">Yammer</a> CEO David Sacks celebrated his 40th birthday in 18th-century style. His Marie Antoinette-themed bash -- held in the wake of news that Microsoft was buying his social networking company for $1 billion -- <a href="" target="_hplink">cost a reported $1.4 million</a>. Sacks banned social media from the event, but few attendees obeyed the rule, including Snoop Dogg, who performed and then tweeted <a href="" target="_hplink">a picture of himself costumed and holding a teacup</a>.

  • 8. Robert Scoble

    Tech blogger <a href="" target="_hplink">Robert Scoble</a> (right) has <a href="" target="_hplink">openly bragged about crashing tech's most legendary parties</a>.

  • 7. Orkut Büyükkökten

    Known as "Google's chief of fabulous," this talented Turkish programmer knows how to get down. He's been spotted at Burning Man in Nevada, <a href="" target="_hplink">out and about</a> with his former boss, Ex-Googler Marissa Mayer, and he's thrown <a href="" target="_hplink">massive loft parties</a> with strippers, disco balls, indoor waterfalls, and of course, non-stop hula-hooping.

  • 6. Elliott Bisnow

    Bisnow founded the <a href="" target="_hplink">Summit Series</a>, a small group of millenials that seeks to engage "the world's most dynamic dreamers and doers" through high-octane events. Their invite-only gatherings have attracted some big names like Bill Clinton, Mark Cuban and Richard Branson. But when the panels and discussion groups wrap up, the revelry begins. Bisnow's team has <a href="" target="_hplink">orchestrated blowouts</a> in Mexico, Aspen and a <a href="" target="_hplink">three-day Caribbean cruise</a> with yoga sessions led by Russell Simmons, real-life shark-tagging and performances by <a href="" target="_hplink">The Roots</a>. Bisnow's latest plan: Buy a <a href="" target="_hplink">$40 million mountain in Utah</a>, and offer timeshares to the wealthiest members of Summit's community.

  • 5. Eduardo Saverin

    Saverin was <a href="" target="_hplink">double-crossed</a> by Zuckerberg, <a href="" target="_hplink">vilified by Congress</a> and nearly <a href="" target="_hplink">banned from the US</a>. Poor guy. Well, not quite. One of Facebook's co-founders, Saverin is now living the <a href=" /a" target="_hplink">high life in Singapore</a>. The 30-year old Brazilian reportedly glides around town in a Bentley and holds down a a $3,800-a-night VIP table at a local club.

  • 4. Paige Craig

    This former marine now runs <a href="" target="_hplink">BetterWorks</a>, a Los Angeles startup where the so-called "<a href="" target="_hplink">brogramming</a>" phenomenon was chronicled earlier this year. "We got invited to a party in Malibu where there were naked women in the hot tub," one of Craig's employees told <em>Bloomberg</em>. During this year's South By Southwest conference, when one BetterWork's party looked like it was going to have too many bros on hand, Craig reportedly <a href="" target="_hplink">called in nearly 50 UT Austin sorority girls</a>.

  • 3. Ben Lerer

    Lerer may have <a href="" target="_hplink">struggled to pop a magnum bottle of champagne</a> at his startup's 2009 pool party in the Hamptons. But the CEO of <a href="" target="_hplink">Thrillist</a> and partner at <a href="" target="_hplink">Lerer Ventures</a> has had finer moments. Like the time he flew 150 people to Jamaica for a <a href="" target="_hplink">three-day island party</a>, or when he hosted a <a href="" target="_hplink">roof-top event in Miami</a> with acrobats, fire dancers and the Miami Heat's dance team. In short, this former UPenn frat boy knows how to shake off a hangover, somehow splitting time between <a href="" target="_hplink">ridiculous benders</a> and his duties as a CEO and VC. <em>Disclosure: Ben Lerer's father, Kenneth Lerer, was a co-founder of <em>The Huffington Post</em>.</em>

  • 2. Mark Cuban

    Cuban sold his tech startup to Yahoo! in 1999 for $5.9 billion. Back then, during the height of the last tech bubble, <a href="" target="_hplink">dot-com parties were all the rage</a>. Though Cuban has moved to ventures in other industries, he often evokes the spirit of the late '90s tech world with swank, over-the-top <a href="" target="_hplink">soirees</a>. Cuban reportedly dropped <a href="" target="_hplink">$130,000 at the Miami hot-spot LIV</a> the night his Dallas Mavericks won the championship, he's hosted a private <a href="" target="_hplink">Bon Jovi concert at his</a> mansion and he's boys with <a href="" target="_hplink">Lil' Wayne</a>. Enough said. <em>Photo: Director Spike Lee and Mark Cuban arrive at Super Bowl Party hosted by Cuban's HDNet at Victory Park on February 5, 2011 in Dallas.</em>

  • 1. Sean Parker

    What do Snoop Dogg, former San Francisco mayor Willie Brown and Grateful Dead lyricist John Perry Barlow all have in common? They've each made an appearance at a Sean Parker production. Parker's <a href="" target="_hplink">2009 Halloween bash</a> reportedly provided guests with over 100 bottles of Cristal and an abundance of drugs. Another <a href="" target="_hplink">Parker bash</a>, in the summer of 2011, featured stone crabs, cake lollipops and ice sculptures on every table. But even tech playboys get hit with major hangovers from time to time. Back in 2005, after Parker was arrested for <a href="" target="_hplink">cocaine possession</a>, he was <a href="" target="_hplink">ousted as Facebook's first president</a>.
