Before PayPal and Slide founder Max Levchin moved from Illinois to Palo Alto in 1998, he'd started three companies and sold the last for $100,000 — not a tiny amount of money, especially for a young entrepreneur. But after selling PayPal to eBay for $1.54 billion, these days Levchin is worth around $100 million. Six figures no longer merit that much of his attention. It's such a paltry amount that in Once You're Lucky, Twice You're Good, Sarah Lacy reports Levchin actually forgot about the money until 2006. "In just four years," Lacy writes, "$100,000 would go from being unfathomable riches to pocket change." Levchin is no longer interested in the purchasing power of money, but we are. So let the young multi-millionaire know how he should spend that $100,000 in "pocket change" in our poll.
