Eric Lefkofsky, Groupon
Eric Lefkofsky provided $1 million in seed money to Andrew Mason to develop the idea for the coupon buying site. Just a few years later, Lefkofsky and his wife, who are the biggest shareholders in Groupon (even bigger than Mason), got a bump in their net worth when the Groupon IPO popped. According to Forbes, Lefkofksy is now worth around $4 billion—$3.6 billion of which is from Groupon.
