Afterpay • $1.8 billion

In 2014, then-24-year-old Molnar (above right) was living with his parents in Sydney, Australia, selling jewelry on eBay, when he joined his neighbor, former investment banker Anthony Eisen, to launch Afterpay. Today they’re co-CEOs of the publicly traded pay-later company that’s worth some $22 billion. Afterpay has more than 16 million customers in the United States.
