40 Under 40 Fortune Magazines Leaders in Personal Finance

40 Under 40 Fortune Magazine's Leaders in Personal Finance Fortune’s 2016 “40 under 40” list of (relatively) young business influentials hit the web this morning, and a few names stand out from a moneyâ€"and MONEYâ€"perspective. Among the impressive folks included in this year’s ranking, four hail from what you might call the personal finance space. Some are changing the way we think about money; others are changing the way we handle it; and some how we earn it. All are shaking up a piece of the money universe, and we’re transfixed. (In fact, MONEY is so inspired that we’re planning to launch our own list of young personal finance innovators later in the year. Send us your suggestions!) For now, we want to give credit where credit is due. Here are the newly-minted “under 40” leaders shaping the future of finance. Get inspired.
