CLASS OF 2013

Patrick and John Collison THEN:

Irelandborn brothers Patrick and John dropped out of MIT and Harvard to cofound Stripe in early 2010 at ages 21 and 19, respectively. They came up with the idea for accepting credit cards on the web while on vacation in South America.

NOW:

Stripe is the secondmost valuable U.S. startup, worth

$95 billion; the brothers each own a $9.5 billion stake. Patrick, its CEO, is diversifying Stripe to include crypto and tax collection tools, among others, ahead of a muchanticipated IPO.

Rihanna THEN:

The 24yearold pop star had secured endorsements with Vita Coco, Nivea and perfume Reb’l Fleur.

NOW:

Rihanna is a billionaire, thanks to Fenty Beauty, her 50/50 joint venture with LVMH. The brand, which makes skin color–inclusive products, is worth an estimated $2.8 billion. Her JayZbacked Fenty lingerie brand raised money at a $1 billion valuation in February.

Zhang Yiming THEN:

He founded ByteDance in 2012 in a fourbedroom Beijing apartment and launched newsaggregation app Toutiao months later.

NOW:

ByteDance’s roughly fiveyearold app TikTok has more than 1 billion users worldwide, but its future will be in the hands of someone other than Zhang, who stepped down as ByteDance’s chairman in November as the Chinese government exerts more pressure on highprofile CEOs.
