组图：40位40岁以下的商界精英

2. 杰克•多西

•  年龄：36

•  职务：联合创始人兼CEO

•  任职公司：移动支付公司Square

    多西曾经发出了世界上第一条Twitter信息：“我搞定Twitter了”，这也是他构想出分享“状态”的创意。如今，Twitter正在准备进行规模庞大的IPO，而在公司三位创始人中，只有多西仍在Twitter工作。之后，多西又成立了Square（由他本人出任CEO）。如今，这个移动支付系统每年约处理150亿美元。2011年，他开始担任Twitter执行董事长的职务，继续帮助推动重大决策的制定。

2. Jack Dorsey

•  Age:36

•  Title:Co-Founder and CEO

•  Company:Square

    It was Dorsey who shared the world's first tweet, "just setting up my twttr," and conceived the idea to share a brief "status." Now, as Twitter readies its monster IPO, Dorsey is the only cofounder of the initial trio (Biz Stone, Ev Williams, and him) who still works at the company. Dorsey had moved on to found Square, the vaunted mobile-payment system that now processes $15 billion annually (where he's CEO), but in 2011 he added the role of Twitter executive chairman and still helps drive big decisions.
