'In a nutshell, we concluded that it made the most sense to have Greg spend less time on management and more time on investments and that we needed to bring in an exceptional co-CEO with a strong tech focus to supplement the existing leadership,' Dalio wrote. When Dalio announced the recruitment of Rubinstein and Jensen's giving up of the role of co-CEO, he argued, without directly referencing it, that a Wall Street Journal report from February mischaracterized a dispute between him and Jensen, and that the hiring of Rubinstein was already in the works when they were settling a particular disagreement. He was assured that Rubinstein could thrive in this culture because Rubinstein spent the 1990s and early 2000s as one of late Apple CEO Steve Jobs' top executives, and Jobs is remembered for his brutally honest management style.Īnd Rubinstein's long tech career, which includes a key role in developing the iMac and iPod, is a perfect fit for Bridgewater's reliance on increasingly sophisticated automated trading software.
