In 1989, Behring co-founded Modus OSI Technologies, a technology company. He remained a partner in the company until 1993, contributing to its operations in both Florida, United States, and São Paulo, Brazil. From 1994 to 2004, Behring was a partner and board member at
GP Investments, the largest private-equity firm in Latin America. During this period, under the mentorship of billionaire Brazilian financier
Jorge Paulo Lemann, Behring gained experience in investing, mergers, and acquisitions. In 1998, Behring co-founded
América Latina Logística (ALL), a private sector railroad company. He was the CEO, overseeing the company's operations in Brazil. Under Behring's leadership, ALL experienced significant growth, with its public market capitalization increasing fortyfold compared to its acquisition price by GP Investments a decade earlier. In 2004, Behring co-founded
3G Capital, as the managing partner. He was sole managing partner until 2019, when he promoted
Daniel Schwartz to co-lead the firm. The firm originated from the investment office of Jorge Paulo Lemann, Carlos Alberto Sicupira, and Marcel Herrmann Telles. In 2014, Behring played a pivotal role in the merger of Burger King and Tim Hortons, which formed Restaurant Brands International. Warren Buffett, through Berkshire Hathaway, was a key financier in the transaction. Reflecting on this collaboration, Behring noted, “When I called about merging Burger King with Tim Hortons, he jumped in with sharp insights from decades of prior study of the business. That taught me the power of compounding knowledge.” He was chairman of
Kraft Heinz from 2015 to 2022, having previously been chairman at the H.J. Heinz Company since 2013 for which he led 3G's 2013 acquisition of Heinz alongside Warren Buffett's
Berkshire Hathaway. Behring was on the boards of
Anheuser-Busch InBev,
CSX Corporation, and
Hunter Douglas, joining the latter in 2022. ==Personal life==
