(Bloomberg) -- Atul Gawande will step away from his role as chief executive officer of Haven, the health transformation effort launched by JPMorgan Chase & Co., Berkshire Hathaway Inc. and Amazon.com Inc., less than two years after agreeing to lead the venture.

Gawande will become chairman of Haven, the group said in a statement. Haven plans a search for a full-time CEO and will be run by Chief Operating Officer Mitch Betses in the meantime. Gawande said in the statement that the change will “enable me to devote time to policy and activities addressing the immediate and long-term threats to health and health systems from Covid-19.”

The high-profile venture was launched in 2018 but has had little visible impact. Its stated mission is to use the immense leverage of the three giant employers to “create better outcomes, greater satisfaction, and lower costs for their U.S. employees and families.”

The Wall Street Journal reported earlier this month that Gawande was in talks about his role at the venture.
