Corporate giants’ joint venture ends

A health care venture conceived by Amazon, Berkshire Hathaway and JPMorgan to attack soaring costs is dissolving.

Haven, which was formed in 2018 by the three U.S. corporate giants, will cease operations by the end of February, a company spokeswoman said Monday. She gave no reason for the dissolution of the venture.

The independent company was created to focus on improving the care delivered to employees of those businesses while doing a better job of managing the expense.

But the Boston-based venture has been largely silent since naming a high-profile CEO — Harvard professor, author and surgeon Dr. Atul Gawande — and then announcing its name in 2019. Gawande departed last May.
