The venture will be based in Boston and operate free from profit-making incentives, the three companies said in a joint statement.

Berkshire, Amazon and JP Morgan Chase announced in January that they would form a healthcare company aimed at cutting costs for their US employees. The move rattled shares of the healthcare supply chain, including CVS Health and Express Scripts, among others.

Gawande, who is also a bestselling author, practices general and endocrine surgery at Brigham and Women’s Hospital and is a professor at the Harvard T.H. Chan School of Public Health and Harvard Medical School.

In his 2014 book “Being Mortal: Medicine and What Matters in the End,” Gawande argued against prolonging a poor quality of life for the elderly.

Berkshire Chairman and CEO Warren Buffett, who is working on the venture with Amazon’s Jeff Bezos and JPMorgan’s Jamie Dimon, said all the candidates for the job felt they could deliver better healthcare and contain rising costs.

“Jamie, Jeff and I are confident that we have found in Atul the leader who will get this important job done,” Buffett said in a statement.

Buffett has described U.S. healthcare costs as a “tapeworm” on American businesses, hurting their ability to compete with rivals in other countries. Last month, he said the goal is to challenge the entire healthcare industry, not individual segments.

While there is no guarantee the venture will succeed in lowering costs, Buffett said it was well-positioned to try. Amazon, Berkshire and JPMorgan collectively employ more than 1 million people.

“The resistance will be unbelievable, and if we fail, at least we tried,” Buffett said last month.

Amazon’s size and reputation as a disruptor prompted investors to sell shares of companies that might be hurt by the venture.

Several large American employers are getting more deeply involved in managing their workers’ health instead of looking to insurers to do it. Cisco, for instance, last year began offering its employees a plan it negotiated directly with nearby Stanford Health medical system.
