While much is still unclear on what a healthcare venture formed by three high-profile U.S. companies will accomplish, it at least now has a name.

Boston-based Haven, formed by Amazon, Berkshire Hathaway and JPMorgan Chase, unveiled a new website this week with a letter from CEO Atul Gawande, formerly a surgeon at Brigham & Women’s Hospital. First announced last year, Haven says it will be a patient advocate and ally to anyone — industry leaders, clinicians, policymakers, innovators and others — who "makes patient care and costs better.”

The healthcare startup also promises to work to change policy, contracts, technologies and systems to improve healthcare.

Haven will be based in Boston, but it will also have an office in New York City, the Boston Business Journal reports. Technology and data are expected to play a crucial role in Haven’s operations, as the company is recruiting data scientists, clinicians and software engineers.

Before a rollout to the general public, Haven will initially focus on the 1.2 million U.S.-based employees of its three founding companies.

“As a surgeon, I’ve devoted my career to caring for my patients and working to make the health care system better,” Gawande said in his introductory memo. “I believe all people deserve quality health care that is both affordable and accessible.”
