We can finally put a name to the thing striking fear within the health care establishment: Haven.

The secretive new venture, created by corporate titans Amazon, Berkshire Hathaway and JPMorgan Chase to transform health care for their employees, has gone without an official name for more than a year.

It was nameless when a well known doctor was appointed last summer to run it. It was referred to only as ABC or ABJ in a recent lawsuit brought by giant health insurer UnitedHealth Group, which described whatever-it-was as a powerful potential competitor. (The venture would only say it had no current plans to compete, and a federal judge ruled against UnitedHealth.)

On Wednesday, the venture, which remains tight-lipped but insists its goal is not to make money, announced it was calling itself Haven and launched a website at havenhealthcare.com with a slogan, “It’s Time for Better.”

The name “reflects our goal to be a partner to individuals and families and help them get the care they need, while working with clinicians and others to make the overall system better for all,” according to the website.
