Amazon acquired Health Navigator

Amazon.com Inc. has acquired Health Navigator, a medical technology startup, in an effort to bolster its health care offerings for employees.

The start-up will be wrapped into a clinic for workers that launched last month at the company’s Seattle-based headquarters. Called Amazon Care, the program offers virtual and in-person consultations, and delivery of prescriptions to employees’ offices and homes.

The company’s ambitions in health care have been the subject of fevered speculation in the industry and among investors well versed in Amazon’s record of disrupting established industries. Amazon has partnered with Berkshire Hathaway Inc. and JPMorgan Chase & Co. to launch Haven, a non-profit working on ways to halt the rise in employee health-care costs.

Separately, the company is working to build on nascent businesses that sell to health-care providers and consumers. Amazon last year bought PillPack, an online pharmacy. It also sells office and medical supplies through its Amazon Business program.
