Amazon has acquired Health Navigator, a startup that develops APIs for online health services. According to CNBC, which first reported the deal, Health Navigator will become part of Amazon Care, its pilot healthcare service program for employees.

This is the second health startup acquired by Amazon. The first was online pharmacy PillPack, purchased by the company in 2018 for slightly less than $1 billion. PillPack’s services have also been integrated into Amazon Care, which offers deliveries of prescriptions with remotely communicated treatment plans.

Health Navigator’s platform was created to be integrated into online health services, including telemedicine and medical call centers, to standardize the process of working with patients. Its platform includes natural language processing-based tools for documenting health complaints and care recommendations, and is integrated into apps with APIs.

The startup, founded in 2014 by physician David Thompson, has not made a public statement about the acquisition yet, but CNBC reports that the company is telling customers their contracts will not be renewed.
