Palo Alto, California-based Human API raised $6.6 million from 16 investors, according to an SEC filing. Existing investors include Andreessen Horowitz, BlueRun Ventures, and Innovation Endeavors, according to AngelList.

Human API offers providers an infrastructure they can use to create a health platform that enables a group of patients to share data with their caregivers.

A few months ago, Human API CEO Andrei Pop told Information Week in an interview that the company aims to make it simple for a physician, nurse, researcher, or even a caretaker to retrieve this data.

The company allows providers to create a platform (either online or via mobile devices) that syncs different health apps and devices through a single authentication point. Human API also takes care of backend data management so its customers can aggregate data from a single API.

After customers sign up to build an aggregation platform, Human API provides them with pre-written SDKs and libraries as well as sample apps to copy and use.

Some Human API integration partners include Jawbone, Basis, Fitbit, Pebble, Withings, iHealth, RunKeeper, MapMyFitness, and Moves. If a company wants to integrate with an app or device that isn't listed, Human API will add them to the platform.

Pop also said that the company wants to integrate data from anywhere, which means they also plan to integrate traditional clinical data, lab data, and genetic data.

In 2013, Human API graduated from AngelPad, an accelerator founded by ex-Googler Thomas Korte.
