Valencell, a Raleigh company that makes earbud sensors that allow a person to monitor their health while listening to music, said today that it has raised $5.5 million in venture capital funding.
The investment round was led by Best Buy Capital, the investment arm of retailer Best Buy, and also included TDF and True Ventures.
Valencell said it will use the money to expand its team, increase licensing agreements and expand the capabilities of its products.
The company currently has six employees.
When integrated into a headset, Valencell's Healthset platform enables earbuds to track a person's heart rate, number of calories burned, distance traveled and other measurements.
The data can then be streamed to smart phones or other devices.
Valencell earlier raised $1 million venture funding.
