Under Armour is quickly and quietly becoming the worldwide leader in digital fitness. In March, the company opened up a technology division in Austin, and since then they have acquired four companies, the latest being Gritness.
Gritness is an app that offers users a search engine to find local group workouts based upon what they are looking for. Additionally, Gritness allows users to more easily organize group workouts in their nearby area. The company is based in Austin and is the second Austin-based corporation acquired by Under Armour.
