Beaverton shoe giant Nike today announced the 10 start-up companies taking part in its Portland-based Nike+ Accelerator program. 

In a format similar to many other business accelerators, Nike provides $20,000 seed funding to each of these companies, as well as use of office facilities in Northwest Portland and access to business mentorship and potential investors (including Nike). Each of the 10 companies will be creating products designed to link up to the Nike+ fitness-tracking technology platform.

TechStars, a Boulder, Colo., based business accelerator, will be running the program, and will receive 6 percent equity in each of the companies. See WW's interview with TechStars CEO David Cohen, which touches on Nike, the Portland tech scene, and the possibility of another tech bubble-and-bust.

The released list of participating companies, which includes several makers of game-and-reward-based products, is below:
FitDeck: Digital decks of exercise playing cards that deliver ever-changing workouts for fitness and sports. GoRecess: Helps users find, book and review fitness activities. Chroma Games: An indie game studio that creates virtual worlds tied to real-world activity.
