CARMAnation
CARMAnation is a website for people to rent out their private parking. Founded by Ilya Movshovich and Ashley Cummings, in January 2013, and headquartered in San Francisco, the company is privately owned and operated by Carmanation, Inc.
Users of the site must register and create a personal online profile before using the site. Every parking spot is associated with a host whose profile includes recommendations by other users, reviews by previous guests, as well as a response rating and private messaging system.
The company is also looking into including corporate parking lots that clear out when employees go home after 5 pm.
