Volta builds and operates a nationwide network of free-to-use electric vehicle (EV) charging stations. The charging stations are front and center at prime retail venues, featuring six-foot-high, backlit advertising surfaces. EV drivers enjoy free charging, supported by sponsorship and advertising revenue. Volta's head-turning charging stations are in high demand by advertisers and sponsors, making for a quick payback and high ROI. The company is backed by eBay founder Pierre Omidyar's sustainability fund.
