Headquartered in New York, NY with sales offices in Chicago, Atlanta, Los Angeles, San Francisco and London, Spongecell transforms standard banner ads into dynamic flash ads with rich media-like functionality. The multi-media ads engage audiences longer, use no more real estate than a standard banner ad, and keep users on the publisher's page. Spongecell can seamlessly incorporate multiple actions in a single ad unit, providing consumers with the choice of how they want to interact with the ad. Spongecell works seamlessly with creative agencies, media agencies, ad networks, and ad exchanges. Spongecell's ads are lightweight, which run on any website on any placement in any size.
