Efficient Frontier

Efficient Frontier was a digital advertising optimization and search marketing company founded in 2002 that applied algorithmic, finance-inspired bid optimization to manage over $1 billion in annual marketing spend across search, display, and social (notably Facebook ad buying) for enterprise clients such as Discover, Travelodge, and Match.com. Adobe acquired the company in late 2011 (announced November 30, 2011; completed January 2012) and folded its multi-channel ad forecasting, execution, and optimization capabilities into the Adobe Digital Marketing / Advertising Cloud. The efrontier.com domain now redirects to adobe.com and the company has no independent website, developer portal, or public API.

Efficient Frontier is profiled on the APIs.io network. Tagged areas include Company, Advertising, Digital Advertising, Search Marketing, and Social Advertising.
