Digital marketing agency Efficient Frontier buys an Australian firm

Online digital marketing agency Efficient Frontier today said it had bought Downstream Marketing, a similar firm based on Australia. U.S.-based Efficient Frontier did not say how much it paid for the company.

Efficient Frontier services include search, social media and display marketing. The acquisition will enable Efficient Frontier to grow internationally and add to its mobile and social media marketing services, the company says.

Downstream Marketing’s clients include American Express Co., Avis, Sun Corp., Vodafone, Westpac and Weight Watchers International Inc., which is No. 81 in the Internet Retailer Top 500 Guide. Downstream Marketing has worked with Efficient Frontier since 2006, licensing the U.S. firm’s marketing technology.

“For the past five years, Downstream Marketing has successfully deployed Efficient Frontier’s platform to manage digital marketing for our name-brand clients,” says Steve Knowles, CEO of Downstream Marketing. “We’re excited to officially join forces with them to expand our product offerings in our market as well as provide additional global reach to Efficient Frontier’s existing client base.”
