AppNexus completes Open AdStream® acquisition and closes $110 Million funding round
New York – AppNexus, the world’s largest independent ad tech company, today announced the completion of its acquisition of Open AdStream® (OAS), a premium ad-serving technology. On September 22, 2014, the company announced that it would acquire OAS®, formerly known as Xaxis For Publishers, in a strategic transaction with WPP and Xaxis.
WPP also invested $25 million in AppNexus as part of a funding round led by a large, Boston-based public equity and asset management firm, totaling $110 million and which is now complete.
OAS® is one of the industry’s most trusted and effective platforms, having served prominent publishers around the world for more than 10 years. With the acquisition of OAS®, AppNexus has further cemented its position as a growing global technology leader dedicated to providing its clients with the most comprehensive solutions and powerful marketplaces in the industry. By combining AppNexus’ existing capabilities with the OAS® premium ad-serving technology, the company can offer a more complete technology stack to publishers that is independent from any media business and provides the latest innovations in a rapidly changing industry.
“We couldn’t have been more thrilled to welcome OAS to our world-class team at AppNexus, and to begin working together to build the most innovative publisher stack available,” said Brian O’Kelley, CEO and Co-founder, AppNexus. “From the very beginning, AppNexus has been revolutionizing the ad tech space, and we’ll continue to do so, providing all of our customers – including top programmatic media companies, agencies, advertisers, as well as publishers – with the best technology available to grow their businesses, and an independent platform that they can trust.”
One of New York’s most successful and highly-valued technology companies, AppNexus eclipsed $1 billion in total ad spend across its platform in 2013, and expects that figure to more than double in 2014, exceeding $2 billion. With the integration of OAS®, the company now has 800 employees across 20 global offices.
Specific terms of AppNexus’ acquisition of OAS® were not disclosed.
