Less than two years ago, AOL made the biggest acquisition of CEO Tim Armstrong’s tenure, paying $405 million for ad tech startup Adap.tv.
Now much of Adap.tv’s senior management has left. The most recent departure is co-founder Amir Ashkenazi, who was CEO of Adap.tv up until its sale to AOL in September 2013, and then became president of AOL’s “Platforms” technology group. Ashkenazi left earlier this month.
“Amir’s contributions to AOL will live on well past his departure and we wish him well,” an AOL rep said in a statement.
Adap.tv’s software helps people buy and sell video advertising via an exchange. AOL’s purchase represented a large bet in two crucial areas for Armstrong: “Programmatic” — that is, automated — ad buying, and video.
AOL hasn’t announced a replacement for Ashkenazi, but a person familiar with the company said his responsibilities will essentially be divvied up between Don Kennedy, who heads up the sales side of AOL’s advertising business, and Amit Kapur, who runs the company’s publisher business. Both men report to Bob Lord, who oversees all of AOL’s ad and tech operations.
Ashkenazi is one of several Adap.tv executives who have left in the last year, including Ashkenazi’s co-founder Teg Grenager, who had been the company’s chief product officer and left late in 2014. Former president Toby Gabriner left last spring.
As Kara Swisher has reported AOL is in the midst of a significant sales re-org. People familiar with Ashkenazi’s departure say it’s not directly connected to that restructuring. But former Adap.tv employees say some of the startup’s workers have had a hard time figuring out how to work with AOL’s existing employees and infrastructure.
