Atlanta-based agency ARPR announced that it has named Raj Choudhury CEO.

Choudhury succeeds agency founder Anna Ruth Williams in the chief executive role. Williams will now serve as ARPR's chief strategy officer.

Choudhury's appointment comes after taking an ownership stake in the firm. Financial terms of that transaction were not made public.

Choudhury has co-founded four agencies prior to his arrival at ARPR. His first shop, the digital agency Spunlogic, was founded in 1998. His venture Engauge was later acquired by Publicis Groupe. He also previously served as CEO for social ad tech company BLiNQ Media.

"Modern technology brands need integrated marketing agencies that are both creatively obsessed and technically sophisticated," Choudhury told O'Dwyer's. "I'm excited to join forces with the ARPR leadership team as we accelerate our mission to build an agency model that doesn't exist in the marketplace today—but will be required for tech brands to stay competitive tomorrow."

ARPR, which opened in 2012, focuses on tech PR. It counts Instant Financial, Intelerad, PaySend, RxBenefits, SonicWall and Updox as clients. The agency accounted for nearly $3.9 million in net fees last year, according to O'Dwyer's rankings of PR firms.
