Palo Alto-based PubMatic last week hired Bob Walczak as vice president. Walczak is an innovative mind in the mobile ad space, and will be working with PubMatic’s mobile and emerging media head Josh Wetzel.

“We are pleased to bring a strategic thinker like Bob Walczak to this team,” said PubMatic President Kirk McDonald in a statement. “Bob has demonstrated the kind of insight and vision that aligns with our promise to meet the current needs to our publisher parterns.”

Before joining PubMatic, Walczak was the Founder and CEO of Ringleader Digital. McDonald called Walczak’s Ringleader Digital a company that was “clearly ahead of its time [in 2005].”

PubMatic helps publishers sell their ad inventory. Wetzel said in the statement, “He will help publishers in their quest to differentiate and monetize their exploding volume of mobile inventory.”
