Gubbins' responsibilities include developing publisher relationships with a focus on growing mobile and video inventory, as well as increasing spend with agency trading desks, programmatic buying units and demand side platforms (DSPs).
His previous ad-tech experience includes positions at Adbrain, Weve, the Rubicon Project and StrikeAd. Gubbins will report to Bill Swanson, vice president of EMEA at PubMatic.
Swanson said Gubbins is "a proven performer who brings with him a wealth of experience."
In February, Real-Time Daily reported that PubMatic’s global chief revenue officer Rob Jonas left the company for the role of SVP-revenue at analytics firm Factual. PubMatic also recently announced that it's a partner for China-based Tencent OMG’s (Online Media Group) ad inventory outside of mainland China. In December, the company laid off more than 100 employees and announced plans to focus on larger customers.
