Chiswick’s role is understood to have a wider remit than that of Ahern, who left Digicom at the end of September.
He will be responsible for developing new inventory and additional revenue streams, and for working with Digicom’s current and prospective partners.
Chiswick, former head of agency sales at CBS Outdoor, has worked at Digicom on a consultancy basis since June, identifying ad partners for Amscreen’s BP Connect network.
Goddard, Digicom’s executive chairman, said he was certain Chiswick’s broad expertise would be extremely valuable.
At Dunnhumby, Chiswick was most recently commercial director for Tesco.com.
