IMPACT assesses a range of data inputs such as TV programmes, sports matches and social media to trigger digital ad campaigns in response to relevant events, allowing companies to run their ads during the moments of “greatest consumer interest”.
IMPACT has already been deployed within a number of GroupM agencies but a deal has now been inked with the wider group.
"GroupM's mission is to bring competitive advantage to its clients and companies, a mission that is aligned with the performance that IMPACT delivers," said a delighted Nelius De Groot - Mporium's chief executive.
"This agreement provides Mporium with access to GroupM's agencies, who serve many of the largest global brands and advertisers.
"We look forward to further developing our relationships with the GroupM agencies, to deliver the best results for their clients."
Last month, Mporium penned the agreement with one of the world’s “largest and most prestigious" performance marketing agencies, which operates in more than 50 countries around the world and is part of one of the largest communications agencies around.
