Quantcast is a global leader in finding and identifying audiences on the open internet. As it built to a significant rebrand and a relaunch of the Quantcast Advertising Platform, Antidote was briefed to manage Quantcast’s agency communications across Europe, alongside our retained UK work. Coordinating with the Quantcast marketing team and the US agency, Antidote managed three other tech PR agencies to ensure that the strategy and messaging were consistent globally.

Antidote led on agency comms and reporting for teams across Europe, including Italy, Germany and Sweden. While each team also liaised and reported individually through its local country team, Antidote ensured that all communications were on message, and delivered the best possible results at a crucial time for the business.

Antidote advised each agency on communications strategy, provided content support and coordinated spokespeople and reporting with the internal Quantcast team. This streamlined the process and standardised the messages across the continent. The collaboration included marshalling stories in major national business titles, including Dagensmedia and Forbes.

The Quantcast Advertising Platform was relaunched successfully, with universally positive reviews from key industry publications, including Horizont and Engage.
The agency teams secured 106 pieces of coverage in target publications across Europe in H1 2024, causing Quantcast’s share of voice to grow against key competitors.
