Salary benchmarks
Our take
The last decade has seen huge growth in digital advertising revenues. For the first time in 2019, digital ad spending surpassed traditional ad spending in the U.S.
To market effectively, brands need a clear understanding of their customers. Epsilion provides connections between people and brands for marketers through its PeopleCloud platform, unifying otherwise disconnected marketing data into profiles of 250 million unique consumers. Once this data is assembled and anonymized, each profile is assigned a "COREID", a secure and verified profile that stays with the consumer. This allows Epsilon's customers to ensure that they are always reaching the right people with their marketing efforts, and that they are complying with increasingly strict privacy and data protection regulations.
Epsilon counts many well-known brands among its clients, including L'Oréal, Marriott, John Lewis & Curry's. In 2019, Epsilon was acquired by Publicis Groupe for $4.4 billion, one of the largest acquisitions in marketing history. The recent acquisition of Yieldify by Publicis and its future integration with Epsilon will greatly improve Epsilon's personalization capabilities and strengthen the company's offering to mid-market clients.
