Mediarithmics: sovereignty score and 8 European alternatives

mediarithmics is a French customer data platform for data-driven enterprises in sectors such as retail, media, telecom, travel and finance. It combines known and anonymous audience data through deterministic identity resolution, so that marketing, data and ad operations teams can segment, analyse and activate audiences in real time across marketing and media partners. Its modules cover marketing personalisation, cookieless audience monetisation, data collaboration, attribution and e-merchandising. The platform can also run as a zero-copy CDP on the customer's existing data lake, avoiding data duplication.

mediarithmics is headquartered in Paris and, following a combination with Easyence, is active in Retail + Media. Its developer documentation states that it acts as a data processor under the GDPR, and the company says it is ISO 27001 accredited. A French company is subject to European law. The company does not publish its hosting provider or region on its website, so record them in the data processing agreement.

Why digital sovereignty matters with Mediarithmics

Mediarithmics is headquartered in FR and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Mediarithmics scores best on data residency.

Mediarithmics is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Mediarithmics together with your other vendors and gives a total score, a heatmap and the main risk drivers.
