Detailed Review
mediarithmics is a Paris-registered customer data platform (3 rue d'Edimbourg, 75008 Paris) built specifically around a world without third-party cookies, rather than a cookie-era product with a cookieless mode added later. The pitch is real-time marketing personalization plus audience monetization: unifying first-party customer data, building segments from it, and activating those segments across channels and, distinctively, monetizing audience data directly rather than only using it internally.
The company recently merged with Easyence, a personalization and on-site search vendor, which extends the product further into on-site experience rather than leaving it purely as a back-end data layer. Like most of the European vendors in this category, mediarithmics does not publish pricing anywhere on its site — every deployment is scoped through a sales conversation, and no free trial is advertised.
For a European publisher or consumer brand that is actively planning around the end of third-party cookies rather than treating it as a future problem, mediarithmics' cookieless-first design is a genuine differentiator against CDPs that added consent and identity features onto an older architecture. The trade-off is the same one that runs through most of this category: no published price, and a smaller, less internationally recognised brand than the US incumbents.
What mediarithmics does well
- Built cookieless-first rather than retrofitted, relevant as third-party cookies continue to disappear
- Combines customer data unification with audience monetization, not just internal activation
- Recent merger with Easyence extends the product into on-site personalization and search
- Genuinely EU-based (Paris) with EU (France) jurisdiction
Where mediarithmics falls short
- No published pricing anywhere — every deal starts with a sales call
- No free trial advertised, unlike Piwik PRO in this same category
- Smaller, less internationally recognised brand than Twilio Segment or Tealium
- The Easyence merger makes near-term product roadmap harder to pin down from the outside
Standout feature. A cookieless-first design: audience monetization and personalization built around first-party identity from the start, rather than a cookie-based CDP with consent and identity resolution bolted on afterwards.
