Eulerian

Founded in 2002 by Guillaume Fougnies and Mathieu Jondet, Eulerian Technologies is an independent company which develops solutions for real-time analysis, automation and optimization of e-marketing operations. With proprietary technical architecture, the firm manages the entire production from building our servers to the user-interface.

Since its foundation, the company has been continuously investing, in R&D, in order to propose to its clients ever more efficient solutions that are adapted to their needs and to the ever changing e-commerce market. Driven by this dynamic, it is able to integrate every two month a new feature in its solutions.

Eulerian Technologies puts data collection at the service of e-commerce websites performance.

The solutions developed by Eulerian Technologies are based on an ultra-precise and secured method of information collection related to the online ads, to the website and to the users of e-merchant websites.

This information allows the e-merchants to monitor the performance of their marketing actions and to instantaneously optimize them in order to increase their ROI.

Thanks to its innovative solutions and its enduring collaboration with major e-commerce websites, Eulerian Technologies has become an important French player in real-time analysis and optimization of e-marketing operations.

The integration between Axeptio and Eulerian Marketing Platform enables brands to reconcile privacy compliance with data-driven marketing performance in a consent-centric and cookieless environment. By automatically transmitting consent signals collected by Axeptio’s CMP into Eulerian, this integration embeds user privacy choices directly into analytics and measurement workflows.

A major benefit is that consent data becomes fully exploitable within marketing analytics. Instead of being isolated from performance metrics, consent signals (acceptance, partial consent, or refusal) are analyzed alongside page views, conversions, and funnel steps. This provides teams with a clearer understanding of which portion of their audience is actually observable and how privacy choices impact reported performance.

By correlating consent data with engagement and conversion indicators, marketers can identify friction points caused by consent banners and optimize their user experience accordingly. Pages or campaigns with higher opt-in rates can be prioritized, while low-performing consent interactions can be improved through better messaging or design. Consent data therefore becomes a lever for optimization rather than a simple compliance requirement.

The integration also improves data reliability and interpretation. In a regulated environment, fluctuations in traffic or conversions can be misleading without knowing the consent context. Eulerian makes it possible to distinguish real performance issues from visibility loss due to consent refusal, enabling more accurate analysis and decision-making.

Currently, the integration captures CMP display events and user consent choices, which are accessible in Eulerian’s tracking parameters and can already be analyzed alongside business KPIs. Future developments include a dedicated consent dashboard, allowing teams to visualize consent rates, interaction rates, and opt-in trends directly within their marketing analytics environment.

Overall, the Axeptio–Eulerian integration transforms consent into a strategic data asset, aligning user trust, regulatory compliance, and marketing efficiency in a privacy-first digital ecosystem.
