Matomo consultant: real expertise, not just another Analytics Agency

Looking for a Matomo consultant who actually knows the product inside out? At Openmost, Matomo is not a line on a long list of tools we support. It is our entire focus and has been since 2017.

Why Hire a Matomo Consultant?

Matomo is a powerful platform, but its depth of features can become a blocker without the right guidance. A Matomo consultant turns the tool into a real decision-making asset for your organization.

Common situations where our clients reach out:

  • You just installed Matomo and data is not tracking correctly
  • Your instance is slow or misconfigured for your traffic volume
  • You need to prove GDPR/CNIL compliance and are unsure about your settings
  • You want to implement a full tracking plan using Matomo Tag Manager
  • You are migrating from Google Analytics and need end-to-end support

Why Openmost?

Certified Matomo Partner. Openmost is one of the few agencies certified by Matomo worldwide. We are not generalist analytics consultants — Matomo is all we do.

Matomo plugin creators. We develop and maintain extensions on the official Matomo marketplace: Tag Manager Extended, Weather Reports, ChatGPT for Matomo, Mistral AI, BigQuery Importer, and more. We know the platform at the code level.

A network of top Matomo specialists. We work alongside recognized experts in the Matomo ecosystem (Ronan Chardonneau, Frédéric Forster, Jean-Marc Courtiade) to cover every angle: technical, marketing, and training.

Active in the Matomo community since 2017. We contribute open-source plugins, produce reference documentation in French, and help shape the Matomo ecosystem through tools and content.

Trusted by leading organizations. Government agencies, NGOs, large retailers, and SMBs trust us with their analytics — from the Cour des comptes to Handicap International, from Le Slip Français to Cojean.
