Matomo Launches Global Partner Programme to Deepen Local Connections and Champion Ethical Analytics
25 juin, par Matomo Core Team — Press ReleasesMatomo introduces a global Partner Programme designed to connect organisations with trusted local experts, advancing its commitment to privacy, data sovereignty, and localisation.
Wellington, New Zealand – 25 June 2025 — Matomo, the leading web analytics platform, is
proud to announce the launch of the Matomo Partner Programme. This new initiative marks a significant step in Matomo’s global growth strategy, bringing together a carefully selected
network of expert partners to support customers with localised, high–trust analytics services
rooted in shared values.
As privacy concerns rise and organisations seek alternatives to mainstream analytics solutions, the need for regional expertise has never been more vital. The Matomo Partner Programme ensures that customers around the world are supported not just by a world–class platform, but by trusted local professionals who understand their specific regulatory, cultural, and business needs.
“Matomo is evolving. As privacy regulations become more nuanced and the need for regional
understanding grows, we’ve made localisation a central pillar of our strategy. Our partners are
the key to helping customers navigate these complexities with confidence and care,” said
Adam Taylor, Chief Operating Officer at Matomo.Local Experts, Global Values
At the heart of the Matomo Partner Programme is a commitment to connect clients with local experts who live and breathe their markets. These partners are more than service
providers—they’re trusted advisors who bring deep insight into their region’s privacy
legislation, cultural norms, sector–specific requirements, and digital trends.
The programme empowers partners to act as extensions of Matomo’s core teams :
• As Customer Success allies, delivering personalised training, support, and technical
services in local languages and time zones.• As Sales ambassadors, raising awareness of ethical analytics in both public and privatesectors, where trust, compliance, and transparency are crucial.
This decentralised, values–aligned approach ensures that every Matomo customer benefits
from localised delivery with global consistency.A Programme Designed for Impactful Partnerships
The Matomo Partner Programme is open to organisations who share a commitment to ethical, open-source analytics and can demonstrate :
• Technical excellence in deploying, configuring, and supporting Matomo Analytics in diverse environments.
• Deep market understanding, allowing them to tell the Matomo story in ways that
resonate locally.
• Commercial strength to position Matomo across key industries, particularly in sectors with complex compliance and data sovereignty demands.Partners who meet these standards will be recognised as ‘Official Matomo Partners’— a symbol of excellence, credibility, and shared purpose. With this status, they gain access to :
• Brand alignment and trust : Strengthen credibility with clients by promoting their
connection to Matomo and its globally respected ethical stance.
• Go-to-market support : Access to qualified leads, joint marketing, and tools to scale their business in a privacy-first market.
• Strategic collaboration : Early insights into the product roadmap and direct
engagement with Matomo’s core team.
• Meaningful local impact : Help regional organisations reclaim control of their data and embrace ethical analytics with confidence.Ethical Analytics for Today’s World
Matomo was founded in 2007 with the belief that people should have full control over their data. As the first open–source web analytics platform of its kind, Matomo continues to challenge the dominance of opaque, centralised tools by offering a transparent and flexible alternative that puts users first.
In today’s landscape—marked by increased regulatory scrutiny, data protection concerns, and rapid advancements in AI—Matomo’s approach is more relevant than ever. Open–source technology provides the adaptability organisations need to respond to local expectations while reinforcing digital trust with users.Whether it’s a government department, healthcare provider, educational institution, or
commercial business—Matomo partners are on the ground, ready to help organisations
transition to analytics that are not only powerful but principled.
