About
Mehdi Oudjida is an independent digital-analytics consultant in France who runs WISSI and the With Data Studio ecosystem. He is best known as the creator of Companion, one of the most-used third-party Chrome extensions for Data Studio, and for a body of tutorials, hacks and custom visualisations that push the tool beyond its defaults.
Companion fills the gaps in Data Studio’s interface — bulk-editing fields, batch-updating names and descriptions from a Google Sheet, wider formula fields, and content obfuscation for safe sharing — the everyday friction report-builders hit constantly. Alongside it he publishes original custom visualisations (a funnel chart, a GA4 heatmap, a podium chart for tracking AI-chat referral traffic) and premium report templates.
With around nine years of intensive Data Studio practice and a longer analytics career, he has worked with brands including Michelin, Groupe Casino, Euromaster and SQLI, and since 2023 consults part-time with Analytics Ninja. He teaches through his blog, the With Data Studio YouTube channel and a newsletter.
