Virginie Chesnais, CMO of Happydemics, on why advertising measured by the entities that sell it is a structural conflict of interest, how full-funnel brand lift measurement creates genuine accountability, and why advertising is only valuable if it generates real impact among the audiences it reaches.
"Advertisers spend billions. They must be able to rely on measurement that is reliable and not biassed."
Why independent measurement is not optional and why full-funnel brand metrics are what the industry actually needs
Virginie Chesnais has been CMO of Happydemics for seven years, helping build the company from a niche brand lift measurement tool into a global advertising effectiveness platform. The mission has stayed constant: provide the industry with independent measurement it can trust.
In this conversation Chesnais makes the case that the structural conflict of interest in advertising measurement, where the entities that sell advertising also measure its effectiveness, is one of the most important unresolved problems in the industry. Happydemics provides full-funnel brand metrics from consideration through to purchase intent, across all media and formats.
"Happydemics is a global solution for measuring and optimising advertising effectiveness across all media. We provide full funnel brand metrics: consideration, brand familiarity, purchase intent, preference. We collect these among the targeted audiences of the campaign."
Chesnais frames Happydemics not just as a measurement company but as a trust infrastructure provider. The value is the independence of the data.
"Advertisers have to rely on data that is reliable and not biassed. We know that advertising is often measured by actors that sell it. And this can no longer be. So that is where we step in."
Chesnais is direct about the conflict of interest. When a media owner provides its own measurement, there is an incentive to produce results that justify the spend.
"Our methodology has not evolved. That consistency is actually what allows clients to compare effectiveness across different channels in a standardised way. What has changed is our ability to apply it across more environments."
The constancy of the methodology is a feature: it allows genuine cross-channel comparisons.
"Collaboration cannot thrive without trust. We are positioned as a trusted third party for assets, agencies, and publishers. We sit at the intersection of all these players. Collaboration is crucial in this increasingly fragmented industry."
Independence makes serving all sides of the advertising transaction simultaneously possible.
"Our product was built around a powerful belief that advertising is only valuable if it generates a real impact amongst audiences. If it resonates. That is the standard we hold everything against."
Chesnais returns to first principles. All the technical sophistication exists in service of one question: did this actually change anything for the people it was supposed to reach?
"Advertising is only valuable if it generates a real impact amongst audiences. If it resonates."
