About Markellia
The team and conviction behind proof through data.
Our purpose
Markellia establishes verifiable, legally admissible facts from data. Our constant mission: to reduce information asymmetry between two parties, where it is most costly to the one who decides or funds.
This standard now extends across several lines of work — audit and client-side advisory (AMO) for public authorities, Passport for the art market — built on one shared technological and human backbone.
The founder
Markellia was founded by Arnaud Lutellier, a CentraleSupélec engineer and data leader for over 25 years (Canal+, SNCF, Lacoste). Over more than ten years within the SNCF group, he led the data and customer platforms of the incumbent operator.
