  • Who we are

    Who we are

    LumenAI features 10 years of research in Machine Learning and 20 years of experienced engineers in Database Optimization and Data Management. We master state-of-the-art technologies ranging from data science to Big Data and Cloud.


    LumenAI uniquely combines data science and data engineering to deliver high-end services, to bring you to the market and to become an unavoidable actor and game changer in your sector thanks to Machine Learning.

    We help companies...

    • Understand and overcome their machine learning issues. We address questions from "what to do with my data" to "how can I get value from my business and decisions" or "how can I upgrade my methods to highly performing ML technologies"

    • improve their products and services, treat IoT sensors, and add value with predictive maintenance

    • change business models from product-based to a pay-as-you-use service.

    We do research

    We are pioneers in real-time machine learning algorithms.

    This field is growing in demand with the rise of IoT, massive online data production applications, and needs for immediate decision taking and privacy.


    LumenAI is an innovative start-up emerging from a research project at the French University.

    We give life to our theorems in digital apps and adapt our results for industrial needs. We believe that making connections between academic researchers and industries can have positive impact on both sides. This is our daily motivation that we are building.

    We do not recommend storing and accumulating a large amount of data to analyze a batch mode. The future of data science is the ability to treat the real time. This is one of the most challenging next steps in Data Science. Endowed with our expertise in online learning, we want to be an actor of this revolution.

    Employee initiative and involvement, liberating leadership and corporate transformation are also very important ingredients of LumenAI. We share a world-class vision that combines the common good - great research and challenging performance - with the personal well being of employees - often called happiness!

    From the beginning, we are largely inspired by the lean startup movement and the build-measure-learn feedback loop. The first step is figuring out the problem that needs to be solved and then developing a minimum viable product (MVP) to begin the process of learning as quickly as possible.

  • Testimonials

    Julien Hervouet (CEO) & Florent Gosselin (R&D manager), iAdvize :

    « LumenAI a permis une intégration "from scratch" d'un algorithme d'analyse comportementale à forte valeur ajoutée. Les résultats observés sont très probants et nous ont permis d'ajouter une approche prédictive de nos clients. L'accompagnement de LumenAI s'est manifesté à plusieurs niveaux dans l'expertise, la formation, le design et le développement d'outils de DATA science (stockage, calcul, analyse et aide à la décision). Son interaction avec l'équipe DATA Science du pôle R& D a été une expérience très positive. »

    Anthony Barré, Lead Data Scientist, AccorHotels :

    « Nous avons collaboré avec LumenAI sur une preuve de concept algorithmique de grande complexité. L'expertise scientifique et la vision extérieure apportées par LumenAI ont permis tout au long du projet de structurer la problématique et d'étudier des pistes pertinentes de solutions. Les échanges nourris avec LumenAI ont en effet été moteurs dans les choix effectués, permettant également de débloquer des verrous scientifiques rencontrés. Cet accompagnement régulier constitue une partie intégrante au succès de ce projet. »
