Our independent, human-scale organization offers tailored services in electronic data capture (EDC), data management, statistics, and methodology. We support all phases of clinical studies, from protocol design to data analysis and publication, with a constant focus on quality and transparency.
Our team brings together experienced and complementary profiles, working with a wide range of partners: biotechs, medtechs, pharmaceutical companies, and academic institutions.
Since 2014, we have been accredited under the French Research Tax Credit (Crédit Impôt Recherche) and are actively involved in several innovative projects.
Our work, regularly published in scientific journals and presented at conferences, demonstrates a strong commitment to R&D.
eXYSTAT continues to evolve by adopting new tools, strengthening strategic partnerships, and actively preparing for the challenges of tomorrow: artificial intelligence, real-world data, and connected medical devices.
A conscious model
Unlike large CROs, eXYSTAT has chosen a controlled-growth model to ensure responsiveness, strong commitment, and highly personalized services. This approach is also reflected internally through a company culture built on mutual trust, employee autonomy, and virtually no staff turnover.
Our forward-thinking HR policy promotes long-term engagement and well-being at work — as evidenced by the loyalty of our teams and the implementation of a four-day workweek since 2023. Our model is grounded in five core values: honesty, quality, transparency, simplicity, and friendliness.

“We have had the pleasure of working with eXYSTAT since Cureety’s inception; we entrusted the company with the clinical evaluation plan for our remote monitoring medical device software. Five clinical studies have already been completed, and the results of these studies have enabled us to obtain reimbursement for our medical device from the French national health insurance system. eXYSTAT’s expertise in methodology and biometrics has been instrumental in robustly evaluating the performance and organisational and clinical benefits of our digital medical device; we highly recommend eXYSTAT!”
