eXYSTAT is the fruit of constructive and passionate discussions between clinical research professionals.

These exchanges led us to create this company with the ambition of offering expertise in the field of biometrics and clinical development. We take this a step further, proposing features distinguishing us from other biometrics groups currently operating in France.

Our technical expertise is the result of our complementary experience in clinical trials and epidemiological studies. From our backgrounds covering both subsidiaries and headquarters of pharmaceutical companies, as well as in biotechnology companies, our paths have allowed us to develop partnerships with institutional research groups and international Health Authorities.

The complementarity of our skills and professional experience makes eXYSTAT a solid and innovative company, breaking away from the classic mould of providing only conventional biometry services. Our focus on listening to the needs of our customers is reflected in our commitment to develop creative solutions which are both adapted to the study and personalized to the client, while integrating issues related to the global context of clinical studies. Our expertise combined with the strengths of our proposal, positions us as partners and active co-players of your projects.
