Our humble beginnings

Like most CROs, Databean’s management team started in academia then moved to industry before coming together in 2007 to found Databean. We were driven by the lack of comprehensive and affordable clinical trial solutions for medtech and biotech start-ups. Our primary mission is to foster the rapid growth of these companies so they can bring their technologies to market as soon as possible.
