We are driven by our mission to advance the development of new treatments.

Medidata’s journey started in 1999 when a scientist working on his first clinical trial waded through inefficiencies and delays, and knew that technology could improve the process. Over time, we’ve grown to be the leader in clinical technology, with thousands of people working towards the same goal: using the latest technology to help our life science clients bring their life-saving new treatments to the public.
