A short history

When he graduated in 2011, Derk Arts (MD, PhD, and epidemiologist) discovered that there was no  affordable, user-friendly application for data capture and management. With a background in IT, he developed the first version of Castor EDC, a user-friendly cloud solution for capturing medical research data in clinical trials.

Now, Castor has expanded into a team of 45+ people, specialized developers have taken over the development work, and we have become an established name within medical research.

Our goal

Our goal is to make medical research faster and smarter by enabling researchers with user-friendly technology.

A majority of medical research data is not reusable. This is due to poor data quality, lack of standardization, and numerous barriers making data inaccessible. We have developed Castor Electronic Data Capture (EDC) to enable researchers to capture high-quality, standardized data at the source and make it available for re-use. Castor is the most user-friendly and affordable EDC in the world and is being used by more than 28000+ users across 3500+ studies.

The team

Our team consists of Healthcare and IT enthusiasts who are eager to contribute to the advancement of medical research worldwide. We briefly introduce everyone on our team page.
