About us

Learn about Castor, our mission, and the team.

A short history

During his MD training, our founder Derk Arts, identified a major problem in medical research. Due to the unavailability of affordable, easy to use data capture tools, researchers were deviating to non-compliant alternatives that reduce data quality, security, and reusability.

In 2012 Dr. Arts invented Castor which enables researchers to easily capture and integrate high-quality data from any source on one compliant platform. Thousands of medical device, biotech, and academic researchers around the world are now using Castor EDC (Electronic Data Capture), eCRF, ePRO, and eTMF to accelerate their studies.

Castor currently employs more than 50 people that are passionate about transforming medical research across its headquarters in Amsterdam and an office in the United States.

AI powered clinical trials

Our goal

Our goal is to make the world’s research data reusable, enabling AI-driven clinical trials, and ultimately creating a future in which we maximize the impact of data through reuse.

We are currently collaborating with 30,000 researchers, academic institutions and commercial companies across 90 countries. Our platform has supported more than 4,000 studies that cover a broad range of disease areas including diabetes, cardiovascular disease, rare diseases, and cancer. Researchers on the platform generate vast amounts of data from traditional and decentralized trials, and we recently reached milestones of 110,000,000 data points and 1,300,000 enrolled patients.
