Castor

Castor is a top-rated eClinical data management platform that provides a comprehensive suite of solutions — including EDC, ePRO, eCOA, eConsent, IWRS, CDMS, and decentralized clinical trial (DCT) tools — all on a single, unified platform. Founded in 2012 by Dr. Derk Arts, Castor has grown into a trusted global partner for some of the largest CROs, biopharma companies, medical device innovators, and academic research institutions worldwide. The platform supports over 17,000 studies across 90+ countries, serving more than 223,000 users and 8 million patients, with a 98% customer satisfaction rate and 95% on-time delivery record.

Castor's mission is to solve the world's healthcare challenges with research data, with a vision of creating a future where all data contributes directly to discovering cures for the world's diseases. The platform addresses critical industry pain points: approximately 80% of clinical trials are delayed due to patient recruitment challenges, 85% fail to retain enough participants, and over 70% rely on manual data transcription between systems. Castor is purpose-built to eliminate these barriers and accelerate research timelines.
