Our mission
Our mission is to get research teams from data to evidence with less manual work, so treatments reach patients sooner.
Clinical research still runs on too much manual data handling and too many disconnected systems. Castor exists to close that gap: one platform for data capture, and AI-assisted extraction, with a human reviewer in the loop, for the source data that used to be reviewed by hand.
~80%
of clinical trials are delayed due to patient recruitment challenges.
85%
of clinical trials fail to retain enough participants.
> 70%
of trials rely on manual data transcription between systems.
12%
of drugs that enter clinical trials get approved.
x2
Clinical trial data volume is doubling every 2 years, yet 80% remains siloed.
12%
Increase in clinical trial cycle times in the past 5 years.
Our vision
We want a future where research data moves quickly and cleanly into the evidence that brings better treatments to patients.
Research teams have run more than 19,000 studies on Castor to date, in 170+ countries, and Castor Catalyst brings AI-assisted extraction, with human review, to the source data behind them. Getting there means four things. We turn siloed data into connected, reusable evidence. We design for participants, with bring-your-own-device (BYOD), eConsent, and quality-of-life measures. We remove barriers with self-service and API-first tools. And we apply AI where it earns its place, with a human reviewer approving the output.
Our history
Our history
Castor started in 2012 as a project by Dr. Derk Arts, a physician-researcher who saw how much clinical research time went to moving and cleaning data by hand. What began as an electronic data capture tool is now a clinical trial data platform used by medical device, biopharma, diagnostics, and academic teams, with Castor Catalyst adding AI-assisted clinical data extraction, built on Google Cloud AI, with human review.
Castor has particular strength in post-market and real-world evidence for medical device manufacturers, including more than 800 medical device studies to date. A human reviewer approves the AI output before it enters the record.
