Product Owner

Who is Castor?

“Castor’s customer-centric products have supported medical researchers to capture over 1.2 million data points! As one of our Product Owners, at the heart of our product organization, you’ll ensure we deliver the best software solutions for the clinical trial space, contributing on our journey to improve medical research with technology.”  - Derk Arts, MD Ph.D., CEO @ Castor.

Who is Castor?

Castor is a leading cloud-based clinical data platform working with some of the world’s largest medical device companies, biopharma, and renowned academic institutes.

We simplify the clinical trial process, from recruitment to analysis, with user-friendly, patient-centric technology. Our mission is to bring medical research into the digital age. Why? Because medical research is still largely run using free-text, paper, and legacy technology.

Our self-service platform enables our users to run remote, device enabled, patient-centric trials. By helping our users capture high-quality data and making it machine-readable, we are fundamentally changing the flawed evidence-based medicine process.

How is Castor supporting the Coronavirus crisis?

Castor has joined the global fight against the Coronavirus by making our research data capture system available for free for all COVID-19 research projects. Castor is supporting more than 250 COVID-19 studies across the world, including the World Health Organization’s SOLIDARITY trial.
