Castor is a health-technology company that builds a cloud-based eClinical platform for running clinical trials - from electronic data capture (EDC) and eConsent to eCOA/ePRO and real-world evidence. Founded in 2012 in Amsterdam by physician-researcher Dr. Derk Arts, Castor set out to replace clunky, expensive trial software with a self-service, researcher-friendly system. Today it supports more than 15,000 studies across 90+ countries and is used by leading CROs and biopharma companies, while pushing decentralized trials and practical AI (Castor Catalyst, built with Google Cloud) into mainstream research.
Derk Arts is a Dutch physician-turned-entrepreneur and the founder and CEO of Castor, a clinical-trial software company he started in 2012 after coding the first version of its Electronic Data Capture platform himself. Trained as a medical doctor and epidemiologist with a PhD, he built Castor to make clinical research more inclusive, patient-centric, and data-driven. The platform now supports thousands of trials across roughly 90 countries and was used by the World Health Organization for its Solidarity Trial. Castor has raised more than $60 million, including a $45 million Series B in 2021, and Arts is a recognized voice on decentralized trials, eConsent, and the responsible use of AI in research.
ClinCapture is an eClinical software company that builds cloud-based tools for running clinical trials - electronic data capture (EDC), ePRO/eCOA, eConsent, randomization, medical coding, and trial master file management. Born from consulting firm Clinovo and once known as the only free, fully validated open-source EDC in the world, it now markets a unified, AI-augmented platform called Captivate that lets sponsors and CROs design, launch, and manage studies from a single validated cloud system.
Curebase is a San Francisco-based eClinical software company building an AI-powered platform that runs clinical trials around patients' lives instead of inside hospital walls. Its single system spans study startup to database lock - combining electronic data capture (EDC), eConsent, ePRO/eCOA, patient recruitment, and a virtual research site model - so sponsors can launch decentralized and hybrid trials faster, capture cleaner data, and reach more diverse participant populations.
Medable is a Palo Alto-based digital health company building a cloud SaaS platform for decentralized and hybrid clinical trials. Its tools - eCOA+, Total Consent, Sensors, and Televisit - let pharma sponsors and CROs run studies remotely, enrolling patients in over 60 countries and 120+ languages.
Medrio is a San Francisco-based eClinical software company that helps pharma, biotech, medtech and diagnostics teams run clinical trials with a no-code, cloud-based EDC, eCOA/ePRO, eConsent and RTSM suite. Founded in 2005 and bootstrapped for more than a decade before taking outside capital, Medrio now powers thousands of studies across four continents.
Tom Lemberg is the Founder & CEO of Curebase, a San Francisco-based decentralized clinical trial platform that has enrolled over 60,000 patients across 60+ studies. A Harvard-trained computer scientist and molecular biologist, Lemberg built Curebase from his couch in 2017, joined Y Combinator in 2018, and raised $59M to transform how clinical trials work - letting patients participate from home and bringing their own doctors into the research process. Named to Forbes 30 Under 30 in 2022, he's on a mission to make clinical trials accessible to any patient, anywhere.
