Empowering patients, hospitals, and researchers with privacy-first AI solutions that accelerate clinical trials and unlock personalized care, securely and equitably. OASYS NOW is on a mission to make personalized healthcare accessible to everyone, everywhere, starting with the safe, smart use of data. Founded by a refugee technologist and a genomic privacy researcher, we build cutting-edge AI and cybersecurity tools that empower hospitals, researchers, and patients alike. Our story begins with a personal one: a mother without access to her own medical records and a scientist blocked from data she needed to fight Alzheimer’s. Those moments inspired us to reimagine the infrastructure of health. We knew the problem wasn’t lack of data, it was that the right people couldn’t use it, safely and efficiently. So we built OASYS NOW: a secure platform where data flows with purpose, and control stays where it belongs, with the people it represents. Our AI-powered tools help clinical trial sites and hospitals identify eligible patients from messy real-world data — including handwritten notes, referral letters, and unstructured EHRs. No manual query building. No black boxes. Just explainable results delivered in minutes, not months. We’ve won awards for cybersecurity and privacy innovation, and were named winners of the Slush 100, Europe’s most competitive startup competition. But what makes us most proud is the trust we’ve earned: from clinicians, data privacy officers, patient organizations, and global partners like NVIDIA and Google. Whether it’s accelerating trial recruitment, enabling GDPR-compliant data sharing, or giving patients control through our GRIP app, OASYS NOW is building a future where healthcare is faster, fairer, and deeply human.
