About Riya F.

I am a board-certified physician, entrepreneur, and computer scientist passionate about building technologies that accelerate healthcare innovation.As Co-Founder and COO of Cosign AI, I’m helping clinical trial sponsors and sites solve one of the biggest challenges in medicine: patient recruitment. Today, 85% of trials fall behind schedule, costing sponsors up to $8 million per day in lost revenue. At Cosign, we built AI agents that continuously evaluate patient information in real time—identifying the right candidates for the right trials. We’re already partnering with leading specialists and prestigious research groups in ophthalmology, processing patients weekly across 9 trial sites, and finding 2x more strong candidates per site. Our mission is simple: surface high-quality matches effortlessly, reduce workload, and close trials months ahead of schedule.Before Cosign, I practiced as a Physical Medicine and Rehabilitation physician, leading initiatives to improve patient care, communication, and outcomes across multiple hospital systems. Alongside my clinical practice, I co-founded healthcare services companies in billing and rehabilitation consulting, developing proprietary software solutions and scaling operations across institutions.My journey started with a B.A. in Computer Science from Rice University, which has given me a strong technical foundation to bridge medicine, technology, and entrepreneurship. From research in robotics and bioinformatics to building healthcare software and participating in NASA innovation challenges, I’ve always been driven to combine problem-solving and science to create meaningful impact.I thrive at the intersection of medicine, technology, and business—whether it’s treating patients, scaling startups, or developing AI to transform clinical research.
