Who We Are: Themison is danish health tech startup driven by a passionate team of innovators reimagining clinical trials for a new era. We’re building AI agents and leveraging behavioral science to revolutionize how trials are managed, making them faster, smarter, and truly patient-centered. Our mission is simple: create tools that empower trial managers, support patients, and make the clinical trial experience better for everyone. The Problem: Clinical trials are meant to help people, but today, the patient experience is often overlooked. Clinical trials today are overwhelmed by outdated processes: manual workflows, disconnected systems, and limited patient insights. Trial managers and staff juggle endless tasks, leaving little capacity to meaningfully engage and support patients. This inefficiency leads to delays, high dropout rates, and escalating costs, preventing life-saving treatments from reaching those who need them most. Why This Matters: The pharmaceutical industry is at a pivotal moment. As the search for blockbuster drugs becomes harder and patents on key treatments expire in the coming years, the race to bring new therapies to market is more competitive than ever. Pharmaceutical companies, contract research organizations, and clinical sites must work faster and more efficiently to stay ahead. In this new era of Agentic AI, Themison equips trial managers and staff with the tools to lead. Our AI-powered platform streamlines workflows, predicts and addresses patient engagement challenges, and reduces dropouts. By ensuring patients receive the support they need, trials run faster, smarter, and more effectively. Together, we can accelerate the delivery of life-saving treatments, making healthcare more accessible, affordable, and patient-centered. Join us in shaping the future of clinical trials.
