The Team

Leon studied biochemistry at ETH Zurich, is trained in AI and financial modeling from IBM and Wharton, and leads the company's technical direction: system architecture, model and safety design, and accountability for reproducibility and regulatory compliance in the engineering. He founded Vivarus Diagnostics on the conviction that the rare disease diagnostic gap is now a data and reasoning problem rather than a scientific one — the knowledge required to recognise most of these conditions already exists in published criteria, and the evidence usually already exists in the patient's record.

Carsten has held chief executive and president-level positions at pharmaceutical companies specialising in rare disease therapies, with responsibility for European commercial operations, market access and product launches. He leads commercial strategy, partnerships with therapy developers, financial planning and reimbursement.

His view of the problem comes from the other end of it: he has launched treatments for conditions whose patients were still, on average, years away from being identified. Vivarus Diagnostics exists because that gap does not close by itself.

Dev is a qualified medical doctor whose career has been spent in legal and strategic roles in the pharmaceutical industry. He owns clinical strategy, clinical evaluation authorship, regulatory and data protection compliance, and the risk-benefit case for the system — the combination of medical training and regulatory practice that a Class IIa submission requires in one person.
