About Closed Loop Medicine
Closed Loop Medicine operates as a TechBio company focused on developing combination prescription products that pair drug therapy with digital software. Founded in 2017 by Dr. Hakim Yadi OBE, Dr. Paul Goldsmith, Dr. David Cox, and Dr. Felicity Sartain, the Cambridge-based firm aims to advance personalized medicine. The company's core business revolves around a proprietary platform that creates regulated, single-prescription products designed to optimize medication dosage in real-time. This is achieved by integrating data from medical devices, wearables, and patient-led digital experiences to create closed-loop models of care that adjust treatment for individuals.
The founding team brings together deep expertise in science, medicine, and technology. Dr. Hakim Yadi, the founding CEO, has a PhD in Immunology and extensive experience in the life sciences investment sector and government health policy. Co-founder Dr. Paul Goldsmith is a consultant neurologist with a PhD in developmental biology and a history of founding several healthcare businesses, including DanioLabs. This blend of clinical and commercial experience underpins the company's strategy. Since its inception, Closed Loop Medicine has raised over £22 million (c. $30 million) from investors such as Ananda Impact Ventures, BGF, and IQ Capital, enabling the development of its product pipeline.
The company's business model targets pharmaceutical companies, payers, and healthcare providers by creating patent-protected combination products that can enhance established medicines. By developing a software layer that accompanies a drug, Closed Loop Medicine aims to improve treatment efficacy, reduce side effects, and increase patient adherence, thereby lowering overall healthcare costs. The platform's initial focus areas include chronic conditions like hypertension and insomnia, with a broader pipeline of over 30 potential combination products. A recent partnership with Pharmanovia, for example, focuses on combining an anti-hypertensive drug with Closed Loop's Software-as-a-Medical-Device (SaMD) to offer personalized dosing. This approach allows the company to create new value for existing, trusted medications by turning them into precision medicine solutions.
