Marley Health Aims to Bring Clinical Rigor to Pet Wearables
London-based startup Marley Health launched Tuesday with a mission to bridge the gap between consumer pet gadgets and medical-grade diagnostics. By leveraging machine learning from Oxford University and clinical data from the Royal Veterinary College, the company plans to turn everyday activity tracking into validated, actionable veterinary insights.

The pet technology sector has seen a surge in devices tracking location and activity, yet many products lack the scientific validation required for medical decision-making. Marley Health intends to disrupt this landscape by applying the same clinical standards used in human healthcare to veterinary medicine. The company’s platform relies on a specialized smart collar designed to monitor physiological biomarkers, including gait, posture, resting heart rate, and respiratory rate.
Unlike standard trackers, Marley’s intelligence layer focuses on longitudinal health changes rather than isolated data points. Dr. Amanda Boag, co-founder and chief medical officer, emphasized that the goal is to provide veterinarians with clinically relevant information rather than raw, uninterpreted data. The company is currently preparing to pilot its technology with veterinary organizations across the UK. These deployments are intended to refine clinical workflows and further validate the platform’s biomarker accuracy against real-world veterinary benchmarks. With leadership drawn from Johnson & Johnson and Oxford’s Computational Health Informatics Lab, the firm is positioning itself as a scientific authority in an increasingly crowded, lightly regulated market.
