Little Journey was founded by Dr Chris Evans, a paediatric anaesthetist and researcher who witnessed first-hand the impact that procedural anxiety, poor preparation, and inconsistent communication can have on patient experience, engagement, and clinical outcomes. Partnering with Sophie Copley, an expert in human-centred product design, the healthcare platform was developed and demonstrated significant benefits in improving care efficiency, compliance and patient experience. It was rapidly adopted across the NHS supporting children undergoing surgery, before being expanded to support a wide variety of common procedures. Building on this initial success, Little Journey expanded into clinical trials, applying the same principles of personalised education, emotional support, and engagement to research settings. Our Life Science platform, Trial Flow, supports trial participants and their families across therapeutic areas, to alleviate the burdens they face as they navigate participating in a clinical trial. The platform is now a global solution, and we work with major pharmaceutical companies.
