The company's founders, John Naybour and Paul Atherton, aim to enhance patient outcomes by informing better clinical decisions. Mercia Ventures' Rob Hornby emphasized the potential for cost reduction in patient dissatisfaction treatments. Lizzy Upton from the British Business Bank highlighted the regional economic benefits fostered by the NPIF II's support.
