Funder fit

NIHR i4i / Innovate UK Biomedical Catalyst / SBRI Healthcare

7.1m UK adults with tinnitus. No NHS treatment pathway. Browser-based digital therapeutic with research-grade pitch matching.

Problem

7m+ UK adults have tinnitus. No NHS digital pathway.

Most receive a leaflet and discharge. Existing apps are paywalled, app-store gatekept, or single-technique. People who can't afford private audiology are left with nothing between diagnosis and self-management.
