The answers we need are all around us. Litmus is a clinical data science platform focused on health-related quality of life.

We use real life data collected at the point of experience from wearables, smart devices, and home sensors to guide management and to inform both new and traditional endpoints. We help our customers describe the full value of their work in observational studies, therapeutical trials, and post-market research. From small observational studies to large scale registries, we help researchers unlock fundamentally new insights from remote and telemetric patient data.
