We believe evidence is a duty, not a chore
Our digital treatments Sleepio and Daylight aren’t just based on science: They’ve been proven effective in gold-standard clinical trials.
Setting the standard for rigorous clinical evidence
We believe digital treatments must be put to the test as rigorously as traditional medicine. People’s mental health depends on it. That belief not only fuels our commitment to clinical evidence — it also drives our efforts to make research more equitable for underserved populations.
