Schedule participant sessions. Across your entire team.
Run user studies, academic interviews, or clinical sessions without drowning in scheduling logistics.
How research teams use Merge
UX research programs with 30+ participants who each need a 60-minute session with one of several researchers.
Academic studies where faculty and graduate researchers share a participant pool and need fair distribution of sessions.
Clinical research with strict scheduling windows and participant-specific researcher assignments.
Multi-site studies where researchers and participants are in different timezones and sessions must happen during reasonable local hours.
Keeping participant data private — no one sees anyone else's schedule. The algorithm handles the matching so researchers and participants never share calendars.
