01

Upload your attendee list

Drop a CSV or Excel file with your attendees. AfterCircle reads name, email, and an optional topic column to help balance groups.

02

Cohorts are generated instantly

Groups of 4–6 are formed automatically, each assigned a unique color from a palette of 10. No manual sorting, no spreadsheets.

03

Attendees get a personal email

At your scheduled send time, each attendee receives an email with a link to their personal color card — no app download, no account needed.

04

Hold up your phone to connect

Attendees open the link and a full-screen color fills their phone. They hold it up and instantly find everyone in their cohort.
