Chart Refresh Retainer
Monthly updates to an agreed cohort retention visualisation so your review pack stays current without restarting the brief each time.
From £780 / month · Ongoing, monthly cycle · Remote
Who it is for
Teams that already completed a Cohort Retention Map and need the same visual language updated each month as new cohorts mature.
Included each month
- Ingest of your agreed extract
- Updated retention matrix and annotations
- Change log noting which cohorts shifted
- Optional 30-minute clarification call
Constraints
Retainers require a fixed cohort definition and file format. Material changes to tracking or segment logic pause the month until we re-scope. Minimum commitment is three months; notice terms appear in the engagement letter.
