+| Adoption measured as:
MAU/Purchased seats (%) | Used as a measure of monthly adoption within a customer’s total licensed user base.
This applies to most deals that do not have an unlimited deal contract (unlimited licensed seats). |
+| Adoption measured as:
MAU/TAM (%) | When a customer is on an unlimited deal contract (unlimited licensed seats), the account team will use TAM (Total Addressable Market) as a denominator.
TAM is the total amount of possible end-users that can use the Sourcegraph platform at a given company. |
