MAU
Abbreviation · Startup & VC
Definitions
Monthly active users, the count of users who meet a defined activity threshold in a 30-day period. MAU is useful for measuring breadth of active usage, though it can hide weak depth if defined poorly.
In plain English: The number of users who actively use the product in a month.
Example: "MAU kept growing, but weekly frequency inside that user base was flattening."
