FAQs
What is the difference between MAU and registered users?
Registered users (or total accounts) count everyone who has ever created an account — including dormant users who signed up years ago and never returned. MAU counts only users who took a qualifying action in the last 30 days, making it a meaningful measure of current engagement. MAU/Registered Users gives the engagement rate of the total user base. Reporting registered users as a proxy for active engagement is misleading.
How is MAU used in valuing consumer tech companies?
Consumer tech companies are often valued on Price/MAU or EV/MAU multiples, particularly before profitability. Historical acquisition multiples: Instagram was acquired at ~$33/MAU, WhatsApp at ~$42/MAU, LinkedIn at ~$60/MAU. These multiples reflect expected future ARPU generation and strategic value. MAU quality (engagement depth, demographic composition, geographic distribution) matters as much as raw count.
What causes MAU to spike without being a meaningful signal?
MAU spikes from viral marketing campaigns, press coverage, or app store featuring events may not reflect sustainable engagement — users are attracted by novelty but don't form habits. These 'hollow MAU' cohorts have high early churn. Analyze MAU cohort retention (what % of new users from a given month are still active in month 3?) to distinguish genuine engagement growth from marketing-driven inflations.
