Daily Active Users (DAU) is a metric that measures the number of unique users who engage with a SaaS product on a daily basis.
It helps SaaS companies track user engagement, retention, and product stickiness.
Why Do Daily Active Users Matter for SaaS Companies?
DAU is important because it:
- Measures daily engagement and product adoption
- Indicates product stickiness and user loyalty
- Helps identify trends in user activity over time
- Supports feature improvement and retention strategies
- Assists in forecasting growth and revenue potential
High DAU typically correlates with higher retention and long-term customer value.
