As the CEO of WhatsApp, what are the top 5 metrics you should focus on to measure the app's success?

As CEO of WhatsApp, I would prioritize these five key metrics:

1. Daily Active Users (DAU) & Monthly Active Users (MAU): These are fundamental to understanding user base size and engagement. A high DAU/MAU ratio signifies strong user retention and habitual usage.
2. Message Volume (Sent/Received): This metric directly reflects the core utility and activity on the platform. Consistent growth indicates users are actively communicating.
3. User Retention Rate: Measuring the percentage of users who return over specific periods (e.g., 7-day, 30-day) is vital for long-term health and growth.
4. Feature Adoption Rate: Tracking the usage of new or key features (e.g., Status, Video Calls, Business API) shows how effectively we are evolving the product and meeting user needs.
5. Monetization Metrics (where applicable): Depending on the business model (e.g., WhatsApp Business API, potential future services), metrics like revenue per user, conversion rates for business interactions, or transaction volume would be critical.
