It's important to track a few secondary metrics alongside your primary metric to gain a comprehensive view of your startup's health, rather than focusing solely on one metric.

Avoid vanity metrics and focus on clear, actionable metrics that can guide your startup's strategy and decision-making processes.

When choosing KPIs, focus on one primary metric that you would bet the whole company on, as it simplifies your focus and helps you determine how well your startup is doing.

It's crucial to be honest about your startup's current status and to regularly fill out your primary metric and goals to maintain accountability and track progress effectively.

Once you're building your product, defining your primary metric helps align your team on who your target users are and how to attract them.

Analytics, including primary and secondary metrics, are crucial for driving the MVP and product-market fit process, helping you test and focus your team after achieving product-market fit.

Your goal should be to grow your primary metric consistently, as this indicates you're creating something that people want and that can scale effectively.

The primary metric should be a lagging indicator of success, reflecting real value delivered, like revenue from customers who have already paid for your product.

KPIs act as a feedback mechanism for your current strategies, such as user acquisition and feature launches, allowing you to prioritize your time and course correct as needed.
