Key Performance Indicators (KPIs) are quantitative metrics that indicate how healthy your business is, helping you understand its current state at all times.

Having a main key performance indicator (KPI) is essential for tracking a startup's progress and determining whether the business is working or not.

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.

Writing down my priorities and tracking my key performance indicators (KPIs) is essential to identify bottlenecks and understand why revenue may not be growing as fast as it should.

Real startup progress is defined by tasks that genuinely move the needle, such as growing your primary key performance indicator (KPI), which is typically either revenue or active users.

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.

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.

Track the right metrics, focusing on returning usage, NPS, and paying customer renewal rates to gauge product market fit.

Maintain a spreadsheet of ideas that could potentially move your primary KPI, focusing on two main activities: talking to users and building your product. These tasks are essential for converting users into customers and understanding your product's roadmap.
