A Key Performance Indicator (KPI) is a metric used to measure the success of a startup's business strategy. KPIs are specific, quantifiable goals to track progress toward a startup's objectives.

They provide insights into the performance of various aspects of the business and help to identify areas for improvement.

For startups, KPIs can measure a wide range of outcomes, such as user engagement, customer acquisition, revenue growth, user retention, and product usage.

By tracking the performance of these metrics over time, startups can get a better understanding of how they are progressing toward their goals and make informed decisions about how to improve their business. For example, a startup might set a KPI to increase its Monthly Active Users by 10% each quarter or to reduce customer churn by 15% in the next 6 months.

By tracking these KPIs, the startup can monitor its progress and adjust its strategy as needed to achieve its goals.
