Depending on your startup's stage, industry, and focus, you may use different KPIs to measure your development. For instance, to measure growth you may look at monthly recurring revenue (MRR), customer acquisition cost (CAC), customer lifetime value (LTV), churn rate, net promoter score (NPS), and viral coefficient. Additionally, you can track revenue with gross profit, net profit, cash flow, burn rate, runway, and break-even point. To measure customer satisfaction you may use customer satisfaction score (CSAT), customer effort score (CES), customer retention rate, and customer loyalty index. Additionally, product quality can be measured with product-market fit, feature usage, user feedback, bug rate, and uptime. Finally, innovation can be tracked with research and development (R&D) spending, number of patents, number of new products or features, and time to market.
