How would you 💭 start tracking KPIs in a startup with no tracking systems, only a CRM?

As I am brainstorming on which are the most efficient ways to help a startup get organized by implementing data tracking systems and monitor KPIs. The transition is the most challenging part since there are different tools to consider... Some KPIs worth monitoring: 💪Churn Rate: Monitor the rate at which customers cancel subscriptions or cease purchasing. 💪Sales Pipeline Velocity: Measure the speed at which leads move through the sales process. 💪Customer Satisfaction Score (CSAT): Gauge customer satisfaction with the product and service. 💪Product Adoption Rate: Assess how quickly customers are embracing new features or offerings. 💪Average Revenue Per User (ARPU): Determine the average revenue generated per customer. 💪Customer Retention Rate: Track the percentage of customers retained over a specific period. 💪Customer Engagement Metrics: Monitor user interactions with the SaaS platform, such as login frequency, feature usage, etc. What have you done that has helped you?
