A good primary metric should quantify the value you're delivering to your customers, indicating how much they want your product, with revenue being the best metric.

Your primary metric must capture whether your product provides recurring or enduring value to users, such as monthly recurring revenue for SaaS tools.

Your primary metric should also be usable as a feedback mechanism, helping you prioritize strategies and make quick decisions in your startup.

For B2B companies, revenue should be the primary metric tracked, as it directly reflects the company's success.

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.

In biotech or hard tech businesses, your primary metric might not be revenue or active users, especially if you're still validating whether your technology works. Instead, focus on technical milestones that demonstrate progress.

Track a key performance indicator (KPI) that reflects your company's success; for most, this should be revenue or user engagement.

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.

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