Once product-market fit is achieved, the singular obsession must be retention. Before focusing on expansion metrics like NRR or efficient acquisition (CAC), you must first prove you can stop the "leaky bucket" and keep the customers you've already won.

The 'MQL death cycle' is over. Forward-thinking marketing organizations should align around Net Annual Recurring Revenue (Net ARR) as their ultimate measure of success. This metric, which combines new customer acquisition with retention, forces a focus on the entire customer lifecycle and proves marketing's contribution to sustainable business growth.

It's a common mistake to focus solely on the excitement of signing up new members. However, without tracking retention, you could be losing more members than you gain. A healthy program requires focusing on both acquisition and retention KPIs to avoid going backward.

A CMO was fired despite creating a $50M pipeline because it targeted the wrong customers who wouldn't renew or expand. Marketers can secure their roles and prove business impact by demonstrating how their efforts contribute to NRR, the company's true health metric.

Everyone obsesses over Net Revenue Retention (NRR), but Gross Revenue Retention (GRR) is the real indicator of product health. GRR tells you if customers like your product enough to stay, period. A low GRR signals a core problem that expansion revenue in NRR might be masking.

Don't obsess over preventing every customer from leaving (logo retention). Instead, focus on increasing the spend of remaining customers (revenue retention). Even with customer churn, you can achieve overall growth if your loyal customers expand their usage and spend more over time.

Organizations invest heavily in planning for new logo acquisition (territories, ratios, pipeline) while the post-sales motion is often an afterthought. This is a critical misallocation, as existing customers generate over 70% of revenue and 100% of profits, since new customer acquisition has associated costs.

The key indicator of a healthy SaaS business is Gross Dollar Retention (GDR), which measures retained revenue from a customer cohort before upsells. Companies with 95%+ GDR can grow efficiently, while those below 90% become 'living dead' as they constantly spend to replace churned customers.

Jon Miller highlights a fatal flaw in the common practice of calculating marketing budget by working backward from new ARR goals. This "reverse waterfall" model is entirely focused on net-new acquisition, which means it inherently allocates zero budget for marketing to existing customers, crippling retention and expansion efforts.
