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.

Many businesses reach a million in revenue through sheer effort but then stall. The shift to scaling requires achieving product-market fit, which creates leverage and pulls in customers, leading to exponential profitability instead of diminishing returns from just pushing harder.

Many founders mistakenly define Product-Market Fit by revenue (e.g., "$1M ARR"). The correct measure is the ability to predictably create customer value. This is best quantified by a leading indicator for long-term retention, not sales figures, as revenue can be achieved without true market fit.

The true indicator of Product-Market Fit isn't how fast you can sign up new users, but how effectively you can retain them. High growth with high churn is a false signal that leads to a plateau, not compounding growth.

Many founders mistakenly believe achieving product-market fit is the final step to explosive growth. However, growth only ignites after also finding a repeatable go-to-market fit, which translates the founder's initial sales success into a scalable process that a sales team can execute consistently.

Founders often mistake $1M ARR for product-market fit. The real milestone is proven repeatability: a predictable way to find and win a specific customer profile who reliably renews and expands. This signal of a scalable business model typically emerges closer to the $5M-$10M ARR mark.

Many marketing failures aren't the marketer's fault, but a result of joining a company that lacks true product-market fit. Marketers excel at scaling demand for something with proven value, not creating demand for a vague idea. It's crucial to verify PMF before accepting a role.

Founders mistakenly define product-market fit by revenue or customer numbers. A better definition is achieving a high retention rate, proving customers get long-term value. This prevents scaling a business that can't retain its customers.

When facing uncertainty across your entire GTM strategy, prioritize the foundational elements. Begin with the customer experience: decreasing time-to-value and increasing expansion (NRR). If you cannot retain and grow existing customers, acquiring new ones is a futile effort that only masks a deeper problem.
