Ariel Cohen argues that the strongest competitive advantage is a product that employees love. He backs this with a powerful statistic: in Navan's history, only six enterprise customers have ever churned, and five of them later came back, highlighting retention driven by superior user experience rather than contracts.

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.
A sale is just the first step. The true measure of product-market fit is high retention, specifically when the product becomes so integrated into a customer's workflow that the idea of canceling their subscription would be bizarre and disruptive. Founders should be designing for this "weird to cancel" status.
Users will switch from an incumbent if a competitor makes the experience feel effortless. The key is to shift the user's feeling from maneuvering a complex 'tractor' to seamlessly riding a 'bicycle,' creating a level of delight that overcomes the high costs of switching.
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.
Investing in "product delight" isn't a soft initiative; it has hard ROI. Studies show that emotionally connected users are twice as likely to stay with a product and twice as likely to buy more services. They are also 60% more likely to provide referrals, creating a powerful business case.
The current AI hype cycle can create misleading top-of-funnel metrics. The only companies that will survive are those demonstrating strong, above-benchmark user and revenue retention. It has become the ultimate litmus test for whether a product provides real, lasting value beyond the initial curiosity.
Analysis shows that approximately 70% of customer churn is not caused by issues with product, service, or pricing. The primary driver is emotional: customers leave because they feel neglected and unimportant. Retention strategies should therefore focus on making clients feel understood and valued, which is often a low-cost, high-impact activity.
The ultimate proof of product-market fit isn't just low churn; it's a "smile curve" on a cohort retention chart. This occurs when users who previously canceled later return to the product. This "just kidding, I'm back" behavior is a powerful signal that the product is indispensable.
Successful onboarding isn't measured by feature adoption or usage metrics. It's about helping the customer accomplish the specific project they bought your product for. The goal is to get them to the point where they've solved their problem and would feel it's 'weird to churn,' solidifying retention.
Don't just sell a product; become an indispensable part of your customer's workflow. By offering integrated products and services, you create a value ecosystem that locks out competitors and makes leaving an impractical and undesirable option.
