Why Speaking to Lost Customers May Be Your Best Growth Strategy
By Phil Faust, Founder at Faust Forward
When a customer walks away, whether by canceling a subscription, failing to renew, or choosing a competitor, it can feel like a closed door. Most companies quickly log the churn, perhaps tagging a reason code in their CRM, and then move on.
But here is the truth: lost customers are one of the richest, most underutilized sources of insight your business has.
At Faust Forward, we often advise product leaders and executives to look beyond the comfort of existing users and lean into the difficult, often uncomfortable conversations with those who decided not to stay. Conducted well, these conversations can refine your product, positioning, and even your culture.
Why Talk to Lost Customers?
They Tell You the Unvarnished Truth
Current customers often temper their feedback because they want to preserve goodwill or avoid conflict. Lost customers do not have that filter. They will tell you exactly where you fell short, what frustrated them, and why they left. This is pure gold to your product team and often sales and support processes as well.
That raw honesty can be tough to hear, but it is invaluable. It cuts through assumptions and reveals where the real gaps lie.
You Uncover the Real Reasons for Churn
Internal dashboards and exit surveys rarely capture the nuance of churn. Was it truly about price, or was it that the value did not match the cost? Did they leave because of a missing feature, or because onboarding felt overwhelming?
By talking to lost customers, you go beyond surface-level explanations to uncover root causes. These insights can shape both product and strategy.
You Learn About Your Competitors From the People Who Switched
When a customer leaves for a competitor, they have frequently run a live A/B test between your offering and another. Talking to them gives you a direct line to what the competitor is doing better, or at least differently enough to win. Moving away from the status quo is the most challenging solution in any sales process. If a customer has made this choice, they have very good reasons that you need to understand if you hope to address them effectively.
This intelligence can help you understand market dynamics, identify where you are vulnerable, and refine your differentiation.
You Create Opportunities for Win-Backs
Not every lost customer is gone forever. Sometimes the timing was not right, the product was not ready, or their needs shifted temporarily. Reaching out to understand their perspective shows humility and care, and it can lay the groundwork for future re-engagement.
Even if they do not return, they will often appreciate being asked, which keeps the door open. Hearing you’re a product manager responsible for the product and you just want to learn what can be done to make it a better solution for them frequently opens the door to future opportunities.
You Sharpen Your Positioning and Messaging
Lost customers often highlight mismatches between what you promised and what they expected. Maybe your messaging targeted the wrong audience. Maybe your sales team emphasized a feature you could not deliver.
This kind of feedback helps you refine who you are really for and ensure your product story attracts the customers most likely to succeed with you.
You Build a Learning Culture
Making lost customer interviews part of your operating rhythm sends a powerful cultural signal: we do not just celebrate wins, we learn from losses.
That humility and curiosity can strengthen cross-functional alignment and foster a healthier, more resilient organization.
How to Do It Well
If you are ready to start, here are a few tips:
Reach out personally. A thoughtful, respectful note (or even a phone call!) is more effective than an automated survey.
Be quick and efficient, and let them know. Allow a couple of weeks after the loss before your follow-up, but don't wait longer than 30 days, or details you hope to uncover may be lost. Request only 30 minutes for the interview.
Make it about learning, not selling. Do not push to win them back; listen first.
Ask open-ended questions. Questions like “What drove your decision?” or “What could we have done differently?” spark deeper insights.
Synthesize and act. Share themes with your team and build them into product, marketing, and service decisions.
The Strategic Advantage
Speaking to lost customers is not about dwelling on failure. It is about mining a goldmine of insight that most companies leave untapped.
The best product leaders do not shy away from uncomfortable truths. They seek them out. Because they know the fastest way to improve is not to ask happy customers what is working, but to ask lost customers what is not.
At Faust Forward, we help product teams and executives unlock exactly these kinds of insights, turning churn into clarity and feedback into forward momentum.
