Why Fast-Growing SaaS Companies Keep Losing Customers They Should Have Kept

by Sandrine Moreau, Fractional Chief Customer Officer, International Executive Consulting

As a SaaS grows rapidly, it can be difficult for founders and leaders to appreciate that there will come a day when growth slows down. In the moment, all is well, new logos are being added, new employees are coming on board, and new features are being released to customers. The pace can be frenetic and all-consuming, distracting from what will become a pressing concern down the line.

We tend to neglect our departing customers slightly in favor of those arriving.

We all get excited when our company is growing like a rocket. Everyone wants to ride that fast-moving wave of customers, revenue and growth. It's only when growth slows down or someone builds a cohort analysis to show the decay of revenues over the last 18 months that we get to see the real numbers. And the reason most of those "lost" customers didn't need to be lost in the first place. Not because the competition won out or budgets were cut. But because there were gaps in your customer infrastructure that prevented you from growing sustainably in the first place.

When a fast-growing SaaS company starts to lose customers they thought were locked in forever, there's always a root cause at play. Identifying that cause is the first step to recovery.

"Customer retention is not a support function. It is your most powerful growth lever."

Sandrine Moreau, Fractional Chief Customer Officer

Your CS Team Was Hired Too Late and Set Up to Fail

When you're just starting out, you'll often find that there's been a very incorrect, albeit typical, balance spent on sales and marketing versus customer success. The company can't afford to spend as much money on customer success as they have spent growing the customer base. The result: the customer base grows at a very different rate than the company's ability to service it.

Your first CS hires have been hired too late and too junior for the task at hand. They've been set up to handle too many accounts with not enough in the way of specialized tools or automation. They have loosely or no defined metrics for success and are essentially running in reactive mode until release or renewal, trying to triage support escalations as they come in, rather than keeping the whole customer base healthy.

Customers who had issues with the product ultimately churned because nobody found out about the problems before they left. No gradual decline in usage that would trigger a "Hey, is everything okay?" from Support or Account Management. Only during renewal conversations, many months later, do you find out why customers said no. It's always amicable and always logical.

I think it's smart to invest in CS before you feel growing pains. It's hard to treat customer retention as a growth lever as opposed to a support function but that's what leaders do.

Ask yourself:

· Do we know when a customer is struggling before they tell us?
· Are our CS hires resourced to be proactive, or just reactive?
· Is customer retention treated as a growth priority or a cost center?

Your ICP Drifted and Nobody Adjusted

In high-growth environments, pressure to close a sale intensifies. The definition of a "good" prospect expands as targets loom closer. Edge cases advance through the funnel. Customers are within the ICP but not the ideal customer.

Churn often occurs at 6 to 12 months. But upon further review, those customers weren't a good fit. They were using the product for something completely different than its intended use case, or their company size and complexity was misaligned with what the CS team could actually support.

Customer Success should have a voice much earlier in the process. CS data the signals from customers who renew without issue and refer others, and the signals from customers who churn at month 8 after multiple escalations should be shaping who sales targets in the first place. By using CS data when forming sales strategy, you bring in customers you know how to serve well. That cleans up the pipeline, leads to higher conversion rates, and most importantly leads to higher retention rates.

Ask yourself:

· Is our CS team contributing to ICP definition?
· Do we know which customer profiles churn, and are we still selling to them?
· Are we letting growth pressure push us to close the wrong deals?

The Customer's Success Was Never Defined

Churn caused by misinterpretation of your data is probably the most common and most silent cause of preventable churn. At every touchpoint with customers, from the initial sale through onboarding and the quarterly review, success was never explicitly defined from their perspective.

It's easy to get distracted by measuring vendor-side metrics like adoption, support tickets, NPS, and health score. But the customer has invested 12 months and significant budget to solve a business problem for themselves. When they look back, they will be judging success against their own metrics, not yours. High adoption does not necessarily mean the customer will renew. It means they haven't decided to churn yet.

The customer definition of success is everything. Initiating that conversation early in the relationship and reaffirming it early in the renewal conversation is critical. What was the customer's problem? What does success mean to them in measurable terms? You want to walk away from every renewal conversation with a clear understanding of what makes the renewal an easy yes for the customer.

Ask yourself:

· Have we defined what success looks like for each customer in their language?
· Are we measuring what matters to us, or what matters to them?
· Do our renewal conversations start with their outcomes, or our metrics?

Operational Excellence: The Secret Nobody Is Talking About

The world of SaaS is crowded. Many companies compete in the same space with similar pricing and often the same feature set. One of the easiest things to replicate at scale is providing a good customer experience: high-quality support, timely communication, and optimized internal processes. While you can't guarantee these things remain constant as you grow, your goal should be to prioritize customer retention above everything else.

The experiences that matter are not singular moments. They are an ongoing impression that your company is capable and serious about customer success. That impression translates directly into renewal, customers choosing to renew without any additional selling effort.

In too many organizations, poor customer experience goes unacknowledged. Users don't always complain. They continue to pay, with no outward awareness of the negative impression building in the back of their minds. When a competitor comes knocking, or budget season forces hard decisions, the case for renewing will not be as strong as it should have been and you will wonder why.

Ask yourself:

· Are our CS processes designed to create a lasting impression of excellence?
· Do we know how customers actually experience working with us, not just what they say in NPS?
· Would our customers describe us as capable and serious about their success?

Customers. You Get to Keep Them Forever. They Become Your Business.

Most people are familiar with two versions of a SaaS business model. In the first, you must add customers at an aggressive pace just to hit your numbers, only to have 20% to 40% of those customers churn out the other end in a few months or years. In the second, you acquire customers and continually grow their accounts, earning their loyalty and turning them into advocates who generate warm pipeline for your company.

The distance between customer success and customer advocacy is the distance between a purposefully designed customer success strategy and an accidentally growing CS team. Many fast-growing SaaS companies are losing customers they could easily keep. That's because customer retention is not yet as important as customer acquisition to the company's growth strategy. But when retention becomes as important as acquisition, the company can experience a powerful and sustainable transformation and it all starts with a single decision.
