The Pursuit of Sustainable Growth
“How do we get more customers?” “How do we drive more leads?” “How do we get…more?”
When companies equate growth with acquisition and have a “growth-at-all-costs” mindset, they tend to ask these types of questions.
But long-term growth isn’t about short-term wins.
It’s about building a foundation where customers stick around, grow with you, and ultimately become advocates for your brand.
Sustainable growth requires a balanced approach, with acquisition, retention, and churn mitigation working together as the three key components of a lasting growth strategy.
When businesses sprint for quick wins and fail to prioritize long-term goals, they’re setting themselves up for failure. Without retention or churn mitigation, growth isn’t just unsustainable; it’s impossible.
Acquisition obsession is an expensive vice. Acquiring a new customer is anywhere from 5 to 25 times more expensive than keeping one you already have. That means every dollar spent on acquisition has to work harder. The financial bleed is undeniable.
Customer Acquisition Cost (CAC) has skyrocketed—rising 222% in recent years—and businesses are losing an average of $29 for every new customer they acquire. And for all that effort? You have a 5-20% chance of selling to a new customer, compared to a 60-70% chance with someone who already knows and trusts you.
This obsession also creates a false sense of success. Bringing in new customers feels like progress, but if your churn rate is high, you’re not growing; you’re just replacing.
True growth isn’t about how many customers you can stuff into your pipeline. It’s about how many stick around, grow with you, and ultimately contribute to your bottom line. This type of growth can only happen when acquisition, retention, and churn mitigation are balanced and aligned.
The Problem with Acquisition Obsession
The True Price of Acquisition
Customer acquisition is an important piece of the puzzle, but it’s an expensive piece.
Every campaign, every cold email, and every sales demo are investments, and the return on those investments isn’t always as good as businesses hope.
For B2B companies, the average cost to acquire a single customer is $536. But then there’s also the cost of maintaining sales tools, running paid ad campaigns, designing onboarding experiences, and hiring teams to make it all happen.
Yet, despite rising costs, acquisition remains the default lever most businesses use when they consider growth.
Acquisition-only strategies give the illusion of growth, but if customers leave as quickly as they arrive, then the resources spent on acquisition aren’t building momentum; they’re just filling in gaps created by customer churn.
True growth isn’t about how many new customers you bring in; it’s about how many stick around and contribute long-term value.
While AI is often touted as the great equalizer in this space, with the potential to cut acquisition costs by 50%, it’s far from a plug-and-play solution. Implementing AI-driven acquisition strategies comes with its own challenges: expensive tools, steep learning curves, and the need for buy-in across teams.
The Hidden Costs of Obsession
Beyond the financial aspect, an acquisition obsession can also chip away at your organization in less obvious but equally damaging ways, including misalignment across marketing teams, an over-reliance on outbound channels, and missed opportunities for building lasting customer relationships:
- Employee burnout: Marketing, sales, and customer onboarding face mounting pressure to perform. This grind culture creates inefficiencies, mistakes, and, eventually, turnover.
- Missed opportunities: If you focus on filling the top of the funnel, you might be missing out on upselling, cross-selling, or referral opportunities with your existing customers.
- Short-term mindset: Quick wins are often prioritized over sustainable, long-term strategies.
The more resources you throw at acquisition without balancing it with retention and churn mitigation, the harder it becomes to build a truly scalable, profitable model.
Acquisition may be part of the equation, but it’s not the whole solution.
Customer Retention vs Customer Acquisition
- Fact: retention delivers significantly higher ROI than acquisition.
- Also fact: 44% of companies prioritize acquisition over retention, while only 18% prioritize customer retention.
Why would this possibly be?
Because acquisition is easier to track and brag about.
It’s all about vanity metrics like lead volume, click-through rates, or the number of new customers signed on. Retention, on the other hand, often requires deeper thinking: What’s the lifetime value of a customer? How do we keep them engaged and loyal?
Companies often default to acquisition because it’s tangible and immediate, especially when they prioritize growing their presence on social media or expanding into a new market segment rather than focusing on retaining and growing existing customers. It's easier to celebrate hitting lead generation goals than to quantify the long-term impact of retaining a loyal customer.
The result? Companies throw money at acquisition while ignoring the pot of gold that already exists in their customer base.
Finding the Right Balance
Both have their place. Achieving sustainable growth isn’t about choosing between them; it’s about balancing them.
For example:
- Early-stage companies should focus more on acquisition to build a strong customer base and ensure a great onboarding process to keep churn low.
- Attract the right people: Focus on your Ideal Customer Profile (ICP). Customers who align with your offering are more likely to stay.
- Mature companies with a stable customer base should allocate more resources toward retention strategies to drive repeat revenue and reduce churn.
When done right, retention lowers costs, fuels word of mouth, and makes acquisition more effective—turning satisfied customers into your strongest advocates.
A balanced approach ensures you’re not just adding new customers but creating a foundation for long-term, sustainable growth.
Retention: The Unsung Growth Hero
The Financial Impact of Retention
The companies that are able to survive long-term know retention is the real moneymaker, while the companies that burn out often obsess over acquisition while ignoring the fact that retained customers account for 65% of total revenue.
The customers who stick around don’t just keep spending—they spend more. They’re 31% more likely to increase their purchases and 50% more likely to try new products.
Retention is also a direct driver of Customer Lifetime Value (CLV), which is the total revenue a customer brings to your business throughout their relationship with you. It’s one of the most critical metrics in any business, yet only 42% of companies measure it accurately.
The best companies understand this and treat retention as a growth lever—ensuring that their customer service efforts are proactive, their products or services continuously provide value, and their marketing focuses on long-term engagement. Here’s how:
- Subscription models: Offering tiered plans or premium features keeps customers engaged and incentivizes loyalty.
- Freemium upsells: Start with a free offering to lower entry barriers, then upsell based on usage or added value.
- Personalized experiences: Customers are 80% more likely to make a purchase when brands offer personalized experiences.
Behavioral Patterns of Retained Customers
Retention also transforms the way customers engage with your brand. Retained customers aren’t just repeat buyers; they’re your advocates, testers, and walking billboards.
In some cases, they actually become your best employees:
- They recommend your brand to their network.
- They share reviews that win over skeptics.
- They defend your reputation when someone complains.
In other words, they become brand ambassadors.
Their loyalty saves you on CAC and fuels organic growth. But retention doesn’t just happen, it’s built on an exceptional customer experience, which 89% of companies say is critical to keeping customers. And oftentimes, you only get one shot at it, as 61% of customers leave after a single bad experience.
Bridging Retention Metrics with GTM Efficiency
Retention isn’t just for pumping up those revenue numbers. It’s also critical for GTM efficiency.
- Pipeline velocity: Companies that focus on retention are better at moving leads and customers through the sales process.
- Increased deal size: Happy customers are more likely to expand their investment in your offerings.
- Balanced growth: Retention fuels new user growth rate by ensuring that while you bring in new customers, you aren’t losing them as quickly as they arrive.
The Cost of Churn and Its Impact on Growth
When there’s high churn, it’s neatly impossible to have high growth.
While retention drives long-term growth and stronger profit margins, churn works in the opposite direction, eroding your hard-won progress.
It’s not just about losing one sale but rather everything that sale could’ve fueled in the future. The stakes are exceptionally high for subscription-based businesses or companies with long sales cycles, where every lost customer represents months, or even years, of lost revenue potential.

Operational Inefficiencies
The impact of churn goes far beyond the financial. It has a way of turning alignment into chaos. Just a few examples:
- Sales forecasting falls apart. When customers leave unexpectedly, your revenue predictions become unreliable, throwing off budgets, hiring plans, and growth strategies.
- Pipeline Unpredictability. Churn makes it harder to predict which deals will close and which customers will stick. This uncertainty wastes time and resources chasing the wrong priorities.
- Silo city. Churn results in a lot of finger-pointing. Sales blame marketing for attracting “bad leads.” Customer success blames sales for overpromising. Marketing posts a passive aggressive meme on LinkedIn about sales.
Why Does Churn Happen?
No company is immune from churn, but if you can understand its root causes then you can at least minimize it.
- Poor onboarding: If customers feel lost, frustrated, or unsupported in the early stages, they’re far more likely to churn.
- Lack of personalization: If your communication feels generic or irrelevant, customers will look for someone who “gets” them.
- Reactive support: Don’t wait for customers to come to you with problems. Proactive engagement, like health checks, can make all the difference.
Aligning GTM Teams for Sustainable Growth
When GTM teams are aligned, churn becomes less of a threat. Shared goals and unified data create a frictionless customer experience that drives retention and minimizes revenue leakage. Because churn tends to thrive in environments where teams are siloed, strategies are misaligned, and processes are inconsistent, there are ways to ensure your GTM teams are set up for success:
- Shared goals: Align all teams with KPIs that connect acquisition, retention, and churn prevention.
- Real-world processes: Use cross-functional dashboards and unified CRM tools to ensure everyone’s working from the same data and strategy.
- CRM platforms: Use tools like HubSpot to track the entire customer journey with full visibility and seamless handoffs. A shared platform allows teams to anticipate customer needs and act proactively.
- Lifecycle playbooks: Develop playbooks that guide teams through the entire customer lifecycle: onboarding, upselling, retention. This helps customers feel supported at every touchpoint.
The Future of Sustainable Growth
An acquisition-only mindset is unsustainable.
True growth isn’t about how many leads you cram into your pipeline. It’s about how many stick around, expand their investment, and advocate for your brand. Sustainable revenue growth is inevitable when acquisition, retention, and churn mitigation work together.
