The number that taught me to build from the outside in
When I first joined ANZ Bank almost 20 years ago, I was handed a brief to grow the number of customers with active transaction accounts. The number that wasn't being discussed was that for every 100 accounts they were adding, 97 others were leaving or going inactive.
That number has stayed with me because I see the same pattern everywhere. Not always that extreme, but the instinct is there. Spend a bucket load at the top of the funnel and make salespeople the rock stars.
The companies that break this cycle make a fundamental decision to build the business around the person opening their wallet. That shift changes everything. Who you target. What you measure. Where you invest. And it starts by understanding that a satisfied customer is not the same thing as one who's actually staying. That's what it means to build from the outside in.
The North Star: why customer-driven wins
Every business follows a North Star - a dominant lens that shapes how it spends its next dollar and makes its toughest calls. Some are Product-Led: the 'build it, and they will come' philosophy that Apple made famous, betting that customers don't yet know what they want. Others are Sales-Led, built around conversion rates and the pursuit of quarterly targets. Some are Culture-Led, trusting that happy employees naturally create happy customers. Others are Mission-Led, chasing a cause.
These models can produce extraordinary results. Apple’s product-first philosophy - grounded in a deep understanding of how customers want technology to feel - is one of the most successful business strategies in history. But what most of them have in common is that the customer is the destination, not the foundation. They're the win at the end of the funnel rather than the starting point for every decision. And that often creates the pattern I described at ANZ. Enormous effort going in the front door. A quiet, steady bleed out the back. Or worse - a fundamental lack of product/market fit that stops customers from arriving in the first place.
For me, the model with a truly sustainable foundation is Customer-Driven - outside in, in strategic terms. Because the only reliable source of durable growth is the person opening their wallet. If they aren't winning, eventually, nobody is.
Going back to ANZ, when we looked at why customers were leaving, many were doing so at entirely predictable life moments. Buying a home, where the transaction account they'd held for years also worked as an offset mortgage. A customer-driven business would have known that. Would have been there at that moment with something relevant. Instead, we found out about it when they closed the account. The number wasn't a retention problem. It was a listening problem.
We've been measuring wrong: the evolution of customer thinking
The way businesses think about customer relationships has shifted over the past 30 years - and understanding that shift explains why so many outdated strategies fall short.
The satisfaction era (1990s–2000s): We asked, "Did we meet expectations?" CSAT became the default metric. Useful for spotting transactional issues like a call centre resolution, but it captured a moment, not a relationship. A customer could rate you 9/10 after a good interaction and still leave the next week.
The loyalty proxy era (2000s–2010s): Net Promoter Score asked "How likely are you to recommend us?" Its simplicity and benchmarkability made it powerful. But intent to recommend isn't the same as commitment. My family rotates through streaming services. We'd recommend most of them, and still cancel without hesitation when a new series of Ted Lasso lands and we need to switch Apple TV back on.
The experience & emotion era (2010s–2020s): Research from Gallup and Forrester showed that emotional connection predicts customer value far better than satisfaction alone. Businesses began mapping journeys and managing brand perceptions, not just transactions.
The behavioural era (Today): Today, engagement is understood as behaviour plus emotion over time. It shows up in product usage, support patterns, content engagement and renewal behaviour. The companies winning now don’t just measure how customers feel - they track what they do, and intervene before drift becomes churn. Crucially, they're also clear on the type of customers they actually want. More on that later.
Satisfied is not engaged - and the difference is everything
A satisfied customer had their expectations met. An engaged customer has an emotional investment. One stays because the switching cost isn't worth it yet. The other stays because they genuinely want to.
Early in my career, I worked with the Conversion Model - a behavioural science framework originally developed to measure religious commitment and later applied to consumer brands. Its central finding was that for commitment to be possible, the choice itself had to feel like a significant personal question. This translates directly to consumer behaviour: what determines commitment is involvement - how important is this category to the customer in the first place?
If a customer is satisfied but the category feels low-stakes - choosing a paperclip brand, picking between two similar utility providers - their loyalty is shallow. One competitor promotion and they're gone. Not because you did anything wrong, but because they never cared that much. I've seen businesses spend millions trying to re-engage customers who were never going to be anything other than transactional. The model explains exactly why.
The implication for your strategy is significant: before you invest in a retention programme, it's worth asking whether the customers you're trying to retain are genuinely capable of being deeply engaged - or whether they were always going to be transactional.
Retention begins before the sale
I consulted for a B2B SaaS company with high churn. They were focused on it, but nothing was working. A quick profile of the churners told me why: they were almost all small businesses that were a poor fit for the product and couldn't afford the service year-round. They'd been acquired because the sales team was caught in the growth trap - chasing monthly targets with cost-effective but poorly-fit leads the marketing team had provided.
The company addressed their churn without changing the customer experience at all. They simply became disciplined about their Ideal Customer Profile (ICP) - a clear definition of who the product is actually built for, accounting for both the customer's needs (does it solve their problem) and the company's (will the customer continue to pay).
Customer acquisition cost went up. Total lifetime revenue went up more.
This is Theodore Levitt's point from Marketing Myopia, still as relevant as when he wrote it: if your product doesn't solve a meaningful, ongoing problem for a customer who can both appreciate and afford it, no amount of service excellence or loyalty investment will create durable engagement. You can't design your way out of a fundamental mismatch. Think of it this way: a Ferrari meets the needs of many people. Most of them can't afford one. The fit has to work both ways.
There's also a dynamic here that doesn't get enough attention: the brand signalling effect. When your positioning sharpens, strong-fit customers feel genuinely seen. Weak-fit customers start to self-select out - not because you pushed them away, but because it's obvious you weren't built for them. Narrowing your focus can grow your business. The discipline to say no to the wrong revenue is one of the most valuable capabilities a business can develop.
The five dimensions of outside in engagement
Customer engagement isn't a single metric or a programme. It's a multi-faceted view of the relationship, and it's built on five things.
1. Making it feel easy
Customers rarely leave after one bad experience. They drift away because interacting with you gradually becomes too much work. Gartner’s Customer Effort Score research shows reducing effort often predicts loyalty better than delight - counterintuitive for businesses chasing “wow moments.”
Boots rebuilt its prescription reordering process after discovering many lapsed loyalty members had simply found it too cumbersome. No complaint. No drama. Just friction compounding. The best retention moves are often the unglamorous ones: fewer steps, faster resolution, clearer pathways to value.
2. Making it feel safe
Without trust, everything else is fragile. Transparent pricing, consistency across touchpoints and responsible data practices aren’t nice-to-haves; they’re structural.
In an AI-driven world, trust is becoming the primary differentiator. Customers often can’t tell whether they’re being helped or managed. Businesses that are explicit about their values - and consistent in living them - build relational equity that competitors can’t easily replicate. And once lost, trust is brutally expensive to rebuild.
3. Making it feel personal
Hyper-personalisation is now baseline. But the real driver isn’t technology - it’s the feeling of being known.
Chewy became famous not for its algorithms but for handwritten sympathy cards sent when customers mentioned a pet had died. Agents were empowered to respond to emotional cues in real time. That human responsiveness generated word-of-mouth more powerful than any acquisition campaign. Context-aware communication signals you’re genuinely paying attention.
4. Making it feel good
Satisfaction is rational. Engagement is emotional. As Joseph Pine argued in The Experience Economy, customers aren’t just buying products - they’re buying a version of themselves.
Shopify doesn’t sell software. It empowers entrepreneurs. That framing shapes the emotional relationship. When you tell the customer’s story rather than your own, price becomes part of a shared journey rather than a negotiation.
5. Making it feel participatory
Engagement compounds when customers become contributors. At Domain, we co-designed the Skylight companion app with real estate agents - then made those agents the heroes of the marketing campaign. The result was a product adoption rate and advocacy level that no conventional launch could have produced.
Feedback loops that visibly close, community and co-creation create ownership. And partners don’t quietly leave.
Six ways to put it into practice
Here are six things worth doing - regardless of your industry, size, or budget.
Audit your ICP against your churners: Analyse your last 12 months of churn and ask honestly: were these customers you should have signed in the first place? If a significant portion were poor ICP fits, the problem isn't your onboarding or your customer experience. It's upstream in sales and marketing. Fix the source, not the symptom.
Build a real-time health score - not just a survey: Stop segmenting by spend or demographics alone. Build a holistic health score from real-time behavioural inputs: feature adoption and login frequency in SaaS; purchase cadence and returns data in retail; support ticket sentiment in any business. A leading indicator of churn is far more valuable than a lagging one - and you’ll have the CFO’s attention when you can show that every one-point increase in health score correlates with $X in additional lifetime value.
Apply the Pareto principle and prioritise your highest-value relationships: Not every customer warrants the same level of attention, and spreading your resources evenly is a false economy. Identify the top segment of your base - the genuine ICPs driving the majority of your revenue - and build a deliberately different model for them. In B2B, that might mean a Customer Success team conducting proactive quarterly business reviews that reinforce ROI. In B2C, it might mean a concierge tier or queue-jumping access. The goal isn't to neglect everyone else; it's to protect what matters most.
Poke the bear. Proactively: High-value customers who go quiet are an opportunity, not a threat. The fear that contacting them will trigger a cancellation is often misplaced. In one programme I ran, simple personalised outreach to inactive accounts saw 50% log back in within a week. For every sleeping giant you occasionally wake and lose, you save multiples more who were silently drifting away. Set up usage-based alerts, assign them to your team, and make the call.
Obsess over the first 100 days: A lot of long-term churn is decided in the onboarding phase - not at renewal. This is where buyer's remorse takes root or genuine commitment is forged. Map every touchpoint in that initial period and ask: does this make the customer feel like they made the right decision? Does it connect them to value, fast? Get this right and the entire retention curve changes.
Tell the customer's story, not yours: Go through your last five customer-facing communications and ask: who is the hero of this story? If it's your product, rewrite it. Your marketing and customer success teams should be articulating what success looks like for the customer - not listing your features. The customer is the hero. You're the guide that helps them get there.
The outside-in shift worth making
Building from the outside in isn't a new idea. Forrester and McKinsey have championed it for years. But knowing the concept and actually organising a business around it are two very different things. Most companies can describe it. Far fewer have made it the lens through which every real decision gets made - who to target, what to measure, where to invest, and whose problem you're actually trying to solve.
The businesses that build something lasting treat customers as long-term assets. Research from Bain & Company shows that increasing customer retention by just 5% can lift profits by 25% to 95%, depending on industry economics. That’s the compounding effect of keeping the right customers longer. And in many businesses, 60% or more of revenue already flows from existing customers. The smart ones invest accordingly. They know an engaged customer is more forgiving when things go wrong, less price sensitive, and your single most effective source of new business.
But beyond the economics - and this is the part I care about most - a business built around the customer is simply a better business to work in. Because when the person opening their wallet is winning, it means you're actually solving something real.
Engagement isn't a programme or a metric. It's what happens when a customer feels heard, valued, and genuinely better off because of you. And it starts long before the sale - with the decision of who you're actually building this for.
