The Evolution of Customer Marketing: From Generic CX to Revenue Champs

Customer marketing has evolved from reactive customer experience work to a strategic, revenue-driving function — and the math makes it obvious why. In a thought-provoking Obsession session, Lisa Nakano, VP of Customer Engagement Strategies at Forrester, traced that evolution and laid out a roadmap for today's customer marketers. Here's the recap.

The evolution of customer marketing

Customer marketing's journey began with customer experience initiatives that were largely reactive — focused on problem-solving rather than creating proactive, value-driven relationships. Early efforts centered on mapping customer journeys and implementing voice-of-the-customer programs. While these laid the groundwork, they often lacked measurable impact.

Over time, CX evolved into customer success (CS) as businesses shifted to recurring revenue models. Companies recognized that keeping customers engaged and satisfied was essential for growth. Customer success brought operational discipline to post-sale efforts but also faced challenges, particularly when it stretched into shadow marketing activities like newsletters and events without a clear strategy.

The rise of customer marketing marked a turning point. With a focus on advocacy, retention, and growth, customer marketing emerged as a critical function capable of driving measurable revenue impact. As Nakano put it: "Customer marketing moved from being reactive to becoming a strategic partner in the organization."

Why the financial case for customer marketing is now overwhelming

The data backs the shift:

• McKinsey's analysis of 100+ B2B SaaS companies found Net Revenue Retention is the single metric most correlated with enterprise value — top-quartile valuations averaged 24x revenue vs. 5x for the bottom.
• Companies with sophisticated value-realization and adoption journeys produce NRR roughly 7 percentage points higher than peers with basic practices (McKinsey, 2025).
• Best-in-class B2B SaaS firms generate more than 50% of new ARR from expansion — not new logos.
• 62% of B2B companies now prioritize upsell and cross-sell as core growth strategies (Responsive, 2025).

That's why CMOs who used to be measured only on new logos are now compensated on retention and expansion. Customer marketing is the function closest to that signal.

The post-sale ecosystem: building an integrated model

Nakano emphasized the importance of integrating customer experience, customer success, and customer marketing into a cohesive post-sale ecosystem:

"In a perfect world, these three functions work together seamlessly. That's when you have a healthy, dynamic environment that delivers real impact."

In practice, that integration involves:

• Shared metrics: All teams contribute to retention, profit, and growth — business impact, not siloed activities.
• Cross-functional collaboration: Customer marketers work with product, finance, and demand gen to amplify impact.
• Customer personas: Distinguish buyer personas from user personas so post-sale programs address each group's unique needs.

Base's Team Dashboards are designed precisely for this kind of cross-functional alignment — putting a single view of the customer in front of Marketing, Sales, and CS.

From CX to revenue champs: overcoming common pitfalls

Nakano identified several challenges customer marketers face as they establish their value:

1. Focusing too quickly on upsells. Don't dive into cross-sell and upsell immediately after purchase. Build trust and deliver value first — see our post on driving upsell and expansion through customer-centric campaigns.
2. Disconnected metrics. Many CS and marketing teams struggle with metrics that don't align with business goals. Health scores with too many components or metrics tied to activity rather than impact dilute program effectiveness.
3. Overstretching teams. Customer marketers must learn to say no when asked to take on tasks outside scope, so they can focus on high-impact initiatives.

The rise of customer marketing as a strategic function

The tides are turning. Nakano pointed to several trends fueling the rise:

• CMO accountability. Modern CMOs are increasingly measured on retention and growth, making customer marketing a priority.
• Demand marketing synergy. Demand gen teams recognize the value of partnering with customer marketers — because existing customers drive faster, larger deals.
• Recurring revenue everywhere. Industries beyond SaaS — manufacturing, medical devices — are adopting recurring revenue strategies, creating opportunities for customer marketers to play pivotal roles.

"Recurring revenue models are everywhere. Customer marketers are essential for keeping clients engaged throughout the lifecycle."

What makes a great customer marketer?

• A long-term mindset. Unlike demand marketers, customer marketers build lifelong relationships with customers.
• Cross-functional fluency. Great customer marketers speak the language of product, finance, and sales.
• Scrappiness and creativity. Given limited resources, they find ways to do more with less.
• Collaborative spirit. Success comes from helping others shine — enabling product with customer insights, supporting sales with advocacy programs.

Final thoughts: from silos to strategic impact

As customer marketing continues to evolve, its potential to drive revenue and retention has never been greater. By adopting an integrated, metrics-driven approach, customer marketers can transform from support players to revenue champions.

In Nakano's words: "The best customer marketers are scrappy, collaborative, and focused on long-term impact. They're the ones driving real change in their organizations."

Frequently asked questions

What is the difference between customer experience, customer success, and customer marketing?

Customer experience is the reactive discipline of mapping and improving what customers encounter across their journey. Customer success is the operational function that drives adoption, retention, and outcomes. Customer marketing is the strategic function that turns existing customers into retention, expansion, and advocacy revenue — owning the programs and the measurable business impact.

Why is customer marketing now considered a revenue function?

Because the post-sale relationship is where most of the money now comes from. Best-in-class B2B SaaS firms generate over 50% of new ARR from expansion, and McKinsey finds NRR is the single metric most correlated with enterprise value. Customer marketing sits on top of the signals — reviews, references, advocacy, adoption — that convert those stats into actual revenue.

What metrics should customer marketers own?

Net Revenue Retention, Customer Lifetime Value, advocacy participation rate, reference velocity, expansion pipeline generated, review volume, and retention rate. These are the numbers that tie customer marketing activity directly to CFO-visible revenue.

What background makes a great customer marketer?

There's no single path. Nakano's profile skews toward long-term thinkers with cross-functional fluency — people who speak product, finance, and sales — combined with scrappiness, creativity, and a collaborative instinct to help other teams shine.
