Financial services has traditionally been a slow-moving beast-built for stability, not speed. But with disruptors flooding the market, that’s changing quickly. 

On one side are the established players: banks, insurers, and wealth managers built on decades-sometimes centuries-of trust, scale, and regulatory discipline. On the other, a wave of fintech challengers rewriting the rules of how financial products are built, delivered, and, crucially, marketed. 

Both are chasing the same outcome: trust, acquisition, and long-term customer value. But historically, they’ve taken very different routes to get there. What’s changing now is that the gap between them is starting to close.

Defining the Difference

Legacy financial services brands were built around stability-and their marketing reflects it. Structured, consistent, and often product-led, it reinforces credibility at scale, leaning heavily on brand equity and long-standing relationships.

Fintechs took a different path. Digital-first and customer-led, they’ve prioritised usability, speed, and clarity. Rather than asking customers to trust their track record, they earn trust through experience-better interfaces, simpler messaging, and more relevant interactions.

Two very different starting points. Increasingly, though, they’re solving for the same problems.

Trust Is Still the Game 

Whether you’re a global bank or a three-year-old fintech, trust remains non-negotiable. 

Financial decisions are high-stakes, long-term, and often emotional. At the same time, regulatory pressure continues to increase-particularly in the UK, where frameworks like FCA Consumer Duty are forcing marketers to rethink clarity, fairness, and customer outcomes. 

Customers now expect transparency, consistency, and evidence that brands are acting in their best interest. 

That’s the baseline-not the differentiator. 

The Legacy Playbook: Built for Scale 

Traditional institutions have approached marketing through the lens of scale and control. 

Brand has been the primary lever-supported by large campaigns, sponsorships, and above-the-line activity designed to reinforce credibility across broad audiences. Messaging is tightly managed, often product-centric, and shaped by compliance as much as creativity. 

The upside is trust and consistency at scale. The trade-off is agility. 

Long campaign cycles, cautious tone of voice, and limited experimentation weren’t problems in a slower market-but they’re friction in one where expectations are shifting in real time. 

The Fintech Playbook: Built for Momentum 

Fintechs flipped the model. 

Instead of leading with products, they start with the customer-their frustrations, motivations, and real-world use cases. Marketing is simpler, clearer, and often more educational. It’s less about features, more about outcomes. 

Their channel mix reflects that. Rather than campaign bursts, fintechs operate in an always-on model-across paid social, in-app journeys, push notifications, and, critically, email. Engagement isn’t periodic; it’s continuous. 

Brand plays a different role too. It’s not just identity-it’s personality. The challengers breaking through are more human, more transparent, and more conversational. They’ve made financial services feel, well… less like financial services. 

And because they’re not weighed down by legacy systems or processes, they move faster. Test more. Learn quicker. 

That speed compounds. 

Where It Gets Interesting: Convergence 

The real story now isn’t the difference between legacy and fintech-it’s the convergence. 

Legacy institutions are investing heavily in digital experience, lifecycle marketing, and owned content. They’re starting to think more like media companies-building ongoing relationships rather than running isolated campaigns. 

At the same time, fintechs are maturing. Growth-at-all-costs is giving way to a sharper focus on profitability, brand building, and regulatory discipline. In other words, they’re adopting the very characteristics they once disrupted. 

Both sides are evolving-just from opposite directions. 

The Real Battleground: Owned Audience 

This convergence becomes most obvious in owned audience strategy. 

We’re operating in a landscape defined by declining organic reach, rising acquisition costs, and the early signs of AI reshaping how people discover information. “Google Zero” isn’t theoretical anymore. 

In that environment, rented channels become fragile. 

Owning the customer relationship becomes critical. 

That means investing in channels like email-not as a campaign tool, but as a core engagement layer. It means building first-party data strategies that go beyond segmentation into true personalisation. And it means shifting from funnel thinking (lead → conversion) to lifecycle thinking (relationship → value → retention). 

This is where the dynamic sharpens. 

Legacy brands have the advantage of scale-deep data and established customer bases.
Fintechs have the advantage of execution-the playbooks, tooling, and mindset to activate that data. 

The winners will be the ones who can combine both. 

What This Means for Marketers 

The takeaway isn’t that one model wins-it’s that both are being forced to evolve. 

Trust is now table stakes. If your marketing starts and ends with compliance-led messaging, you’ll struggle to stand out. 

Owned channels are becoming mission-critical. Over-reliance on paid acquisition or search isn’t a strategy-it’s a risk. 

And perhaps most importantly, marketing needs to be treated like a product. Not something you launch and leave, but something you continuously refine based on real user behaviour. 

Final Thought 

This isn’t a story of old versus new. It’s a story of adaptation. 

Legacy players are learning how to move faster and engage more meaningfully. Fintechs are learning how to build deeper, more durable trust. 

Somewhere in the middle, a new model of financial services marketing is emerging-one that blends credibility, creativity, and genuinely customer-centric thinking. 

The question isn’t who started ahead. It’s who executes best from here.
