7 Pillars of Building Financial Products That Actually Stick

Building a financial product that users love and keep coming back to is a monumental challenge. Over the years, countless promising ideas have blossomed from zero to hero in weeks, only to wither away within months. The financial sector is especially unforgiving: people entrust their hard-earned money, expectations are sky-high, and competition is fierce. The natural temptation is to throw as many features as possible at the wall, hoping something sticks. But that approach is a recipe for disaster. In this article, we break down the 7 pillars that separate passing fads from bedrock products—stable, user-friendly, and built to last.

1. The Fallacy of Feature-First Development

When starting from scratch or migrating paper-based services to digital, excitement easily leads to a feature-first mindset. Teams pile on capabilities, convinced that each new button will charm users. But reality hits quickly: security teams (the "narcs") may reject a design, a feature might flop with users, or unforeseen complexity breaks everything. This scattergun approach creates a messy, confusing experience—a "feature salad" that no one loves. Instead of solving a core problem, the product becomes a reflection of internal politics, not customer needs. To avoid this trap, you must ruthlessly prioritize. Ask: What is the one thing users cannot do without? Building around that single value is far more powerful than adding a hundred half-baked extras.

2. The Minimum Viable Product: Less Is More

The concept of the Minimum Viable Product (MVP) is deceptively simple: deliver just enough value to solve a real user problem, and nothing more. Popularized by thinkers like Jason Fried (Getting Real), MVP requires a razor-sharp eye and the courage to say no. In financial products, an MVP might be a basic account view, a simple transfer, or a clear transaction history. It doesn't need fancy charts or AI-driven insights. What it needs is reliability and focus. Many teams confuse MVP with "half-baked"—but a true MVP provides a complete, valuable experience in its narrow scope. It's the foundation upon which you can later build, but only after validation. Without an MVP, you risk spending months on features that nobody actually uses.

3. Beware the Columbo Effect: The Curse of "Just One More Thing"

There's a seductive pull in product development, famously called the Columbo Effect: the endless cry of "just one more thing." A stakeholder suggests a small addition, then another, and suddenly your clean MVP is bloated with compromises. This feature creep destroys usability and stability. Every new feature introduces complexity, security risks, and maintenance costs. In retail banking, for instance, adding a budget tracker might seem harmless, but soon it pulls in external data feeds, regulatory checks, and UI headaches. The result? A sluggish app that tries to do everything but masters nothing. To fight the Columbo Effect, keep a strict product roadmap and validate each addition against the core user need. If it doesn't strengthen the bedrock, don't add it.

4. Internal Politics: The Hidden Enemy of Great Products

Many financial apps end up as a messy reflection of the company's internal struggles. Different departments—marketing, risk, operations—each demand features to satisfy their own metrics. The product becomes a battleground where the loudest internal voice wins, not the customer. The result is a disjointed experience that tries to serve everyone and pleases no one. For example, a current account might get a credit card upsell (pushed by the credit team) and a savings goal tracker (pushed by wealth management) even though the user just wants a simple transaction log. To break free, start with the customer's primary journey—the bedrock—and shield it from internal politics. Every feature proposal must pass one test: Does this solve a core user problem or just an internal agenda?

5. The Bedrock Principle: Build Around What Truly Matters

So what is the "bedrock" of a financial product? It's the core element that provides enduring value and keeps users engaged day after day. For retail banking, that bedrock is regular servicing journeys: checking balances, viewing transactions, making payments. People may open a current account once but interact with it daily. If this bedrock experience is solid—fast, accurate, intuitive—you earn trust and loyalty. Fancy features like savings calculators or investment tips are decorative; the bedrock is structural. Identify your product's bedrock early. Simplify it. Polish it. Resist the temptation to bury it under layers of novelty. A strong bedrock doesn't just stick; it becomes a daily habit for users, making your product indispensable.

6. From Beta to Bedrock: A Framework for Lasting Products

Building products that stick isn't about trying everything and hoping something works. It's a deliberate process: start with a clear vision of the user's most essential need (the bedrock). Build an MVP around that need. Shield it from feature creep and internal politics. Once validated, iterate carefully, always checking new features against the bedrock's integrity. This framework turns a fragile beta into a robust, beloved product. In the financial world, where trust is currency, a stable and focused experience wins over a feature-packed mess. Remember: your product doesn't need to be the biggest; it needs to be the most reliable. That's how you go from beta to bedrock—and stay there.

Building financial products that last is hard, but the principles are clear. Avoid the trap of feature-first thinking. Embrace the MVP mindset. Guard against the Columbo Effect. Keep internal politics in check. Find and protect your bedrock. And always, always build around what truly matters to the user. These 7 pillars are not just theory—they're a practical guide to creating products that users don't just try, but adopt and defend. The next time you're tempted to add "just one more thing," pause. Ask yourself: Is this strengthening the bedrock or just piling on pebbles? Your users—and your product's longevity—will thank you.
