Industry Expert Warns: Feature-Heavy Finance Apps Are Doomed to Fail, Advocates 'Bedrock' Approach

A seasoned product developer with decades in financial technology warns that the common strategy of piling features onto banking apps is a recipe for disaster, leading to user frustration and rapid abandonment. Speaking anonymously, the expert argues that most financial products fail within months because they prioritize internal politics over customer needs.

The Pitfalls of Feature-First Development

“When you start building a financial product, it’s tempting to add just one more feature to solve a user problem,” the expert said. “But then the security team rejects it, or it’s less popular than expected, or complexity breaks it. That’s how promising ideas fizzle out.”

This phenomenon, common in retail banking and fintech, results in apps that are “a reflection of internal business politics rather than an experience designed around the customer,” the expert explained. The focus shifts to satisfying competing internal departments, creating what he calls a “feature salad”—a confusing, unlovable mix of functionalities.

The expert, who has worked on both new product builds and migrations from paper and telephony to digital channels, notes that the Minimum Viable Product (MVP) concept is often misunderstood. “Jason Fried talks about building just enough value—not too much. But it’s hard to resist the ‘Columbo Effect’: the urge to add ‘just one more thing.’” He stresses that an MVP requires a “razor-sharp eye and ruthless courage” to stick to essentials.

Background: The Roots of Feature Bloat

The financial sector is particularly vulnerable to feature bloat because user expectations are high and the market is crowded. “With people’s real money on the line, companies try to outdo competitors by throwing features at the wall,” the expert said. This leads to apps that are overwhelming to maintain and fail to provide a clear value proposition.

Over many years, the expert has watched countless ideas go “from zero to hero in weeks, only to fizzle out within months.” The pattern is consistent: initial excitement gives way to roadblocks from security teams, unpopular features, or unforeseen complexity.

The Importance of 'Bedrock'

To build products that stick, the expert advocates for a “bedrock” approach. “Bedrock is the core element that truly matters to users—the fundamental building block that provides lasting value,” he said. In retail banking, the bedrock is “regular servicing journeys” such as daily account checking. “People open a current account once in a blue moon, but they look at it every day. That’s where you need to excel.”

Key elements of the bedrock strategy:

• Identify the single most important user need and focus on it ruthlessly.
• Resist the urge to add features that satisfy internal departments.
• Prioritize stability and simplicity over novelty.

The expert contrasts this with feature-first development: “Bedrock means building a product that is stable, user-friendly, and relevant over time. Feature-first builds products that are fragile, confusing, and short-lived.”

What This Means for Fintech and Banking

The warning comes at a time when digital banking is exploding, with new apps launching weekly. “If you want your product to survive beyond the launch hype, find your bedrock and build from there,” the expert advises. Companies that ignore this risk creating a “mixed bag of confusing experiences” that users will abandon.

For product managers and developers, the takeaway is clear: resist internal pressure to bloat features. As the expert puts it, “It’s easy to be seduced by the ‘one more thing’ mentality, but the winners are those who have the courage to stop.”
