Since its official launch in 2017, Flutter has seen exponential growth in usage, accounting for 30%1 of new apps in the Play and App Store. Its high-performing capabilities, modern widget-based UI development, and a mature ecosystem of plugins and packages make it the perfect choice for complex environments where time to market, customer satisfaction and innovation are at the center of the business.
Choosing a hybrid or multi-platform solution should come from a thoughtful evaluation of your product’s needs. At Very Good Ventures (VGV), we believe the right approach depends on the project, which is why we work closely with clients to identify the best tools for their unique goals. Whether it’s a full Flutter build or a hybrid architecture using native plugins, we guide product teams through smart, future-ready decisions that support flexibility, scalability, and long-term success.
But when it comes to Flutter for fintechs, there's a common myth we still hear: that native development is the only way to go because of performance or hardware features.
Luckily, we’re here to set the record straight. We know that security, performance, and reliability are everything for fintechs—and we know that Flutter’s right for the job. Read on to see how far your fintech can go with the power of Flutter.
Multi-Platform Powers
Here’s the truth: the idea that only native development can handle fintech-level demands is outdated. Today’s multi-platform tools—especially Flutter—can power secure, robust, feature-rich applications without sacrificing usability or visual quality.
As the leading Flutter agency, we build high-performance, scalable apps from a single codebase, reducing costs while expanding reach. Our close partnership with Google ensures we push Flutter’s boundaries to deliver seamless, future-ready apps.
Leading financial institutions like Tide (business banking), Google Pay, VISA, GEICO, and Credit Agricole Bank Polska didn’t choose Flutter because of hype; they chose it because it delivers on the three pillars of fintech success: speed, performance, and scalable efficiency.
From our proven experience, the end-user can’t tell the difference between a well-built native app and a Flutter app. When it comes to using device-specific capabilities like Face ID, biometrics, Apple Pay, and NFC, Flutter has robust plugin support. And for features not supported out of the box, you can always build custom native plugins while still maintaining the speed and flexibility of a Flutter codebase.
One Codebase, Limitless Opportunities
In a fast moving, security-focused industry like fintech, choosing the right technology is a strategic decision. Flutter stands out by combining native performance, design flexibility, and faster development into a single, scalable platform. With one codebase, fintech teams can deliver high-quality apps for iOS and Android, accelerate time to market, and maintain consistency across platforms.
Unlike frameworks that rely on bridges or native components, Flutter compiles directly to machine code, ensuring smooth performance and reliability. Its robust tooling and modular architecture empower teams to iterate quickly and manage design systems effectively, without compromising on security or user experience.
In a nutshell, this is why Flutter works for fintech:
- Accelerated development with a single codebase for iOS and Android
- Consistent, customizable UI with pixel-level control
- Lower development and maintenance costs
- Secure integrations like Face ID, NFC, Apple Pay, and Google Pay
- Built-in testing tools for efficient QA and delivery
- Scalable architecture built for long-term growth
Real Flutter Success Stories In Fintech
Here are some proven outcomes from industry leaders embracing multi-platform development. Check them out:
Dow Jones: MarketWatch Virtual Stock Exchange
Faced with a tight 3-month deadline, Dow Jones needed to bring their Virtual Stock Exchange to mobile while reducing development costs. Using Flutter, VGV delivered a high-performance, multi-platform app 50% faster and at half the cost of native.
The result: an engaging, scalable, education-focused product that’s ready to grow.
“Thanks to Flutter and VGV, we delivered on our goal of building a fun, engaging, and performant app for all screens and mobile devices in significantly less time and cost than if we built it natively,” - Clarence Kwei, SVP Consumer Technology, DOW JONES

Betterment: Scaling Architecture for a Mobile-First Future
As Betterment shifted to a mobile-first strategy, Flutter offered a flexible path. Instead of a full rebuild, VGV integrated Flutter into their existing native codebase. With hands-on training, the internal team quickly gained confidence, enabling a smooth transition toward scalable mobile development.
“We really just liked the experience of Flutter(…)the libraries that came out of the box, the widgets, the component sets (…) it accelerated our development,” - Sam Moore, VP of Architecture at Betterment.

Nav Technologies: Enabling Mobile-First for Small Business Owners
Nav wanted to modernize their mobile app for time-strapped business owners. With VGV’s partnership, they updated to the latest Flutter version, rebuilt mobile architecture, and rolled out new features at a consistent two-week cadence. Nav saw their registered mobile user base double, while empowering other teams to build on mobile.
“Where the app is, we can really accelerate the kind of features that we want. We are now called the Mobile Foundations Team. We are creating the basis for all the other vertical teams to start building on mobile. Now we are populating our skills to other teams, and they will start building directly on the mobile app,” - Zain Khan, Head of Product at Nav.

How Nubank and Global Fintechs Are Winning with Flutter
Nubank, Latin America's largest fintech bank, adopted Flutter to scale mobile development for over 100 million users, tackling inefficiencies in native development that slowed innovation and feature delivery.
Coupled with their use of Server-Driven UI (SDUI), Nubank built a modular, scalable architecture that allows real-time updates and continuous delivery without relying on app store releases. The combination of Flutter and SDUI has enabled Nubank to accelerate iteration, streamline collaboration across teams, and deliver seamless experiences at a massive scale.
"Imagine if every time you needed to build a new screen, you had to touch mobile, backend, database, and infrastructure. That’s not scalable. What if instead, you had high-level platforms that abstract away all the complexity?" - Thiago Ghisi, Director of Engineering at Nubank.
