How Fintech Companies Can Use Rapid Experimentation to Grow

Fintech companies operate in a financial environment where customer expectations, payment behaviors and access to financial services continue to evolve. Yet developing new products and features does not necessarily translate into meaningful innovation. Companies must understand which problems customers need solved, where existing financial services fall short and which improvements deliver measurable results.

Rapid experimentation gives fintech leaders a practical way to answer those questions before committing significant resources to a full-scale launch. By testing assumptions, gathering customer feedback and evaluating real-world results, companies can identify opportunities to improve products, streamline operations and reach underserved markets.

Members of the Senior Executive FinTech Think Tank, a curated group of financial technology professionals and business leaders, share where experimentation can create the greatest value. Their insights point to four particularly promising areas: understanding changing consumer needs, improving payment operations, reducing friction in customer communications and expanding access to credit through more personalized financial solutions.

Start With Changing Customer Needs, Not Product Assumptions

One of the most valuable applications of rapid experimentation is discovering how financial needs change over time. Fintech companies can develop products around assumptions about customer behavior, but those assumptions may become outdated as economic circumstances, household structures and financial priorities shift.

Banu Raghuraman, AI Lead Product Manager at Perficient, brings more than 15 years of experience developing customer experiences and software solutions, primarily across fintech, payments and healthcare. She has led product MVPs for mobile banking, real-time payments and conversational intelligence solutions. Her product development and financial technology experience informs her view on why companies should make customer research central to experimentation.

“Apply rapid experimentation to understand customer needs and preferences,” Raghuraman says. She emphasizes that financial products must evolve alongside the people they serve and not remain tied to outdated expectations.

For example, traditional financial products have often been designed around familiar milestones, such as purchasing a home, paying off a mortgage during one’s working years and building retirement savings. However, those expectations do not necessarily reflect the financial realities of younger generations or households facing different economic pressures.

Raghuraman highlights the contrast between “a society that managed to pay off mortgages during their earning years” and “a generation of lifetime renters.” The changing circumstances illustrate why financial institutions cannot assume yesterday’s customer profiles will accurately represent tomorrow’s markets.

The Federal Reserve’s May 2026 Report on the Economic Well-Being of U.S. Households in 2025 offers additional context. Although 73% of adults reported that they were doing okay or living comfortably financially, 91% identified price increases as either a major or minor financial concern. The report also found that only 63% could cover a hypothetical $400 emergency expense exclusively with cash or its equivalent. These findings illustrate the different financial pressures product teams should consider when evaluating customer needs.

For fintech companies, the opportunity is to turn those changing circumstances into specific research questions. Are customers struggling to qualify for traditional credit? Are existing savings products aligned with their financial priorities? Do renters need different tools to manage housing expenses or prepare for homeownership?

Rather than relying exclusively on historical transaction data or broad demographic categories, product teams can interview customers, test early concepts and compare responses across different customer segments.

Raghuraman stresses the importance of understanding “the true needs and state of the layers of society” to ensure financial institutions are targeting the right populations. This means treating experimentation as an ongoing discovery process rather than a one-time exercise conducted before a product launch.

Improve Payment Operations and Cash Flow Through Small Experiments

While understanding consumer needs helps fintech companies develop more relevant products, experimentation can also create immediate value by addressing operational inefficiencies. Payments, collections, merchant onboarding and fraud prevention offer opportunities to test targeted improvements that produce tangible business results.

Allen Kopelman, CEO of Nationwide Payment Systems Inc., has worked in payments since founding the company in 2001. Nationwide Payment Systems serves businesses across the United States, including retail, restaurants and hospitality, B2B and wholesale, e-commerce, SaaS platforms and complex payment environments.

From his perspective, rapid experimentation creates the greatest value when it addresses practical business challenges rather than simply introducing another technology feature.

“Rapid experimentation creates the greatest value in fintech when it solves real business problems, reduces costs and improves cash flow,” Kopelman says.

He identifies several promising areas, including payment optimization, embedded finance, AI-driven automation and customer experience. These opportunities give fintech companies multiple ways to test improvements without requiring an entirely new product or infrastructure.

For example, a payment provider could experiment with smarter invoicing to determine whether clearer billing information helps customers pay faster. Another test might compare ACH alternatives or commercial card options to identify which methods offer better economics for specific business segments. Companies should evaluate automated fraud-prevention tools to determine whether they reduce losses without introducing unnecessary transaction declines.

These experiments must be designed around measurable outcomes. A faster payment process may be limited in value if it creates more reconciliation work or increases operational costs elsewhere. Similarly, an automated underwriting process may reduce processing time but still require refinement if it creates inconsistent customer experiences.

Kopelman also highlights merchant onboarding, underwriting and integrations as areas where experimentation can simplify business operations. These processes can involve multiple steps, systems and approvals, creating opportunities to identify unnecessary delays and improve the merchant experience.

“Technology should make doing business easier, not more complicated,” he says.

That principle is particularly important when fintech companies serve small businesses that may lack dedicated technology or finance teams. Simplifying an integration or reducing the time required to activate a merchant account can create value without introducing a complicated new service.

Kopelman also cautions against assuming that meaningful innovation must be revolutionary. “Small improvements that save businesses money, accelerate payments and eliminate friction can create significant competitive advantages,” he says.

For fintech leaders, the lesson is to prioritize experiments that connect directly to business performance. Rather than measuring success by the number of features introduced, companies should evaluate whether a change improves cash flow, lowers processing costs, reduces fraud or makes operations more efficient.

Mastercard research reinforces the value in this approach. In its October 2026 analysis, Test and Learn in Banking: An Explainer for Financial Institutions, Mastercard reports that 86% of financial institutions struggle to balance innovation with risk, while 78% say testing innovations on a smaller scale before full rollout would help. Controlled experiments can help fintech leaders distinguish an initiative from other market changes and determine which improvements warrant broader implementation.

Reduce Customer Uncertainty Through Better Payment Communication

Not every valuable fintech experiment requires changes to payment infrastructure, underwriting models or product functionality. Sometimes, the greatest opportunity is improving how a company communicates with customers during an existing financial process.

Faturoti Kayode, an internet entrepreneur and Co-Founder of Breet, highlights payment-status communication as an especially useful starting point. His experience building financial technology businesses gives him a perspective on the importance of making digital financial services easier for customers to navigate.

Through Breet, a cryptocurrency and payment infrastructure platform, businesses and individuals across Africa can spend cryptocurrency instantly. Kayode recommends beginning with a relatively contained experiment: testing how customers respond to clearer explanations when a transfer is pending.

“Start experimenting with payment-status messages,” he says.

A pending payment can create uncertainty, especially when customers do not know whether a transaction is progressing normally, requires additional action or has encountered a problem. Even when the underlying payment process works as intended, unclear communication can generate frustration and additional support requests.

For fintech companies, this creates an opportunity to test different message formats and explanations without changing the underlying rules governing money movement.

A company might compare a generic pending-transfer notification with a more informative message explaining the current status and what the customer should expect next. Another test could evaluate whether a clearer explanation of processing steps helps customers understand why a transfer is not completed.

The key is to measure whether the communication actually improves the experience. Kayode recommends testing with a small customer group and evaluating whether users understand the next step and require fewer support contacts.

“Measure whether they understand the next step and need fewer support contacts,” he says.

These metrics can help product teams determine whether the revised messaging reduces confusion. Companies can also examine repeat inquiries, support ticket volume and customer feedback to identify where explanations remain unclear.

More importantly, this type of experimentation does not require a company to alter its settlement processes, transaction rules or compliance obligations. Instead, it focuses on making the existing experience easier to understand.

Kayode’s approach also demonstrates why fintech leaders should not overlook relatively small customer-facing improvements. A payment-status message may seem minor compared with a new financial product, but it may influence how customers perceive the reliability and transparency of the entire platform.

Expand Credit Access Through Alternative Decisioning and Financial Education

Rapid experimentation can also create significant opportunities in credit decisioning and financial education, particularly when traditional financial models fail to account for the circumstances of underserved consumers and small businesses.

Reco McCambry, Founder, President and CEO of Novae, offers experience in financial technology, consumer credit and entrepreneurship. Novae provides access to credit, capital and financial resources through consumer financing, commercial lending access, credit management software, tax solutions and career development programs. 

McCambry sees alternative credit decisioning and personalized financial education as two areas where fintech companies can identify opportunities traditional financial institutions may overlook.

“Rapid experimentation creates immense value in alternative credit decisioning and personalized financial education,” he says.

Traditional credit decisioning can leave gaps in access, particularly for consumers and entrepreneurs whose financial circumstances do not fit conventional lending models. Fintech companies can experiment with additional data models and decisioning approaches to better understand these populations and identify opportunities to serve them responsibly.

For example, companies could test whether alternative data points offer useful insights into applicants with limited traditional credit histories. They could also evaluate whether different combinations of financial education and credit management tools help customers better understand their borrowing options and improve their financial preparedness.

The key is to approach these experiments with appropriate safeguards. Evaluate alternative data and new decisioning models for accuracy, consistency and potential discriminatory effects. Companies must also ensure testing does not compromise customer privacy or introduce unfair lending outcomes.

McCambry stresses the opportunity to use experimentation to “identify underserved markets and deploy microsolutions that traditional banks ignore.” Rather than assuming that a single financial product will address every customer’s circumstances, fintech companies can test smaller, more targeted solutions and determine which ones demonstrate meaningful demand.

This approach can also help leaders respond to changing market conditions. Testing new data models and customer solutions lets companies evaluate emerging opportunities without immediately committing to large-scale product development.

McCambry emphasizes that this agility helps fintech leaders “iterate through market turbulence” while ensuring their products address immediate consumer needs.

Personalized financial education offers another opportunity. Companies can experiment with different educational formats, communication methods and product recommendations to determine which approaches help customers understand their financial options. The objective is to provide more information that is relevant and useful to the individual.

For fintech executives, the opportunity lies in connecting experimentation with responsible financial inclusion. Identifying an underserved market is only the beginning. Companies must also demonstrate that their solutions are appropriate, accessible and capable of producing sustainable outcomes.

Practical Ways to Turn Fintech Experiments Into Business Results

• Research changing customer needs before developing new products. Interview customers, study evolving financial circumstances and test product concepts to identify underserved populations and unmet needs.
• Prioritize experiments that improve payment operations and cash flow. Test smarter invoicing, faster collections, ACH alternatives, commercial card optimization, fraud prevention and simpler merchant onboarding.
• Make payment communications clearer and more useful. Test alternative explanations of pending transactions with a small customer group and measure whether customers better understand the next steps and require fewer support contacts.
• Experiment with alternative credit decisioning and personalized financial education. Test new data models and targeted financial solutions to identify underserved markets and address consumers’ immediate financial needs.

Make Experimentation a Continuous Competitive Advantage

Rapid experimentation enables fintech companies to innovate with greater focus and less reliance on assumptions. Whether the opportunity involves understanding changing consumer needs, improving payment operations, reducing customer uncertainty or expanding access to credit, targeted testing can help leaders determine where their resources will have the greatest impact.

The most effective approach does not necessarily require launching more products or introducing increasingly complex technology. Instead, it involves asking better questions, testing practical solutions and measuring whether they make a meaningful difference. As financial needs and customer expectations evolve, fintech companies that make experimentation a consistent part of their product and business strategies will be better positioned to identify opportunities, respond to market changes and deliver lasting value.
