These elements represent the fintech industry, as the article focuses on choosing the right fintech software development company.

New technologies impose challenges on players in the financial sector. In 2024, the attention remains focused on the influence of artificial intelligence (AI) across all sectors, not only financial ones. In the landscape of perpetual digital evolution, entrepreneurs must keep up with the pace to avoid eventually finding themselves on the market’s periphery. Blockchain transactions, AI integrations, Buy Now Pay Later, biometrics, neobanking, big data, data analytics, and more — how does one handle implementing all these trends in their software?

Hiring an internal team of fintech developers can be one solution. However, this path is more suitable for large companies that have been in the market for years. Even then, the need for specific, up-to-date expertise might emerge. At that point, it’s crucial to search for a reliable vendor that can build the required fintech solutions which are competitive and meet modern standards.

In this article, we’ll provide a list of fintech software development companies with experience in building fintech products, making them worthy of consideration for building your next website or app project. The companies are arranged in alphabetical order. At the end of the article, you will find a short guide to choosing a suitable custom fintech software development company. However, let’s start with a general overview of the fintech market and look at the trends in the field.

Looking for fintech developers? Start your business digital transformation with our professional team.

Fintech market in 2024

According to S&P Global analysis, 2024 is expected to be a return-to-business year, especially for banks and enterprises seeking to modernize their services. Taking into account that 2023 was short on funding and only highlighted the difference between those who found product-market fit and those who did not, there might be intense competition next year

Despite the tightness of funding, the demand for real-time payments innovations in the B2B sector and migration to the ISO 20022 standard makes companies in the banking industry keep up with digital transformation. The technologies that fintech development companies are likely to build for their clients in 2024-2025 will largely focus on real-time payments implementation and cross-border payment navigation, based on the ISO 20022 standard.

A bar chart showing how entrepreneurs in 2023 planned to invest in fintech software development in 2024. 14% planned to significantly increase their investment, 65% planned to slightly increase investment, 13% planned to keep investment the same, 2% planned to slightly decrease investment (by 1%-9%), 1% planned to significantly decrease investment (by 10% or more), and 5% were unsure.

Statista analysis shows steady growth in areas such as digital assets, digital capital raising, digital investment, digital payments, and neobanking. The rapid development of these technologies has been driven by several factors. The first factor is smartphone adoption — people tend to perform transactions with their phones more nowadays. Additionally, the pandemic has accelerated the adoption of contactless transactions, which are now incorporated into modern lifestyles. Regulations have evolved, enabling neobanks to compete with traditional institutions. Lastly, blockchain and AI have offered new opportunities for the fintech business.

A chart depicting the escalating transaction value across various fintech segments. The most significant growth is observed in the neobanking and digital payments sectors. While digital capital raising occupies the third position, it demonstrates a less substantial increase in value. Neobanking witnessed a rise from $0.23 trillion in 2017 to $6.37 trillion in 2024, while digital payments expanded from $3.57 trillion to $11.55 trillion during the same period. Digital capital raising experienced a modest growth from $0.06 trillion to $0.07 trillion.

Let’s briefly describe the trending technologies:

Digital assets

This term describes value recorded on blockchain technology. It refers to property stored exclusively electronically and exchange associated with this property. In the context of the fintech industry, this includes digital currency, stablecoins, and investment contracts.

Digital capital raising

This financial technology refers to the alternative forms of raising money. Digital capital raising platforms help users to raise funds without relying on venture capital and bank loans. Models offered by such platforms include peer-to-peer lending, crowdfunding, and initial coin offerings. According to Statista, the most popular model among these is crowdfunding.

Digital investment

Digital investment platforms allow users to buy and sell financial assets such as stocks, cryptocurrencies, ETFs and more. The most trending technology in this field is robo-advisors, which help users to manage their portfolios and provide investment recommendations via automated algorithms.

Digital payments

These technologies allow for payment without using cash. Digital payments are associated with technologies such as contactless payments, online banking transfers, mobile wallets, and biometric payments. These transactions are primarily performed with digital devices such as smartphones.

Neobanking

Neobanks are new types of banks that do not have physical branches and operate exclusively online. By 2028, the number of neobanking users is expected to reach approximately 386.30 million worldwide.

Data analytics

Custom fintech software development not only helps to enhance customer experiences but also provides valuable insights into a company's processes through data analytics. For example, a company can use data analytics to determine if the financial technology implemented in an application has increased sales conversions. Data analytics platform development might involve AI capabilities, machine learning, and data visualization tools — anything that helps provide valuable insights.

Despite the digital trends in fintech software development, S&P Global reports that 46% of small and medium sized businesses believe that they rely too much on manual and non-automated processing of financial tasks. Therefore, the need for fintech software development services is as high as ever. Let’s see who can become a reliable partner on this path toward business digital transformation.

Minimal project size: $10,000+

Our company has been ranked among the top 50 companies on Upwork. Ronas IT projects include building complex financial systems, such as projects that help users improve their credit ratings, trading app code rebuilds, and development of neobanks compliant with specific regional legal regulations.

The Ronas IT’s development team is proficient in microservice architecture, providing applications with distributed levels of access and high security. We easily perform multiple integrations in banking app development and have an experienced UI/UX design team to create visually appealing and unique user experiences.

We respect our clients’ confidentiality, and therefore, our recent and ongoing fintech projects are under NDA. However, we can briefly share the technologies we implemented in our last project, where we built a neobank for a US company. This case particularly demonstrates our dedication to studying local requirements for financial apps. When developing this application, we followed all necessary regulations, including the SOC 2, PCI DSS, and ISO/IEC 27001 security standards.

To ensure the app's stability and security, we employed a microservice approach. This approach isolates processes, preventing, for example, a transaction service from accessing user data. We created a separate database for each service. To prevent data loss, we implemented replication in Cloud SQL. Other integrations we made for the neobank included KYC verification to prevent fraud from entering the app, Getkard for a cashback system, and Bond for account management and financial operations. We continue to work on the project by adding new features.

Should you be interested in developing a fintech app with our company, we would be happy to help you bring your ideas to life.

What to look for in a fintech software development company in 2024-2025?

Basic principles when choosing a software vendor

Reviews

The best way to learn what to expect from a fintech software development company is to check the experiences of their previous clients. Several platforms support business-to-business reviews that can be trusted. Besides Clutch, mentioned above, other reliable sources include Goodfirms, Upwork, and Designrush. It's crucial to pay attention to whether a client was satisfied with the company's timeliness, work quality, and overall communication.

Experience

If a firm has experience with projects similar to yours, it offers several advantages. First, a development team may have pre-built solutions, which can help your app launch faster. Additionally, you can check if previous clients were satisfied with the results. If the project wasn't under NDA, you can test the application development results. However, if a company lacks relevant experience, they may struggle to handle your project effectively. It's important to see the big picture; even if a vendor has impressive projects or large clients in other industries, they might lack the necessary skills to handle your tasks.

Transparency

This is one of the most important factors. While some argue that transparency is only evident during the work process, it can be visible even before the actual application development process. In the introductory meeting, a manager should clearly outline how often they will share the progress and ensure clients can access the project they are paying for. This includes downloading the code and design files or gaining access to task management systems. Transparency should also extend to the company's pricing policy. For example, at Ronas IT, managers provide clients with two estimates — an approximate one before the project starts and a more refined one after UI/UX design completion and before the application development stage.

Time and quality

Every fintech app owner desires a combination of short development time and a high-quality product. While the delivery time depends on factors like the number and complexity of features, the vendor's timeframe should be transparent and reasonable. Quality is paramount, and to ensure it, developers need to write clear code and follow best practices. At Ronas IT, we worked on projects with poor-quality code written by previous developers, which required complete rewrites instead of just adding features and fixing bugs.

Staff training

When building complex fintech software, a vendor should not only deliver a finished product but also provide documentation and guidance to your staff, especially concerning internal process automation. The resulting project should be easily understood by everyone. This clarity should start with simple UX copywriting and extend to the app's overall logic.

User-centered design

Since fintech apps typically target a large audience, they should be intuitive and user-friendly. This is achieved by following Android and iOS guidelines for building platform-compatible interfaces that are familiar and convenient for users. It's also worth checking the company's UI/UX design team's activity on platforms like Instagram, Dribbble, and Behance. This can give you a glimpse into your future project's design before even contacting the vendor.

Testing

Great coding practices and versatility in automated testing tools have largely replaced the need for manual QA testing. Therefore, developers should be proficient at implementing automated tests and embrace the culture of continuous integration and continuous delivery. Additionally, a modern reliable vendor should use testing protocols like unit tests, integration tests, system tests, and user acceptance tests.

Post-launch maintenance and support

A good fintech software development company should offer its clients continued support after launch. Usually, work doesn't stop at releasing a product to the stores, it's a perpetual cycle of improvements, implementing new features, and other procedures enhancing an app and making it more appealing to clients.

Things to consider when choosing a fintech software development company

While the criteria for good development are similar across industries, there are some specific requirements crucial for fintech software development. The field has its own vulnerabilities, such as dealing with sensitive data, requiring special attention to security measures.

Microservice architecture

Financial software often has isolated processes, meaning they don’t depend on each other. This approach enhances project security by restricting access to user data for services that don't require it. Microservice architecture also helps in fintech software risk management as if one service fails, others will still function.

Security measures

Creating financial software necessitates various methods for protecting user data, from secure coding practices to user authentication. The app's security should include biometrics, multi-factor authentication, data encryption, fraud detection systems, automatic logout, and more. The coding team, during the app's engineering process, should use standards-compliant servers, secure CI/CD pipelines, and reliable frameworks with built-in security features.

Integration capabilities

The vendor should be able to work with Open Banking standards and APIs to ensure the interoperability of different banking systems and third-party apps. Another essential expertise is the ability to integrate with various payment gateways, offering users multiple payment options, such as SWIFT, ACH, and blockchain-based payments.

Regulatory compliance

Financial services onboarding should provide users with Know Your Customer (KYC) and Anti-Money Laundering (AML) checks. KYC/AML is a system for verifying new users through checking their ID and SSN and preventing fraudsters from accessing the app. There are also multiple financial regulations that the software should be compatible with. These include the Payment Services Directive (PSD2), Markets in Financial Instruments Directive (MiFID II), and data protection laws like GDPR in the EU and GLBA in the US. Additionally, each country has its own financial regulations. For example, developers in the US will also follow SOC 2, PCI DSS, and ISO/IEC 27001 standards — all dealing with information security.

Summing up

The modern market offers a wide range of fintech software development companies. We encourage you to use the checklist provided above to ensure the vendor you choose meets the basic requirements of a custom software development company and the specific criteria of a reliable financial software development company. Don't hesitate to read reviews from clients in the financial industry and examine the company's case studies, which they typically share on their websites.

We have extensive experience working with startups to build complex financial software for banks.
