How to Build a Neobank from Scratch in 2024Introduction

Neobanks are on the rise and this trend is going to persist. According to research, by 2025 over 80 million people in the United States will be using neobanks. In 2022-2025 the European market is expected to grow with 53%. The segment’s growth is due to the lack of withdrawal expenses and monthly fees, and low transaction costs.

It’s no surprise more and more tech savvy users around the globe are choosing to make the switch from traditional banks. The emphasis on agility and innovation coupled with excellent customer experience drives users to these FinTech players. Deciding to build a neobank in 2024, hence, seems like a smart decision.

Every such project must start smart, too. Hopefully, you have now identified the unique banking needs of a large enough target audience. The discovery stage is crucial for ensuring your product-market fit. It’s what will help you choose the right business model that suits your business best.

Before you start: set yourself up for success

The regulatory framework operating in the financial industry is strictly designed to protect both consumers and businesses. You must research and evaluate the sets of rules in place in every country of operation. Also, users have a wide range of priorities and you have to be aware of them.

This is how you will increase your chances of building a large enough customer base. Being profitable hinges on persuading people to switch accounts from other financial providers — you have to be fiercely competitive. Choose a highly personalized set of features that prioritize ease and speed.

In this context, we can’t underscore enough the importance of choosing the right technology partner. At Scalefocus, we have helped develop four neobanks from the ground up. We know first-hand what features are in-demand and how to navigate the tech challenges of the end-to-end development process. Our team can find and fix your pain points early on, which is very important.

In this article, we are going to share the fundamentals of building a neobank from scratch in 2024. Let’s dive right in!

Starting your neobank: 7 tips from Scalefocus

1. Choose your tech stack as early on as you can

This piece of advice is important because it will help you avoid redoing features. It’s going to ensure you use your resources the right way instead of wasting them. The finance industry is changing fast, so choose a tech stack that is flexible and scalable. You need to be able to adjust quickly once your product is out.

As your user base grows and you attract more potential customers, you will have to replace some tech ecosystem components and upgrade others. Downtime is another factor to consider. How long will it take for the update of a database or other critical elements of the app? Ultimately, a well-defined tech stack enables a frictionless customer experience.

The Scalefocus tip

Our team knows what options are available on the market, and how to choose a tech stack that will get your company ahead. We strongly recommend selecting the technologies for your mobile neo-banking app right from the MVP phase. Otherwise, you could end up managing multiple codebases and doing unnecessary rework.

Our experts will consider important factors like costs and time when making this decision. Also, review the BaaS provider’s SDKs, APIs, and documentation for quality, availability and security. Using a BaaS provider saves time and money compared to building everything from scratch.

2. Look into different BaaS providers

Banking-as-a-Service (BaaS) platforms provide a framework that includes financial services, payments, compliance and security. These platforms let neobanks open up their APIs for third parties to develop new services. BaaS providers’ APIs enable neobanks’ users to manage their cash flows and loans, make payments, etc.

Thus, FinTechs can focus on creating tailored financial products. Using a BaaS provider saves time and money compared to building everything from scratch.

Considerations when Choosing a Banking as a Service Provider

The Scalefocus tip

Our experts will assist you every step of the way when choosing an off-the-shelf banking infrastructure. First off, we will make sure we clearly define the features and capabilities of your app. This is fundamental for picking the right provider.

Also, it’s worth considering which other financial institutions’ products are already live. Some BaaS providers lack actual implementation capabilities or can perform implementations in other regions or markets.

Next, check the BaaS provider’s SDKs, APIs, and documentation for quality and availability. Their security and performance are the other crucial factors to consider. Their security and performance are the other crucial factors to consider. To evaluate even more accurately ask for live demonstrations in real or sandbox environments.

What we also suggest is thinking about the flexibility and the customization. Ideally, the BaaS provider will allow you to customize and extend its functionality. Checking for restrictions or limitations that could impede your app’s design is also a must.

3. Develop a customer-centric mobile application

Your mobile application is a major part of your product as users want to bank from their mobile devices. It needs to offer everything from onboarding to bank account management options. This must come in a mobile solution that is as user friendly as possible to attract the most tech-savvy customers.

The features you include will vary depending on your value proposition and your customer’s needs. However, in our experience these are some of the most common functionalities that compelling neobanks offer: savings and checking accounts, payments, credit/debit cards, transaction history, budgeting and investing options, notifications, and real-time chat support.

The Scalefocus tip

When it comes to your mobile app, which is the face of your business, we recommend using quick prototyping. This method creates a user experience for customers. It also checks if the UI/UX is best for the intended audience.

Creating features from scratch is better than using external libraries, which could have malware. We have experience creating the core frameworks for both  iOS and Android applications from scratch. If you go for the first option, make sure the third-party code comes from verified vendors and security standards meet the industry standards

4. Ensure compliance and security

When we are talking about compliance in the context of banking, it goes hand in hand with security. This is an opportunity to get a competitive advantage over other players. However, a lot of neobanks are not directly regulated. Instead, the regulated institution is the bank that it’s partnering with.

It can be hard to keep user accounts and data safe if your partner works with untrustworthy third-party providers. That is why choosing a bank with good security practices is crucial.

On the other hand, if you do want to get your full-fledged banking licenses, ‍be aware that regulatory frameworks vary across types of financial services and territories. Your licensing depends on your value proposition, business model and the geographical location you will be operating in.

 Practices for Neo Banking

The Scalefocus tip

In the first case, you will be regulated by the partner bank. The financial institution you chose to work will determine the methods for safeguarding accounts and transactions. However, your BaaS provider will be able to support you in building a great compliance practice because there are details that you will be responsible for.

For example, you need to make sure to include compliance features in your app. They will be how you adhere to regulatory requirements, such as identity verification and fraud detection.

In the second case, you need to select a technology partner who has sufficient experience in certifying a solution with local financial authorities, as well as in obtaining payment processing and data security certifications.

5. Build an infrastructure that supports your business model 

Building a reliable and scalable neobanking app is mostly about having the developers with the relevant FinTech experience. Once you have obtained them and they are onboard, they will select the necessary components.

These components include backend setup, frameworks, and structure. As neobanks operate in a highly data-sensitive environment, they don’t host all services on a public cloud. Instead, most of them opt for hybrid cloud infrastructure.

Neobanks use both public and private clouds for different purposes: public for integrations and private for service development. A cloud environment helps developers create platforms for neobanks to improve customer experiences and provide a better platform.

Neobanks are great for the groups of people who want good customer service, lower fees, convenience, and improved digital experiences. Next, check the BaaS provider’s SDKs, APIs, and documentation for quality and availability.

The Scalefocus tip

Depending on your project’s timeline and budget we will select the best backend tech stack for your product. We will also consider its specifications, such as its type, complexity, size and business goal. The neobanks we have helped develop relied on hybrid-cloud infrastructure as it allows for unmatched resilience and agility.

It provides an agile environment to create, test, deploy and cancel services within short timeframes. We recommend this infrastructure type because it combines the security of an on-premise server with the benefits of public clouds.

Additionally, internal processes should not be left behind. Setting and documenting the procedures and SLAs might seem tedious, but once your neobank is live, it will surely spare you the imminent conundrums when scaling it.

6. Think customer-centricity when it comes to strategy

Strategically speaking, this is not simply a step in your development process. Instead, it’s a 24/7 journey. Innovation is synonymous with neobanking and new players must be aware of that. Growth is crucial in this small and highly saturated market. Start with customer-centricity and build your marketing strategy around it, too.

Also, innovative customer-centric solutions mean venture capitalists will get faster returns on their investment. The more innovation-proof your features are, the bigger the sustainability of your entire neobanking offering. The most reliable way to achieve this is by putting customer needs first  instead of simply using customer-centricity as a buzzword.

The Scalefocus tip

At Scalefocus, we understand customer-centricity better than most technology companies partnering with neobanks. In our experience, FinTech players must focus on four distinct customer needs and build on them.

These are, (1) the need to pay an individual or a company — payments; (2) the need to get funds — credit; (3) the need to grow the funds they already have — investment; (4) the need for insights to improve their finances — financial input. You must center your product around the first 3 needs. The fourth one should use data from them and provide suggestions on how customers can optimally manage their money.

Customer-centric companies were 60% more profitable compared to companies that were not focused on the customer.

7. Turn design into an extension of your excellent product 

If a customer’s banking app makes them reluctant instead of eager to use it, its design is poor. The desired outcome is simplified transactions, not confusion. The next logical question would be if there is a formula for the perfect app design. The short answer is: no.

However, creating a high-quality user experience is not rocket science. The general style of the app is crucial, and it’s composed of all elements, such as fonts, colors, etc. At its core, good UX/UI creates trust and builds confidence in your product.

This method creates a user experience for customers. It also checks if the UI/UX is suitable for the target users. Our experience has shown that simple design is a key feature of neobanking. It’s crucial that you stay up-to-date with trends and find new ways to create interfaces that meet users’ changing needs.

The Scalefocus tip

What we strongly recommend you focus on, apart from minimalism, is personalization. It is the game changer when it comes to building customer loyalty. Based on data analytics and insights, such as transaction history, location and others, designers can create personalized experiences. 

Another aspect of your approach should be ensuring important information is at the user’s fingertips. Additionally, avoid the traditional authentication method, like passwords or one-time codes. Instead, utilize biometric authentication and digital signatures. That is how you will make the onboarding fast and secure.
