What is a Neobank and Digital Bank?

Neobank and digital bank are terms frequently used in today’s financial world, but what exactly do they mean? What is digital banking, and how different is it from the neobank definition?

Neobank

A neobank, often called a digital or challenger bank, is a financial institution that operates exclusively online, without any physical branches.

Neobanks offer a wide array of banking services, including savings accounts, checking accounts, payment processing, lending, and other financial products — all accessible ONLY through web and mobile applications. Neobank meaning for fintech industry development is difficult to overestimate.

Here’re some examples of top neobanks as of 2025 and their strengths in short:

• Revolut. All-in-one platform for banking, investing, crypto, and budgeting with global currency exchange.
• N26. Sleek, mobile-first bank with strong EU coverage and intelligent budgeting tools.
• Chime. Fee-free US banking with early direct deposit, credit builder, and automatic savings.
• Monzo. Transparent and intuitive banking experience with smart spending insights and savings pots.
• Starling Bank. Profitable UK neobank with top-tier customer service and powerful tools for SMEs.
• NuBank. Latin America’s digital banking giant offering accessible credit and user-first design.
• Zolve. Cross-border banking for immigrants with instant US accounts and credit-building options.
• Current. US neobank targeting Gen Z with cashback rewards, instant transfers, and high-yield savings.

Digital Bank

A digital bank is essentially a traditional bank that has transitioned its services into digital.

Digital banks provide the same core banking services as brick-and-mortar institutions but primarily through online channels like websites and mobile apps. Digital banks may still maintain physical branches, but they emphasize offering convenient digital access to banking services.

Differences 

The distinction between neobanks and digital banks lies in their origin and approach:

• Neobanks are born in the digital age without legacy systems or physical branches. 
• Digital banks are traditional banks that have adapted to the digital landscape.

While both aim to provide online banking services, a neobank takes this concept a step further. It’s not just about transferring traditional banking services to digital channels; it involves the development of something entirely new and advanced in the world of finance. 

Suppose you’re wondering how to create a neobank or looking to start a digital bank. In that case, you should understand that neobanks provide a more innovative approach since they are made from the bottom rather than on the base of traditional banking institutions.

• A notification and reminder system. It must inform customers about account activity, payment receipts, and app updates.

You need to add some cutting-edge features to build a neobank that stands out from the rest. Even one or two may put your digital bank on the frontline. We’ve put together the list for your neobank app development:

• Cashback. This is basically a return of a small percentage of the amount of customer’s purchases. Typically, cashback percentages vary across product categories.
• The changeable CVV2. Such a functionality keeps balances safe if a customer loses their phone.
• Cost tracking. It shows users where their money goes (e.g., food, home, study, etc.).
• The referral system. This collaboration and monetization model allows users to get rewards if they engage their family, friends, coworkers, and other people they know in the bank.
• The accumulating system. It helps to collect money for specific goals. An amount of money is automatically taken out of a checking or savings account as a rest.
• Stocks. This feature allows users to buy and sell stocks.
• Cryptocurrencies. Support for cryptocurrencies allows to store, send, and receive digital currencies like Bitcoin and Ethereum directly within the app.
• Budgeting. Budgeting assistant helps clients get their bills, groceries, and entertainment in line by letting them set a budget for how much they want to spend on each.

How To Build a Digital Bank or Neobank from Scratch? 

As a fintech professional and CEO of a fintech company with over 13 years of experience and real-life knowledge developing a neobank from scratch in 9 months, I’m delighted to share practical insights on creating such a product since I already have the expertise you may need.

If you are wondering how to start a digital bank, this information will be useful for you as well. The next section will delve into the critical steps, complete with practical examples and advice.

Starting neobank app development from scratch is a journey filled with challenges and rewards. Remember to stay true to your vision, prioritize compliance and security, and deliver a seamless user experience. Neo banking is all about adaptability and innovation, and by following these steps, you’re on your way to making a significant impact in the financial industry.

Step 1. Define Your Vision and Mission

Step one in how to start a neobank is defining a clear vision and mission. Take inspiration from real-life success stories of fintech companies like Monzo, a UK-based neobank that aimed to make banking simple and accessible. Define your unique selling proposition (USP) and identify the problems your neobank will solve for customers. For instance, if you’re targeting millennials, create a bank that prioritizes features that enhance budgeting and offer real-time insights into spending.

To-do list:

1. Take inspiration from real-life success stories.
2. Define a unique selling proposition (USP).
3. Identity problems your product will solve.
4. Prioritize and customize features for user needs.

Step 2. Understand Regulatory Compliance

To launch a digital bank, neobank, or fintech solution, securing the right license is paramount. However, the landscape has shifted. In the past, only a full banking license would suffice. Today, you can operate a bank-like service with an EMI (Electronic Money Institution) or PI (Payment Institution) license.

These licenses allow you to offer many banking services, except granting loans and accepting deposits. Notably, Revolut, a prominent fintech player, hasn’t pursued a banking license in the US — a testament to the evolving norms. So, what’s the difference between EMI and PI licenses?

An EMI is an institution that’s authorized to issue electronic money.

Holding an EMI license allows you to:

• Issue and distribute electronic currency, enabling customers to store funds in an e-wallet for payments.
• Execute currency exchanges.
• Facilitate direct debit or credit transfers.
• Transfer funds to other customers.
• Handle withdrawals and deposits.
• Grant customers access to their account details.

On the other hand, PI stands for “Payment Institution.” A Payment Institution is a type of financial entity that is authorized to provide certain payment services without issuing electronic money. To understand well how to start a neobank you need to be well-versed with EMI and PI concepts.

By obtaining a PI license, you:

• Can’t issue electronic money.
• Can’t facilitate payment transactions (e.g., transfers).
• Can’t store money long-term.

In short, EMI = e-money + payments. PI = just payments.

There are distinct things EMI and PI cannot provide:

• Traditional bank accounts (only e-wallets are permissible).
• Deposit guarantees.
• Conduct international transactions.

Such services typically necessitate a banking license, which is more challenging to secure.

In essence, while a full banking license might be the traditional route, the EMI and PI licenses are viable alternatives for those looking to break into the fintech space without diving deep into traditional banking regulations.

To-do list:

1. Start by researching the specific compliance requirements in your region.
2. Seek legal and expert guidance.

Step 3. Assemble Your Dream Team

Neobank app development requires diverse expertise. Look for experts who understand fintech, such as former employees from established fintech firms or banks. Collaboration is key in this process, and an agile mindset is essential to adapt to unforeseen challenges. Consider hiring experienced professionals who have faced and conquered hurdles in fintech.

To-do list:

• Seek fintech experts with real experience (pay attention to projects they built — was it neobanks mobile app development or web development, which technologies they worked with, which integrations they set up).
• Prioritize collaboration and agile thinking.
• Hire professionals with a track record of overcoming fintech challenges.

Step 4. Focus on User Experience and Marketing

User experience (UX) can make or break your neobank. Take inspiration from Chime, a US-based neobank with a user-friendly mobile app. Ensure your digital channels are intuitive, secure, and accessible. Regarding marketing, remember the story of one of our customers — Pi-1, an award-winning BaaS platform from the UK. Their product wasn’t significantly different from others, but their success was driven by effective marketing, a modern-looking app, and excellent features, targeting banks and fintechs.

Establishing your brand’s look can achieve better market results and capture a larger market share. Effective communication of your brand’s unique value proposition can set you apart, even in a competitive landscape.

To-do list:

1. Prioritize intuitive, secure, and accessible digital channels.
2. Invest in user-friendly mobile app design.
3. Emphasize effective communication of your unique value proposition in marketing.

Step 5. Prioritize Compliance and Security

Don’t underestimate the importance of compliance and security for neobank app development. A great example is Monese, a UK neobank, which learned this hard when facing regulatory challenges. The company’s initial difficulties might have arisen from insufficient Know Your Customer (KYC) and AML procedures. 

Compliance involves adhering to various financial regulations and ensuring your neobank operates within legal boundaries. One critical aspect is KYC, which consists of verifying your customers’ identities to prevent fraud and financial crimes. Anti-Money Laundering (AML) processes are designed to detect and report suspicious activities that might indicate money laundering or other illicit financial transactions.

It would be best to stay updated on regulations like GDPR (General Data Protection Regulation) in Europe, which also governs the handling of personal data. Security is paramount in protecting customer data from threats, cyberattacks, and breaches. Consider partnering with cybersecurity experts who can help you implement robust security measures, encryption protocols, and monitoring systems to safeguard customer data and maintain compliance with industry standards.

Tip:

Although numerous security tools and measures are at your disposal, remember that they should be okay with your app users. Ideally, when it comes to how to start a neobank, security should work behind the scenes, ensuring a seamless and user-friendly experience, such as using video calls for identity verification or entering the last symbols of phone number calling.

To-do list:

1. Prioritize compliance with financial regulations, including KYC and AML processes.
2. Stay informed about data protection regulations like GDPR.
3. Invest in robust cybersecurity measures to protect customer data from potential threats.

Step 6. Develop Your Business Processes

Start with robust business processes before diving into software development. Document how customers will onboard, how transactions will be processed, and how compliance procedures will be handled. This approach streamlines software development and ensures your operations run smoothly.

To-do list:

1. Craft a seamless onboarding process to ensure customers can easily open accounts and use your services. 
2. Define efficient workflows for processing transactions to guarantee your digital channels are intuitive, secure, and accessible.
3. Prioritize KYC and AML processes to prevent regulatory challenges.
4. Create a secure data management system to handle customer information (use tools like Looker, Tableau, or Power BI). 

Step 7. Choose the Right Software Engineering Approach

Engage engineers with fintech experience as they understand the intricacies. Ensure your engineering team can make informed choices and select technologies tailored to the neobanking environment. Without this expertise, engineers may inadvertently choose data types or technologies that could result in balance inconsistencies.

Choosing the right technologies tailored to the neobanking landscape is a basement for a successful product, the same as a base for the future house.

How Do Neobanks Make Money?

There are many business models in fintech, and we’ve already described some of the most popular nowadays. Among them, there are a few specifically spread from which neobanks make money.

#1 Interchange fee. A significant portion of a neobank’s revenue comes from the interchange fees paid by merchants when users use their debit cards to make purchases. Every time a Visa or Mastercard debit card is used to make a purchase, Visa adds a percentage fee to the total. In return, Visa sends a portion of the fees to a neobank.

#2 Loans and overdrafts. In exchange for a fee on each purchase, they facilitate the use of credit cards. When customers go above their restrictions, they pay interest, which generates revenue for the company.

#3 Additional accounts. Digital banking solutions make money from the interest that tacks on to new account balances is another source of revenue.

#4 Withdrawal fee. Neobanks usually accrue interest on the ATM fees, which is another source of revenue.

#5 VIP client services: Offering premium services for a specific fee is common among neobanks, catering to high-value clients.

How Much Does It Cost to Build a Neobank App?

Building a neobank app is no small feat; it requires careful planning, development, and substantial investment. Here’s a breakdown of the potential costs and considerations involved:

1. Cost of Custom Development

Starting a neobank app from scratch can be a pricey venture. To give you a perspective, consider our experience of building the Pi-1 BaaS solution, which was developed at an estimated cost of $4 million. 

It’s clear from this figure that you won’t be creating such an app for a mere $100,000. The scope and features you desire play a pivotal role in determining the cost, and you should know them if you’re looking to how to start a neobank.

It’s also crucial to understand that development costs fluctuate depending on the region. For example, North American developers might charge between $150 - $250 per hour. Contrast this with Ukrainian developers who may charge as low as $60 - $90 per hour. Given that the development phase can span 9 months to 2 years, these regional rate disparities can have a significant impact on the total expenditure.
