Advanced Features That Set You Apart

Licensing Routes for a Neobank

In India, neobanks partner with licensed banks because RBI does not license neobanks as a separate category; in the US most fintechs work with sponsor banks; in the UK and EU many start under an EMI licence or partner.

Route	What it means	Time to launch	Best for
Banking-as-a-Service (BaaS) partner	A licensed bank or e-money institution holds funds and issues accounts and cards; you build the app and brand	4–9 months	Most startups and brands
E-money or payment institution licence	You hold an EMI or similar licence (UK FCA, EU national regulators) for wallets, cards and payments, but cannot lend deposits	9–18 months for approval	Scale-ups focused on payments and FX
Full banking licence	You take deposits and lend under full bank regulation and capital rules	2+ years and significant capital	Well-funded challengers and incumbent banks
Partnership with an existing bank	Launch a digital brand on a bank's licence and core systems	6–12 months	Banks and NBFCs launching digital brands

Building a Digital Bank App Like Revolut: FAQs

How much does it cost to build an app like Revolut?

A neobank MVP on a BaaS partner typically costs $80,000–$150,000, a full Revolut-style app $150,000–$350,000 and a multi-country super-app $350,000–$1,000,000 or more, plus partner, licence and compliance costs.

How long does it take to build a digital bank app?

About 5–7 months for an MVP with a BaaS partner and 7–12 months for a full app. Getting your own e-money or banking licence can take 9 months to several years.

Do I need a banking licence to launch a neobank?

No. Most neobanks launch through a banking-as-a-service partner or partner bank that holds the licence and customer funds. You can apply for your own licence later as you scale.

What features does a Revolut-like app need?

Digital KYC onboarding, accounts, virtual and physical cards, transfers, multi-currency balances and FX, savings and budgeting, notifications, card controls, support and a compliance back office.

What is banking-as-a-service (BaaS)?

BaaS lets a licensed bank or e-money institution provide accounts, cards and payment rails through APIs, so a fintech can offer banking products under its own brand without its own licence.

Which core banking system should I use?

Options include Thought Machine, Mambu, 10x and Temenos, or the core provided by your BaaS partner. Some neobanks build their own ledger as they scale.

How do neobanks prevent fraud?

With KYC checks, device binding, biometrics, real-time card rules, transaction monitoring, behavioural analytics and fast card freezing and alerts.

Can I add stocks and crypto to the app?

Yes, through licensed brokerage and crypto partners, subject to the regulations in each country.

How do digital banks make money?

Through card interchange, subscription plans, FX and transfer fees, interest income, wealth and crypto fees, lending and business accounts.

Can you build a neobank for India?

Yes. Indian neobanks partner with RBI-licensed banks and integrate UPI, cards, Account Aggregator and KYC services such as Aadhaar-based eKYC and video KYC where permitted.

Is a Revolut clone script a good idea?

Clone scripts can show a demo, but real neobanks need licensed partners, secure ledgers, compliance and scalable architecture, so most production apps are built custom on partner platforms.

Who owns the app and the code?

You do. Source code, designs and documentation are assigned to you; partner platforms remain under their own licences.
