Trusted By Fintech Leaders Worldwide

Our company is trusted by the leading fintech leaders worldwide. These people have trusted us with their resources, and we proved them right. Here is the list of top leaders:

The Neobank Opportunity Is Real, and It Is Growing Fast

As digital banking adoption continues to surge worldwide, businesses have a unique opportunity to disrupt traditional banking models. Nimble AppGenie delivers cutting-edge neobank apps with advanced features, robust security, and seamless user experiences.

The global neobanking market was valued at around $210 billion in 2025, according to Fortune Business Insights. It is projected to cross $310 billion in 2026, growing at a CAGR of roughly 47% through 2030.

Over 500 million customers across 80+ countries now use some form of digital-only banking. That number is expected to reach 350 million unique neobank users by the end of 2026.

More than 300 net US bank branches closed in 2025 alone, according to U.S. News. Consumers, especially those under 40, are done with branch banking. They want instant account opening, real-time notifications, no hidden fees, and mobile-first experiences.

That creates a real business opportunity. Whether you are a fintech startup, an SME looking to launch a business banking product, or a traditional bank that needs to go digital, the time to build a neobank app is now.

The challenge is getting compliance right, execution, choosing the correct tech stack, execution, staying within budget, and hitting a realistic MVP timeline. Most clients struggle with these parts. That's exactly where Nimble AppGenie comes in.

The Neobank Opportunity Is Real and It Is Growing Fast

Our Neobank App Development Services

We understand there's no one-size-fits-all product. Every neobank is different. We offer neobank app development services suiting your business model, regulatory environment, and target audience to build the right solution.

Custom Neobank App Development

We build neobank apps from scratch, tailored to your product vision. Our custom neobank development services ensure every flow, feature, and integration is crafted specifically for your business model. You get complete IP ownership and source code access.

White-Label Neobank App Development

Need to launch faster without building from scratch? We build a white label neobank solution for SMEs, a fully configurable banking platform. You can customize UI, add your branding, and go live in weeks instead of months with lower upfront expenses.

Neobank MVP Development

Not sure if the market wants your product? Neobank MVP development services help launch a lean, working MVP first. You define the key feature set, build it fast, and test with real users, reducing upfront investment.

Neobank for SMEs & Business Banking

Business banking is underserved. Most neobanks target consumers. Our neobank app development for fintech startups helps build B2B neobank apps for SMBs with invoicing, multi-user access, business-grade spending controls, and payroll integrations. This is a market with lower saturation and strong demand.

Consumer Neobank App Development

We create consumer-facing neobanks with the features users actually expect, like virtual and physical card management, savings vaults, BNPL, instant account opening, real-time payments, and budgeting tools. Consumer neobank apps are designed for mobile-first users with zero tolerance for friction.

Neobank API & Third-Party Integration

Modern neobanks run on integrations. Our team connects your neobank app to BaaS providers, payment rails (Visa, Mastercard, SWIFT), KYC/AML platforms, open banking APIs (PSD2), and core banking systems. We know which integrations are easy and which need extra attention.

Neobank App Modernisation & Migration

Running legacy banking software that is slowing you down? We migrate and modernize existing banking platforms to a cloud-native, API-first architecture. You witness lower operational costs, better security, and the ability to ship new features without disturbing what already works.

Neobank Compliance & Security Consulting

Compliance is the most common place where neobank projects go wrong. We provide technical compliance consulting for PCI-DSS compliant neobank app development, covering GDPR compliance, KYC/AML workflows, PCI-DSS architecture, and regulatory readiness for your target market.

Understand Development Cost

Here’s a guide for you to better understand dev cost.

Core Features We Build Into Every Neobank App

Our neobank app development services include prioritizing a core set of features to ensure compliant, secure, and frictionless digital banking. Below are the features we build, what users see, and what runs behind the scenes.

Digital Onboarding & eKYC

Help users sign up in under 5 minutes. We integrate automated identity verification, liveness checks, document scanning (OCR), and regulatory KYC workflows to ensure user onboarding is compliant, fast, and friction-free.

Virtual & Physical Card Management

Instant virtual card issuance for online payments, with the option to request a physical card. Users can control spending limits, freeze/unfreeze cards, and manage merchant blocks, all in-app.

Real-Time Payments & Transfers

We integrate domestic and international payment rails, ACH, SEPA, SWIFT, and Faster Payments so users can send and receive money instantly. Real-time push notifications keep them updated on every transaction.

Multi-Currency Accounts

Users can hold, convert, and spend in multiple currencies from a single account. We build in live FX rates and low-fee currency conversion for freelancers, travel users, and SMEs with global operations.

Savings Vaults & Goals

Users round up spare change, set savings goals, or automate recurring deposits into dedicated vaults using this feature. This drives engagement and increases the average user's product usage.

Spend Analytics & Budgeting

Users can perform automatic transaction categorization, monthly spending breakdowns, and budget-setting tools using this feature. They see where their money goes without having to do anything manually.

BNPL & Credit Features

Buy Now Pay Later (BNPL) and in-app credit products are high-revenue features. We build BNPL flows with eligibility checks, flexible repayment options, and a regulatory-compliant credit agreement presentation.

In-App Customer Support (AI Chatbot)

An AI-powered chatbot helps users with routine queries, card freezes, balance checks, and transaction disputes without routing users to a human agent. Escalation to live support is available for complex issues.

Core Banking System (CBS) Integration

We integrate your neobank app with CBS, connecting leading CBS providers and helping you architect a core banking layer that handles accounts, ledgers, and transaction processing at scale.

Open Banking API Support (PSD2 / REST)

Witness a full open banking API implementation. Third-party apps can securely connect to your neobank, enabling payment initiation, account aggregation, and secure data sharing under PSD2 and equivalent regulations.

Biometric & Multi-Factor Authentication

Face ID, fingerprint login, and MFA are standard. We also implement adaptive authentication that applies stronger checks only when risk signals are detected, keeping the experience smooth for genuine users.

Role-Based Admin Dashboard

A web-based admin panel for your operations team manages users, monitors transactions, handles disputes, runs compliance reports, and configures product features without touching the codebase.

AML / Fraud Detection Engine

Rules-based and machine-learning fraud detection engine monitors transactions in real time. It holds flagged transactions for review or automatically declines based on configurable risk thresholds.

PCI-DSS Compliant Architecture

Every app we build is architected for PCI-DSS compliance. This covers data encryption, tokenization, access controls, and audit logging, which is non-negotiable for any app that handles card data.

Cloud-Native Scalable Infrastructure

We build on AWS, Azure and Google Cloud with auto-scaling, load balancing, and microservices architecture. Your app can handle 1,000 users on day one and 1,000,000 users two years later without requiring a rebuild.

Real-Time Transaction Ledger

A double-entry ledger system that keeps every account balance accurate in real time, even under high transaction volumes. This is the financial backbone of your neobank.

Types of Neobank Solutions We Build

Not every neobank serves the same user, and we totally understand this. Our team of experts builds seven types of neobank solutions. Here's what they are and who can use them.

B2C Consumer Neobanks

These apps are built for everyday consumers that focus on mobile UX, real-time payments, instant onboarding, personalized financial tools, and savings. Think Revolut, Chime, or Monzo, but build for your brand and market.

B2B Business Neobanks

We design digital banking products for SMBs with multi-user access, expense tracking, business card management, payroll, and invoicing integrations. This is a fast-growing segment with a few dominant players in the market.

Challenger Banks

A challenger bank operates with a full or partial banking license and competes directly with traditional banks. We help you build the tech stack and brief on the product model to compete in this space.

Embedded Finance / BaaS Neobanks

Banking-as-a-Service allows non-banks to embed financial products in their apps. Our team builds BaaS-powered neobanks that allow your platform to offer cards, bank accounts, and payments without holding a banking license.

Crypto-Enabled Neobanks

We build crypto-enabled neobanks that support both fiat and crypto. Users buy, spend, and hold digital assets alongside traditional currencies. We integrate exchange APIs, crypto wallets, and DeFi features into a compliant neobank architecture.

Kids & Teen Neobanks

We develop kids & teen neobanks with parental controls, saving goals, spending limits, and other financial education features for under-18 users. It shows robust retention play as users stay when they turn adult.

Travel & Forex Neobanks

The travel and forex neobanks we build offer no-fee international spending, multi-currency accounts, travel insurance integrations, and live exchange rates. These products are ideal for digital nomads, frequent travellers, and cross-border workers.

Our Neobank Development Process

By following a proven framework, we help clients know how to build a neobank app from scratch and launch it with maximum growth and minimal risk. We ensure every step is documented and tracked.

Discovery & Requirement Analysis

We start with your target audience, business model, and compliance requirements. We define the regulatory path, map out the complete feature set, and produce a detailed scope document. This step prevents costly surprises later.

UI/UX Design

Our UI/UX designers build wireframes and high-fidelity prototypes for your user flows - onboarding, payments, dashboards, and cards. You review and approve, then we start writing the code. Good UX saves weeks of rework during development.

Architecture & Tech Stack Selection

We choose the cloud infrastructure, define the backend architecture, document the security model, and select third-party integrations (KYC, BaaS, and payment rails). Here, compliance is designed in, not bolted on.

Agile Development

Development runs in two-week sprints where you see working features every two weeks, not a six-month black box. Weekly status calls keep you updated on blockers, progress, and budget.

QA, Security Testing & Compliance Audit

We run load testing, functional testing, a compliance audit, and penetration testing before release. For PCI-DSS, this includes a formal review of all cardholder data flows. We move ahead after completing this step.

Deployment & Launch

We deploy to production, set up alerts, configure monitoring, and support the go-live. We also handle Google Play and App Store submissions, which have particular requirements for financial apps.

Post-Launch Maintenance & Support

Our work doesn't stop at launch. We offer ongoing support plans that cover performance monitoring, bug fixes, regulatory updates, new feature development, and security patches as your product grows.

Common Question:

Can I build a neobank without a banking licence?" Yes, in many markets. BaaS partnerships with licensed institutions allow you to launch banking products without holding your own licence. We advise on this approach and build the technical layer on top of your BaaS.

Who We Build Neobank Apps For

Our neobank app development services are created for a specific kind of client, one who is serious about launching a real financial product.

Fintech Startups

You have the product idea, and you need a technical partner who has experience in this. We help you go from ideation to a working, compliant neobank MVP and then to a full product without draining your funds on avoidable mistakes.

Enterprises Adding Embedded Finance

More businesses are embedding financial products into their platforms. If you run an eCommerce platform, B2B marketplace, SaaS platform, or digital marketplace, we can help you build a BaaS-powered neobank product that increases customer retention and creates a new revenue stream.

Traditional Banks Going Digital

Legacy infrastructure is costly to maintain and slow to update. We help traditional banks build digital-first products either as standalone neobank apps or as digital layers on top of existing core banking systems.

Investment-Backed Founders

We understand what investors look for in a fintech product. We help you launch an MVP that shows product-market fit, demonstrates technical credibility, and positions you well for your next funding round.

Common Problems Clients Face and How We Solve Them

Most fintech firms come to us after running into some common yet major problems. Let’s check what they are and how we handle them.

We do not know how to handle compliance and licensing.

This is the most usual blocker for neobank founders. Our team includes compliance consultants who have navigated PCI-DSS architecture, KYC/AML setup, and BaaS licensing structures in various markets. We guide you through the options and create a suitable technical layer. We don't give vague advice, we build compliance checklists and produce architecture documents your legal team and regulators can review.

Our previous development team could not handle banking-grade security.

Standalone app developers usually underestimate what financial-grade security needs. Tokenization, encryption, session management, pen testing, and fraud detection are not optional extras for a neobank. Every project we build goes through penetration testing and security architecture review before launch.

We got a quote, but the real cost was three times higher.

This happens when the initial scope misses critical items - compliance infrastructure, third-party API costs, testing overhead, and card programme fees. We break down the complete cost picture upfront, including operational costs beyond the development fee. There are no surprises in our proposals.

We need a developer who understands the business side, not just the code.

We assign a dedicated project manager and a technical lead to every engagement. They understand your business objectives and translate them into technical decisions. You partner with a neobank app development company that pushes back when a feature is unnecessary or when there is a better approach, not just a team that executes whatever is written in the requirements document.

We want to launch fast without waiting 18 months.

A full-fledged neobank takes 6-12 months to create. But you don't need every feature on day one. Our MVP approach gets a working product in front of users in 12-16 weeks. You validate the model, accumulate user feedback, and prioritize what to build next based on real data, not assumptions.

Frequently Asked Questions

Here are the common frequently asked questions that will help you to solve your common questions related to connecting with us and building a crypto wallet app:

Neobank development cost depends on the scope. A lean MVP with core features, accounts, onboarding, virtual cards, and basic payments, customization typically costs $30,000 to $80,000. A full-featured neobank with multi-currency support, lending, savings, and compliance architecture runs $150,000 to $300,000+. We provide a detailed breakdown in every proposal, including third-party API costs, compliance setup, and infrastructure, not just the development fee.

An MVP takes 12 to 16 weeks. A mid-range neobank with standard features takes 4 to 8 months. A full-featured product with advanced compliance and integrations takes 8 to 14 months. Timeline is driven by feature count, complexity of integrations, and the regulatory requirements of your target market.

Not always. In many markets, you can launch a neobank by partnering with a licensed BaaS provider that holds the banking licence on your behalf. You build the product on top of their infrastructure. We advise on the right licensing path for your target market and build the technical layer that connects to your BaaS partner.

A white-label neobank is a pre-built banking platform that you brand and configure to your needs. It is faster and cheaper to launch than a fully custom build. We offer white-label solutions for clients who need to go to market quickly, typically deployed and ready for branding in 4 to 8 weeks.

KYC/AML workflows, PCI-DSS compliant architecture if you handle card data, and compliance with the financial regulations in each market you operate in. For US-based neobanks, this includes FinCEN/BSA requirements. For Europe, PSD2 and GDPR. For the UAE, CBUAE, and potentially DFSA. We cover all of these and advise on what is required for your specific product and market.

We offer structured support plans that cover bug fixes, security patches, performance monitoring, compliance updates (regulations change), and new feature development. The plan is agreed upon before launch, so you know exactly what is covered and what the ongoing cost is.

A neobank typically operates by partnering with a licensed bank or BaaS provider, and it offers banking features without holding its own banking licence. A challenger bank holds its own banking licence (full or partial) and operates as a regulated bank. The terms are often used interchangeably, but regulators treat them differently. We have built products for both models.

Common revenue streams include interchange fees (a percentage of every card transaction), subscription plans (premium accounts), lending and BNPL interest, currency conversion fees, and API/BaaS fees for white-label partners. The most successful neobanks combine multiple revenue streams rather than relying on a single source.
