Neobank App Development Company

OmiSoft builds custom neobank applications from the ground up — not rebranded white-label modules. Every engagement covers iOS and Android delivery, core banking integrations (Mambu, Marqeta, Galileo), virtual and physical card issuing, IBAN account provisioning, and SEPA/SWIFT/ACH payment rails. Compliance architecture is designed in from day one: PSD2, PCI DSS, KYC/AML risk scoring, and SCA workflows are structural requirements, not post-launch patches.

Neobank Architecture Options: MVP, Full-Scale and White-Label

Architecture choice is not a stylistic preference — it directly determines your compliance scope, regulatory timeline, and total build cost. The three paths below start from materially different conditions and serve different stages of product maturity.

  1. Neobank mvp development option

    Neobank MVP

    A focused product that validates your core proposition without the full compliance surface area of a licensed neobank. Typical scope: one primary account type, one payment rail, basic card issuing, and identity verification. MVP architecture is modular by design — compliance scope expands incrementally as the product progresses through regulatory approval stages and user volume grows. We scope MVP builds to avoid architecture decisions that create expensive refactoring when scaling to full-license requirements. The MVP codebase is the production codebase; there is no throwaway prototype phase.

    • Fintech startups
    • Seed-stage products
    • Compliance testing
    • Pre-license market validation
  2. Full scale neobank platform development

    Full-Scale Neobank Platform

    A production-grade platform built to operate under EMI license or full banking license requirements from day one. Full-scale builds include multi-currency accounts with IBAN provisioning, card issuing, SEPA/SWIFT/ACH rails, the complete KYC/AML compliance stack, fraud detection, back-office tooling, and regulatory reporting. Architecture is designed for 100,000+ active users from launch — not a prototype horizontally scaled under pressure. Regulatory documentation, audit trail design, and data residency requirements are built into the architecture specification before development starts, not documented retroactively to satisfy a licensing query.

    • EMI-licensed businesses
    • Series A+ fintechs
    • Enterprise banking product teams
  3. White label neobank solution option

    White-Label Neobank

    For teams where speed to market outweighs the need for bespoke differentiation, our white-label neobank solution delivers a pre-built, compliance-tested platform customized to your brand and configuration requirements — typically live in 4–8 weeks. Full source code ownership transfers on delivery; this is not a SaaS licensing model. The platform is yours.

    • Teams requiring fast market entry
    • Banks launching digital sub-brands
    • Fintechs piloting a new geography

CHALLENGES WE SOLVE

Neobank App Development Challenges We Solve

Building a neobank means solving problems that don't exist in standard mobile development — regulatory licensing, core banking integrations, fraud architecture, and compliance-grade onboarding. These are the four failure points we see most often, and how we address them.

Regulatory Compliance & Security Risks

Most teams hit EMI license blockers mid-build when KYC/AML logic doesn't align with PSD2 SCA requirements. We map EMI registration pathways, KYC/AML risk program design, and SCA workflow specification before a line of code is written.

Slow & Costly User Onboarding

40–60% drop-off at identity verification is the industry norm without biometric liveness detection. We integrate SumSub, Onfido, or Persona with parallel risk scoring — targeting sub-3-minute onboarding that clears regulator-grade requirements without hurting conversion.

Core Banking Integration Complexity

Mambu, Marqeta, and Galileo look simple from the API docs. Ledger reconciliation, idempotency handling, and transaction state management under failure conditions expose gaps that cost months. We carry production integration experience with all three platforms.

Scalability Under Transaction Load

Payroll cycles and settlement windows expose monolithic architectures. We build neobank backends as Kubernetes-orchestrated microservices with event-driven transaction processing — auto-scaled from day one, not retrofitted when load becomes a problem.

Architecture & Tech

Our Neobank App Development Services

OmiSoft delivers full-cycle neobank app development — from EMI license strategy and architecture design through to App Store submission and post-launch support. There are no mid-project handoffs between agencies or contractors; the same engineering team that scopes your compliance architecture ships your production application.

Contact Us
  1. Neobank Discovery & Compliance Strategy

    We map your target market's licensing requirements — EMI registration, PSD2, EU AML directives, US MSB — and cross-reference them against your feature roadmap to surface compliance blockers before they reach the build phase. Output: a compliance specification, feature prioritization matrix, and architecture brief ready for development kickoff. Runs 2–4 weeks.

  2. Core Neobank App Development

    React Native (TypeScript) for iOS and Android from a single codebase. Core scope: multi-currency accounts, virtual and physical card issuing, IBAN provisioning, SEPA/SWIFT/ACH rails, and real-time transaction processing via event-driven architecture. Direct BaaS integration with Mambu, Marqeta, or Galileo. App Store and Google Play submission included.

  3. KYC/AML & Compliance Integration

    We integrate SumSub, Onfido, or Persona: biometric liveness, multi-document OCR, PEP/sanctions screening, and automated risk tier assignment at onboarding. SCA flows are built to PSD2 specification with fallback challenge mechanisms. GDPR data handling — consent management, data minimization, right-to-erasure — is structural, not bolted on post-launch.

  4. Core Banking & BaaS Integration

    Production integration experience with Mambu, Marqeta, Galileo, Stripe Connect, Plaid, and Wise — ledger reconciliation, idempotency management, and webhook reliability included. For clients with existing core banking infrastructure, we design and run BaaS migration paths with a parallel-run phase to validate reconciliation accuracy before cutover.

  5. Admin Panel & Back-Office Tools

    Real-time transaction monitoring dashboards, configurable fraud detection rule engine, role-based user management, and automated SAR/CTR reporting — built alongside the customer-facing app. Fraud rule thresholds update through the back-office interface with full audit logging; no code deployment required.

  6. Crypto-Friendly Banking

    Hybrid fiat/crypto account architecture: fiat accounts and IBAN alongside stablecoin balance tracking, USDC settlement rails, and cross-border routing via stablecoin intermediaries. Crypto features operate under the same KYC/AML compliance framework as fiat — no compliance gap. Architecture absorbs regulatory reclassification of crypto assets without requiring a platform rebuild.

TECH STACK & INTEGRATIONS

Neobank Technology Stack and Banking Integrations

Enterprise architects evaluate development partners by the stability and depth of their production stack — the choices below are deliberate selections validated in production fintech environments, not default framework preferences.

Mobile Frontend

React Native (TypeScript) delivers iOS and Android from a single codebase without performance compromises at the transaction UI layer. Swift and Kotlin cover platform-native requirements: secure enclave operations, push provisioning for Apple Pay and Google Pay, and biometric hardware access.

  • React Native
  • Flutter
  • Swift
  • Kotlin

Backend & APIs

NestJS handles the financial services backend where transaction processing, compliance event emission, and webhook ingestion run within the same service boundary. Go covers latency-critical payment routing. Python runs fraud scoring pipelines and batch reporting jobs.

  • Go
  • Python
  • Node.js

Databases

PostgreSQL is the primary transactional store — ACID compliance is non-negotiable for ledger operations where double-spend protection and reconciliation accuracy are regulatory requirements. Redis handles session state and real-time balance caches. DynamoDB covers high-throughput audit trail event logs.

  • PostgreSQL
  • Redis
  • Amazon DynamoDB

Banking & BaaS

Production integration experience — not first-time API explorations scoped into your timeline. Mambu provides the core banking ledger; Marqeta and Galileo handle card issuance; Plaid covers open banking connectivity; Wise manages international payout rails.

  • Mambu
  • Marqeta
  • Galileo
  • Stripe Connect
  • Plaid
  • Wise

KYC/AML

Each platform has different document coverage depth, pricing model, and jurisdictional strength. Platform selection is made during the Discovery phase based on your target geography, expected monthly verification volume, and the risk tiers your compliance program requires. We have production implementations of all three.

  • SumSub
  • Onfido
  • Persona

Cloud & DevOps

Infrastructure that scales predictably, audits every change, and carries the compliance certifications partner banks and regulators expect. Kubernetes manages container orchestration with auto-scaling calibrated to transaction volume patterns, not generic CPU thresholds. Infrastructure changes are peer-reviewed and reversible via Terraform.

  • AWS / GCP
  • Kubernetes
  • Docker
  • Terraform

WHY OMISOFT

FAQ

Frequently asked questions

What is the best neobank app development company for a custom build?

The right partner depends on whether you need a company with experience in compliance architecture (not just mobile development), production integrations with BaaS platforms like Mambu, Marqeta, and Galileo, and a track record of delivering to financial services regulatory standards. OmiSoft has built production crypto payment applications, multi-currency wallets, and DeFi platforms — the same architecture constraints that apply to neobank development. We handle compliance mapping, core banking integration, KYC/AML implementation, and App Store submission as a single delivery team, not as coordinated sub-contractors.

How long does it take to build a neobank app from scratch?

Build timelines range from 3–6 months for a focused MVP — single currency, one payment rail, KYC integration — to 6–12 months for a full-scale platform with multi-rail payments, card issuing, fraud detection, and complete compliance infrastructure. Timeline is primarily driven by integration complexity and the number of regulatory jurisdictions the product must serve simultaneously. Discovery and compliance mapping, which run before development begins, add 2–4 weeks but prevent the 3–6 month delays that compliance blockers cause when they surface in the middle of a development sprint.

How much does neobank app development cost?

MVP builds typically start from $40,000. Full-scale neobank platforms start from $120,000. Enterprise and white-label configurations are priced individually based on compliance scope, integration count, and target delivery timeline. The largest cost driver is not development hours — it is integration complexity. A platform requiring Mambu, Marqeta, SumSub, and direct bank API connections costs materially more than a single BaaS provider integration. We scope all projects in detail before pricing and provide fixed-scope estimates rather than open-ended time-and-materials contracts.

Can you help with EMI license or banking compliance requirements?

We provide compliance architecture specification, regulatory documentation for technical requirements, and audit-ready system design that satisfies the technical components regulators evaluate. We are a software engineering firm — we do not submit EMI license applications on your behalf. What we deliver is the technical evidence package: KYC/AML program implementation documentation, PSD2 SCA flow specifications, PCI DSS scope reduction through tokenization, SAR/CTR-ready reporting infrastructure, and security test reports. We have worked alongside clients' regulatory counsel through licensing processes and understand which technical artifacts regulators require at each stage.

What is the difference between custom neobank development and a white-label solution?

Custom development produces a proprietary codebase built to your exact specification — feature set, compliance scope, integration stack, and user experience are defined by your product requirements, not the limits of a pre-built platform. White-label delivers a compliance-tested platform customized to your brand and configuration requirements, typically going live in 4–8 weeks. Both options transfer full source code ownership on completion — OmiSoft does not retain licensing rights to either. Custom development is the right choice when your product requires differentiation a configurable platform cannot deliver. White-label is right when speed to market outweighs the need for bespoke features. Both paths are offered by OmiSoft.

Which core banking and BaaS systems do you integrate with?

Active production integration experience covers Mambu (core banking ledger), Marqeta and Galileo (card issuing and BaaS processing), Stripe Connect (payment processing and marketplace infrastructure), Plaid (open banking connectivity, account aggregation, and income verification), and Wise (international payment rails and multi-currency accounts). We also build direct bank API integrations to PSD2 and Open Banking UK technical standards for payment initiation and account information access. BaaS platform selection is made during the Discovery phase based on your target geography, card program structure, and the licensing model you are operating under.

How do you handle KYC/AML compliance in a neobank application?

KYC and AML are integrated at the architecture level, not added as a standalone vendor widget. We implement automated identity verification through SumSub, Onfido, or Persona: biometric liveness detection, multi-document OCR, automated PEP and sanctions watchlist screening, and risk tier assignment at onboarding. Ongoing transaction monitoring runs velocity checks and pattern-based anomaly detection against configurable rule sets. SAR-ready reporting is built into the back-office system so compliance teams generate regulator-required reports from existing transaction data without manual extraction. AML program design — risk appetite thresholds, customer risk segmentation, transaction monitoring parameters — is documented as part of the compliance architecture brief in the Discovery phase.

Do you support crypto-friendly or stablecoin banking features?

Yes. We build hybrid fiat/crypto account architectures combining standard neobank features — fiat accounts, IBAN provisioning, card issuing — with stablecoin balance management and USDC settlement rails. Crypto features operate under the same KYC/AML compliance framework as fiat operations — there is no compliance gap in the crypto account layer. Cross-border payment flows using stablecoin intermediaries for settlement are supported for corridors where correspondent banking fees are prohibitive. Architecture is designed to absorb regulatory reclassification of crypto assets without requiring a full platform rebuild as classification frameworks evolve in the US and EU.

Who owns the source code and IP after delivery?

The client owns 100% of the source code and intellectual property at delivery. This applies equally to custom development and white-label engagements — OmiSoft does not retain licensing rights, impose ongoing usage fees, or embed clauses that limit future use or modification of the codebase. IP ownership transfer is documented in the project agreement before development begins.
