Neobank development

Launch a neobank with a team that knows banking regulation and mobile

A neobank — or neo bank, or challenger bank — is a banking product, a mobile product and a compliance program at the same time. As a neobank development company, Itexus has built digital banking apps for founders serving specific communities — migrants, students, fee-averse consumers — and white-label mobile banking apps for a Silicon Valley digital banking platform provider.

We help choose the operating model first: a sponsor bank and BaaS provider, a white-label platform, or a licensed core. Then we build the apps, the integrations and the back office your operations and compliance teams need from day one.

  • BaaS and core integration — accounts, cards and payments through your banking partner’s APIs
  • Onboarding and KYC — document verification, biometrics and risk checks in minutes
  • Native mobile engineering — Swift and Kotlin, or Flutter for a shared codebase
  • Back office included — support, compliance and operations consoles

How we work

How we build neobank apps

Agile flexibility with the scope, budget, risk and delivery governance that regulated financial projects require.

  1. Discovery and blueprints before code

    Requirements, architecture, integrations, API contracts and delivery assumptions are defined upfront and updated with every release.

  2. Agile with scope and budget control

    Short iterations and demos, combined with controlled scope management, budget tracking, release planning and risk reporting.

  3. AI-first build for new products

    With modular architecture, documented requirements and clear guardrails, AI agents accelerate coding and test generation under senior architect review.

  4. AI-accelerated work on legacy systems

    For tightly coupled systems with incomplete documentation: AI-assisted analysis, refactoring and test generation with closer manual oversight.

  5. Quality engineering and test automation

    Manual and automated QA, regulatory scenario testing, penetration testing, performance and load testing.

  6. Launch and post-launch support

    Deployment, monitoring, L2/L3 maintenance and knowledge transfer. Current documentation keeps later changes fast and safe.

Engagement models

Recommended

Agile with budget control

Agile delivery in two-week sprints combined with strict control of scope, budget, risks and quality.

  • High-level scope, estimate and budget defined upfront
  • A demo of new features at the end of every sprint
  • Requirements can change as new ideas come up
  • Weekly reporting on costs and progress
  • Only efficient hours within the agreed estimates are billed

Fixed price

All requirements are documented and signed before the project starts. Itexus delivers the agreed scope for the agreed price and time.

  • Exact scope and functionality fixed in the contract
  • Payments on reaching milestones
  • Minor client involvement during implementation
  • Suits clients who can specify the software in detail and do not plan to change it

Dedicated team / outstaffing

Remote engineers, with or without a project manager, integrated into your in-house team and managed by you day to day.

  • You direct the development process
  • Developers, QA, DevOps, designers, data scientists
  • Engineers with financial domain knowledge
  • Scale the team up or down as the roadmap changes

As a general reference, discovery and prototyping engagements start from around $30,000; enterprise fintech projects often range from $150,000 to $1,000,000+. Compare the cooperation models in detail

FAQ

Neobank app development: frequently asked questions

How much does it cost to develop a neobank app?

It depends on the operating model, feature set, number of platforms and integrations with your banking, card and KYC partners.

As a general reference, discovery, validation and prototyping engagements start from around $30,000. Enterprise projects involving legacy integrations, regulated workflows, AI functionality or full-scale product development often range from $150,000 to $1,000,000+. Itexus provides a detailed estimate after an initial discovery session and technical scoping.

Do we need a banking license to launch a neobank?

Not necessarily. Many neobanks launch through a sponsor bank and a banking-as-a-service provider, which hold the license and provide accounts and cards via APIs. Which model fits depends on your market and product; this is a legal and business decision that we help you evaluate from the technical side during discovery.

Can you build on a white-label platform to launch faster?

Yes. Itexus offers a white-label digital banking foundation with onboarding and KYC, accounts and statements, payments and transfers, cards with limits and controls, budgeting insights and notifications. It is customized to your brand and extended with your own features.

Which BaaS and core banking systems can you integrate with?

We integrate with the APIs of your chosen banking-as-a-service provider or core. Itexus has worked with Temenos, FIS and Fiserv cores and has built apps on a Silicon Valley provider’s SaaS digital banking platform.

Do you build both iOS and Android apps?

Yes — natively in Swift and Kotlin, or with Flutter or React Native when a shared codebase is the better trade-off. We also build the backend, integrations and web back office.

Can you take over an unfinished neobank project?

Yes. Itexus takes over stalled, underperforming or poorly documented projects from other vendors.

The work starts with an audit of the codebase, architecture, documentation, integrations, infrastructure and security risks, followed by a remediation plan covering technical debt, testing gaps and the next development priorities.

Do you work with early-stage fintech startups?

Itexus primarily focuses on financial services companies, funded fintechs and organizations building complex or regulated financial products.

We also work with selected early-stage startups when there is a validated concept, clear compliance context, realistic budget and a product roadmap aimed at institutional scale.

Do you provide post-launch support and maintenance?

Yes. Itexus provides post-launch support and maintenance for production financial systems, including L2/L3 support, monitoring, incident response, patch and release management, performance tuning, backup and rollback support, and ongoing improvements.
