Fintech App Development Company

What does a fintech app development company do?

A fintech app development company builds the software that moves money, manages risk, and keeps regulators satisfied. Payments and wallets, lending and BNPL, neobanking, wealth and investment platforms, insurtech, and the APIs that embed finance inside other products. The work is different from ordinary app development in one way that matters. Every feature touches money, identity, or sensitive data, so security and compliance are part of the build from the first sprint, not a review at the end.

We are an AI led team that ships regulated financial products for clients in the US and beyond. We are certified to ISO/IEC 27001:2022 and ISO 9001:2015, we are GDPR compliant, and we build for PCI DSS and HIPAA workloads. Below is what we build, how we handle compliance, the stack we work in, and the fintech platforms we have already shipped.

How Long Does It Take to Build a Fintech App?

A focused fintech MVP that proves one core flow, such as onboarding with KYC or a single payment path, typically takes a few months. A full platform with multiple money movements, compliance controls, and integrations takes longer. The variable that moves the timeline most is not the feature list. It is the compliance surface. A product that stores card data, moves funds, or handles regulated financial records needs security and audit work that a simple consumer app does not, and that work is not optional.

We front load it. In the first phase we scope the regulatory surface with you, decide which standards apply, and design the data model and access controls around them. That way compliance is built in rather than retrofitted, which is both cheaper and faster than discovering a gap during an audit.

What Does It Cost to Build a Fintech App?

Industry ranges for a serious fintech product run from roughly 80,000 dollars for a narrow MVP to several hundred thousand for a full platform, and more for anything with heavy regulatory scope. Our own published estimates start at 15,000 dollars for tightly scoped MVP work at a blended rate of 25 to 50 dollars per hour, well below the 150 to 250 dollars per hour that comparable US agencies charge. The honest driver of cost is the compliance and security surface, so we scope a fixed estimate against your real product rather than quoting a template.

How Do You Handle Security and Compliance?

We treat compliance as an engineering requirement, not paperwork. Depending on your product we build for:

• PCI DSS 4.0 for anything that touches cardholder data, with tokenization so raw card numbers never sit in your systems.
• KYC and AML with identity verification and transaction monitoring, integrated with providers such as Onfido and ComplyAdvantage.
• Open banking rules, including the US CFPB Section 1033 data access rule and PSD2 strong customer authentication for the EU.
• Data protection under GDPR and CCPA, with encryption in transit and at rest, role based access, and full audit logging.
• Passwordless and passkey authentication with biometric and multi factor options as the 2026 baseline.

We are ISO/IEC 27001:2022 and ISO 9001:2015 certified, and we build for PCI DSS and HIPAA workloads. We do not claim PCI DSS certification, and we are clear about the difference.

Which Payment and Banking APIs Do You Integrate?

We integrate the payment, banking, and identity infrastructure your product needs rather than pushing one vendor. Stripe and similar processors for payments and checkout, account aggregation and open banking connections for balances and transactions, banking as a service providers for neobanking front ends, and KYC and AML providers for onboarding and monitoring. Where a partner bank or processor is already chosen, we build to their APIs and their compliance requirements.

Can You Take Over or Secure an Existing Fintech App?

Yes. A large part of fintech work is inheriting a product that grew faster than its foundations. We audit the codebase for security and architecture risk, close the gaps that matter, and stabilize it before adding features. If you built an early version on a no-code or AI assisted stack and hit a wall on control, cost, or compliance, we can secure it, scale it, or migrate the parts that need to move onto a system you own.

How We Deliver

We are an AI native team, and roughly 80 percent of our production code is AI generated and engineer reviewed, verified by our internal team. In fintech that speed is paired with review discipline, because a fast build that fails an audit is not fast. We start with a compliance scoped discovery, build the core flow, prove it, and expand. You own the full source, documentation, and infrastructure from day one.
