Fintech software built for compliance.
Your audit team will not need to rebuild it.

We build payment infrastructure, SaaS fintech products, and enterprise financial platforms for CTOs who cannot afford a compliance failure. PCI-DSS, SOC 2, and GDPR are architecture requirements on every project. They are never an afterthought.

Why Fintech Builds Break

The compliance gap shows up
in production. Not in the spec.

68%

of fintech startups miss their first compliance audit

Most teams plan for features, not compliance. PCI-DSS and SOC 2 requirements enter the project six months late, costing three times the original estimate to retrofit.

$4.4M

average cost of a financial sector data breach (2023)

Encryption, tokenization, and access control are decisions you make at the architecture stage. A system not built for them cannot be patched to comply later.

14 mo

average time to rebuild a legacy payment system

Payment rails built before 2015 cannot handle real-time settlement, open banking APIs, or embedded finance. The rebuild clock starts the moment you try to add those features.

What fintech CTOs say at sprint 8
"We built fast. Now we need six months to add two-factor auth because the session layer was never designed for it."

Five Ways We Build Fintech Software

Payment infrastructure, SaaS, mobile, modernization, APIs. One compliance standard across all of it.

We build payment rails, gateway integrations, and reconciliation systems for platforms processing $10K to $10M per month. Stripe, Braintree, Adyen, and custom ACH/SEPA implementations are all standard scope.

Subscription billing with proration, upgrades, and automatic retry on failed payments (dunning)

We build multi-tenant financial SaaS platforms for lending portals, wealth management dashboards, insurance aggregators, and B2B spend management tools. Each client's data stays isolated from other tenants. White-label configuration ships as standard.

Tenant-isolated data — one client's data never touches another's
Usage-based and seat billing models
Financial reporting and PDF generation
Plaid, MX, and Open Banking connectors

We build fintech apps for consumer wallets, neobank companions, investment tools, and peer-to-peer transfer platforms on iOS and Android. Biometric authentication, in-app card management, and real-time balance updates ship as standard features.

Biometric auth (Face ID, fingerprint)
Apple Pay and Google Pay integration

We modernize payment systems built before 2015 using a parallel-run migration strategy. New infrastructure takes on increasing transaction load while the legacy system handles the rest. There is no risky, all-at-once cutover.

Zero-downtime migration with traffic splitting
API layer over legacy core banking — no rebuild required to expose new services
Data migration with full reconciliation validation
Compliance audit trail for every migrated record

We build PSD2-compliant Open Banking APIs and Plaid/MX bank account aggregation. Non-financial SaaS products use our embedded finance infrastructure to add payment capabilities without becoming a regulated entity. Full OpenAPI documentation ships with every delivery so your team can extend the API without us.

Client

USA School System Platform

Educational Payment Platform

StripePayPal.NET + PHP

A large school management organization needed one financial hub to handle donations, school fees, and ecommerce. Three separate payment systems were creating reconciliation errors and leaving transaction data exposed.

The Problem

School fees, donations, and ecommerce each ran on a different system. Reconciliation happened manually. There was no fraud prevention, no tokenization, and no single view of payment activity across the organization.

No unified payment layer. Manual reconciliation across 3 systems. No fraud prevention or tokenization.

The Result
$0K

in reported monthly platform growth after consolidating to one PCI-compliant payment system with Stripe and PayPal, recurring billing, and full transaction monitoring

Stripe and PayPal unified under one tokenized payment layer

Recurring subscriptions, one-time payments, and multi-transaction types handled automatically

Encryption, audit logging, and fraud scoring active from launch day

What Sets Redefine Apart

Compliance-ready fintech development means
compliance is built in first. Here is what that looks like in practice.

Most agencies add compliance after the code ships. That is when it costs the most and breaks the most. We treat PCI-DSS, SOC 2, and GDPR as architecture requirements. They are in scope before a single line of payment code is written.

Fintech Buyers Ask

What fintech teams ask before committing to a build partner.

Compliance standards, IP ownership, security requirements, and timelines are what fintech buyers need answered before they engage. These are the direct answers.

Pricing approach

Scoped before work starts. A proposal requires no commitment.

A fintech discovery sprint delivers a full security architecture document and compliance requirements matrix. You see every line item before signing anything.

Yes. Scope isolation is our default. We never store raw card numbers. Tokenization vaults (Stripe, Braintree, or custom hardware-backed) hold cardholder data, so your system's compliance scope is minimized from day one. We document the cardholder data environment boundary during the architecture sprint, before any code is written. That documentation becomes the starting point for your QSA relationship.
SOC 2 Trust Service Criteria map to architecture decisions in the discovery sprint. Audit logging, access control, availability monitoring, and change management processes are designed in from the start. At handoff, we deliver a controls documentation package: what was implemented, where, and why. It is written for the auditor, not just the engineering team. This cuts your Type II preparation time from months to weeks.
You own everything. Code goes into your repository throughout the engagement. Payment integration credentials, webhook signing secrets, and API keys are yours from day one. Architecture documentation, security runbooks, and audit trail records all transfer to your team at handoff. You will not need us to operate the system or pass a compliance review after the project closes. That is a delivery requirement on every fintech project, not an option.
Timelines depend on scope, but here are the ranges we see consistently. Discovery and architecture sprint: 2 weeks. Payment integration with basic subscription billing: 8 to 12 weeks. Full consumer fintech app with KYC, wallet, and push notifications: 16 to 24 weeks. Enterprise financial SaaS with multi-tenancy, reporting, and compliance documentation: 20 to 32 weeks. Legacy payment modernization with parallel-run migration: 12 to 20 weeks, depending on data volume. Every project begins with a week-by-week sprint plan showing deliverables and compliance milestones.
Yes. We use a parallel-run migration strategy where new infrastructure takes on a growing share of transactions while the legacy system handles the rest. Both run at the same time during verification. Reconciliation confirms consistency before we increase the cutover percentage. We never flip a switch. The final cutover is a deliberate, monitored action with automated rollback if any metric drops below threshold.
Is This the Right Fit?

Select what describes your fintech project.

We are honest about fit. Fintech projects with unrealistic compliance timelines or budget constraints are the ones that fail in audit. We say so upfront.

Building a platform that will process real payments or hold user financial data

PCI-DSS, SOC 2, and GDPR requirements must be in the architecture from day one.

Need to pass a compliance audit in the next 12 months

Architecture designed for audit means your QSA review starts with documentation, not remediation.

SaaS fintech product targeting institutional or enterprise customers

Multi-tenancy, data isolation, SOC 2, and dedicated reporting are baseline requirements for institutional procurement.

Existing payment system that needs modernization without taking the platform offline

We migrate using a parallel-run strategy. Your old system keeps running. New infrastructure takes on more traffic over time. No forced cutover.

Probably not the right match if:

You need a payment integration added to an existing ecommerce site in under 2 weeks

Shopify and WooCommerce have pre-built integrations that are faster and cheaper for this scope.

Total project budget under $15,000

A production-ready compliant financial platform requires real architecture time. We cannot compress below the minimum.
