If It Won’t Survive an Audit, It Won’t Survive Production.
Regulated environments do not tolerate architectural shortcuts. Assess your systems before regulators or auditors do. Strengthen compliance posture. Reduce operational risk. Ensure your infrastructure stands up to scrutiny.
Software engineering for regulated environments
Financial services software is an engineering discipline with regulation as a first-order design constraint. BaFin, FINMA, FCA, and MAS requirements shape architecture decisions, data handling, and deployment processes in ways that general-purpose software teams consistently underestimate. For a financial services client, the question is not whether the engineering partner can build the system - it is whether they understand the audit environment it has to operate in.
Gradion builds financial services software with ISO 27001 certified processes across a team with 23 years of delivery in regulated environments across the DACH region, Southeast Asia, and Africa.
Compliance as Architecture, Not Afterthought
In regulated finance, compliance cannot be retrofitted. It must shape system design from the first line of code.
Our financial engineering practice embeds:
- Audit-ready logging and traceability
- Segregation of duties within deployment pipelines
- Secure data handling and encryption standards
- Role-based access control and least-privilege design
- Documented change management aligned with supervisory expectations
This reduces regulatory friction and shortens audit cycles.
Built for Transaction Integrity at Scale
Financial systems do not tolerate inconsistency.
We design for:
- High-volume transaction processing with deterministic reliability
- Zero-downtime deployment strategies
- Multi-cloud resilience with regulatory alignment
- Continuous security monitoring and vulnerability management
- Operational continuity under peak load and market volatility
In regulated finance, uptime is not a performance metric. It is systemic risk management.
Core banking & credit infrastructure
A Swiss provider of digital credit solutions serving banks, insurers, and pension funds re-architected its decade-old credit lifecycle platform with Gradion in eight weeks. Compliance, security hardening, and audit readiness were built in from the start. The new architecture passed a Big Four security and compliance audit without material revisions.
A Swiss banking technology provider running the infrastructure behind dozens of retail banks engaged Gradion to review its entire application estate, design a compliant multi-cloud migration path, and enable Instant Payments - without disrupting a platform processing half a million transactions daily.
Lendico built P2P lending operations across Germany, the Netherlands, Switzerland, and Brazil with Gradion.
Technology acquisition
When ING-DiBa acquired Lendico, the deal was described not as a customer acquisition, but as a technology acquisition.
Payments infrastructure
Switzerland’s leading mobile payment app processes 64% of all digital payments in Switzerland. Gradion built the multi-platform plugin framework that lets thousands of merchants integrate Switzerland’s leading mobile payment app consistently across Shopware, WooCommerce, and Magento through a standardized SDK.
A leading DACH payment infrastructure provider processing billions annually for tens of thousands of merchants, needed its platform repositioned for a PE exit. Gradion redesigned the merchant portal and developer experience.
Payments at scale
64% of all digital payments in Switzerland flow through Switzerland’s leading mobile payment app - Gradion built the plugin framework powering merchant integrations across every major e-commerce platform. For a leading DACH payment infrastructure provider processing billions annually, redesigning the merchant portal and developer experience delivered a €1.4× valuation uplift ahead of a private equity exit.
Identity verification at enterprise scale
IDNow, one of Europe's leading AI-powered identity verification providers, has run a 15-engineer Gradion team embedded across its backend, mobile, and machine learning organization for multiple years - delivering KYC capabilities at enterprise scale in a highly regulated environment.

Beyond DACH
A Sudanese fintech startup needed to serve users in a market with unreliable internet infrastructure. Gradion delivered Sudan's first offline NFC digital wallet in five months. A separate engagement delivered a crypto-native wallet platform with real-time AML compliance built on the same core banking stack used by N26 and Revolut.
