About Arx Engineering

Consulting and software for regulated financial environments - from risk and governance to ISO 20022 payment integration.

Arx Engineering AB is a Stockholm-based consultancy working at the intersection of financial risk, regulatory change, and complex program delivery. We support banks and other financial institutions when the stakes are high and the path forward is not obvious.

Our work combines quantitative analysis with governance, compliance, and execution. That means helping clients assess and model risk, lead transformation programs, establish interim leadership where continuity matters - without losing sight of what regulators, auditors, and internal stakeholders need to see.

Financial Risk Management

Risk assessments, modeling, reporting, and capital optimization for regulated businesses - across market, credit, and operational risk.

Project Management

Senior delivery leadership for complex initiatives - including new or stranded programs where software, infrastructure, or regulatory change must land on time and within budget.

Interim Work & Governance

Strategic leadership and governance support during transitions, reorganizations, and other major changes where clear decision-making and continuity are essential.

Alongside consulting, we develop i22-MBA - an on-premises ISO 20022 multi-bank adapter for Sweden's migration from legacy Bankgirot formats. Organizations describe payments and statements once in a neutral internal format; i22-MBA converts to and from each bank's XML, supports dual-run validation during cutover, and includes a local data scrambler for safe testing and support.

The adapter is designed for sensitive environments: all processing stays on your infrastructure, with offline licensing and no vendor cloud dependency.

To give organizations practical consulting and software that turns regulatory and operational complexity into measurable outcomes - with clarity, rigor, and delivery that holds up under scrutiny.

Rigor

We ground recommendations in evidence - whether that is a risk model, a program plan, or a payment conversion pipeline - and make assumptions explicit.

Integrity

We operate with transparency in regulated environments, respecting confidentiality, audit trails, and the constraints your organization actually faces.

Practical delivery

Strategy only matters if it ships. We stay close to execution, working alongside your teams until the change is embedded and the outcome is verifiable.
