Atheryon - a Direct2Client Company
Using AI to Make Your Data AI-Ready
A Microsoft partner, leveraging S&P Global’s TeraHelix to deliver governed, AI‑ready data foundations for leading banks and financial institutions.
Made for you
Who We Help
Financial Markets
Transform trade, risk, and pricing data into AI‑ready pipelines for analytics and automation.
Treasury
Deliver trusted data for treasury operations, liquidity optimization, and balance sheet intelligence.
Risk & Compliance
Ensure clean, trusted data to strengthen governance and meet regulatory obligations.
The Problem
The world is moving fast. Your data isn’t.
As financial institutions race to innovate with AI, fragmented and misgoverned data is becoming an existential risk. AI systems don’t work on bad data — and organisations that fail to fix their foundations will be left behind.
AI Is an Accelerant. Good Data Takes You Forward. Bad Data Gets You Fined.
Regulatory bodies are already holding banks accountable for fragile data. In the AI era, bad data isn’t just a technical risk — it’s existential.
The Solution
Data Foundations for Every Critical Outcome
We deliver high‑quality, governed, and audit‑ready data platforms that power everything from regulatory compliance and analytics to AI and automation.
Data Migration
“Migrate faster. Trust sooner.” We use AI agents and schema intelligence to migrate legacy data into compliant, modern architectures. Automated mapping, lineage tracking, and validation mean faster cutovers, lower risk, and audit-ready confidence from day one.
Data Platform Delivery
“Deliver governed data. Power critical outcomes.” We design and build modern data platforms that produce high-quality, governed, and audit-ready assets. These platforms directly support core use cases like regulatory reporting, trade surveillance, and real-time risk management.
Capital Markets Expertise
“Product fluency meets platform thinking.” With deep experience across asset classes—from Commodities and Rates to Flow and Exotic Derivatives—we bridge the gap between quants, risk, compliance, and technology to deliver unified, AI‑ready platforms.
Trade Surveillance, Reimagined
“A strategic foundation for compliance and insight.” Our trade surveillance solutions aren’t just isolated fixes—they’re the first step in building strategic data platforms that strengthen compliance, unlock insights, and scale with your ambitions.

Why I Built Atheryon
From Industrial Automation to Financial Intelligence
I began my career automating factories.
As a mechanical engineer turned entrepreneur, I built high-precision manufacturing systems — including automated assembly machines for Siemens and Telstra — bringing industrial-grade accuracy to complex physical processes.
That instinct to simplify complexity through systems became the thread that wove through everything I would do.
In the decades that followed, I took that mindset to the heart of global finance.
At institutions like Barclays, Credit Suisse, Westpac, and CBA, I led and rescued global programs across data, risk, and surveillance. I delivered the first near real-time front-office risk system at Credit Suisse, rebuilt trust between business and technology, and embedded regulatory resilience into some of the most critical parts of global capital markets.
But as I climbed higher in finance, I saw a deeper truth:
The financial system doesn’t just run on money.
It runs on data.
And when that data is fragmented, opaque, or misgoverned — the entire system becomes fragile.
That fragility isn’t just technical — it’s existential.
It risks reputations. It invites regulatory scrutiny. It slows innovation.
That’s why I created Atheryon.
Atheryon is built on the belief that well-governed, auditable data is the foundation of successful outcomes — and that the future belongs to institutions that can move fast and stay trusted.
We start by simplifying and securing the data layer — delivering clarity, compliance, and operational strength.
Then we go further, using intelligent, agentic systems to accelerate your institution into a new era of financial operations:
- Self-optimising processes
- Autonomous monitoring
- Faster product delivery
- Higher integrity with lower overhead
Atheryon isn’t just another AI company.
It’s a financial architecture firm — one that understands that resilience and agility are two sides of the same coin.
We work with banks, asset managers, capital markets teams, and trustees — the stewards of the financial system — to help them build faster, leaner, and safer organisations.
Because in a world of exponential complexity,
the winners won’t be those with more code — but those with cleaner data and smarter systems.
