Financial Systems Technology
The Architectureof Decisions
We build intelligent systems that understand not just what happens in financial environments, but why—and what comes next.
Decades deep in the City of London & NYC. Purpose-built intelligence.
The QLS Intelligence Framework
Four Domains. One Philosophy.
Every system asks the same question: not what happened, but why—and what follows.
Regulatory Intelligence
Understanding why firms make prudential decisions—and building systems that make those decisions clearer.
Trading Intelligence
Understanding why markets misprice risk—and when structure breaks.
Behavioral Intelligence
Understanding why humans make decisions in high-stakes environments.
Emotional Intelligence
Understanding why certain experiences resonate—and others don't. Music: the shortest distance to raw emotion, after love.
Flagship Product
PRISM
MiFIDPRU Compliance. Finally Made Intelligible.
The UK's first integrated platform for ICARA synthesis, risk and prudential capital management & intelligence. Built by practitioners. Designed for the CFO's desk. Not just a living document—a living system.
The Problem with Spreadsheets
You're an MiFIDPRU investment firm. Every year, you need to calculate K-factors, prepare your ICARA with appropriate rigour, run stress tests, monitor capital and liquidity adequacy continuously, and plan for orderly wind-down.
Your current solution? Excel workbooks passed between departments. Manual calculations prone to error. Disconnected documents that don't speak to each other. A nagging sense that the FCA expects more—but no clarity on what "more" looks like.
There's a better way.
K-Factor Engine
Automated calculation across all applicable K-factors with full audit trail
ICARA Workspace
Structured document generation with embedded regulatory guidance
Stress Testing
Scenario modelling with capital impact visualisation
Wind-Down Planning
Timeline modelling, resource projection, orderly cessation analysis
Continuous Monitoring
Not annual scrambles—ongoing capital adequacy tracking
Pre-Configured Algorithms
No more uncertainty—upload your raw data, output your exact figures
Built by People Who've Been There
PRISM wasn't designed by software engineers guessing at regulatory requirements. It was built by practitioners with decades in UK financial services—including roles at the FSA/FCA, institutional trading firms, investment banks, fund managers, and multiple FCA-regulated businesses.
We've sat in the CFO's chair. We've prepared ICARAs under time pressure. We've faced the FCA's questions. PRISM reflects that experience.
PRISM enters private beta in Q1 2026. Early access available for qualified firms.
Bespoke Solutions
Precision Architecture
When off-the-shelf can't reach and spreadsheets can't cope—we architect clarity from complexity.
Some Problems Defy Conventional Solutions
Multi-party corporate structures with byzantine distribution rules. Cross-currency settlement waterfalls. Regulatory calculations too nuanced for generic software. When your operational complexity exceeds what templates and off-the-shelf platforms can handle, you have two choices: wrestle with spreadsheets forever, or architect something precise.
We build the latter.
How We Work
Understand
We start by mapping the full complexity. Not simplifying it—understanding it. The edge cases. The exceptions. The 'yes, but what about...' scenarios that break conventional tools.
Architect
Design a solution that handles the complexity natively. Not workarounds. Not manual overrides. Clean logic that reflects the actual rules.
Build
Implement with the same rigour we apply to our own products. Tested. Documented. Maintainable.
Transfer
It's your system. We ensure you can run it, extend it, and understand it completely.
Case Study
Multi-Party Investment Structure
The Challenge
A multi-party investment structure with 8 independent parties across multiple jurisdictions, 7 primary counterparties, 15 different revenue tier structures, revenue streams in GBP, USD, EUR, and CHF, tiered distribution waterfalls with priority creditors, and shared cross-party operational expenses allocated dynamically.
The existing process: a 47-tab Excel workbook. The audit trail: non-existent. The error rate: unknowable.
The Outcome
- Monthly processing time: 2 days → 20 minutes
- Error rate: unknowable → zero (tested, validated)
- Knowledge dependency: one person → documented system
We're selective about bespoke engagements, but we're always interested in problems that push the boundaries of what systems can elegantly solve.
Describe Your ChallengeThe QLS Thesis
Every Significant Decision Has Architecture
Not just the outcome—the hesitation before it, the confidence behind it, the reasoning that shaped it, the structure that preceded it.
Most technology captures the what. We're building systems that understand the why—and anticipate the what next.
Origin
Quantum Liquidity Systems was founded to bridge the gap between domain expertise and technology. Our founder has over two decades in high profile management positions in top tier finance firms in the City—from FSA enforcement division, to broker-dealers, investment banks, HFTs, fund management firms, structured product houses and EMI/PSI firms.
That experience revealed a persistent problem: the tools never matched the complexity of the work. Spreadsheets for calculations that demanded precision. Word documents for analyses that required structure. Manual processes where intelligence should flow. Zero meaningful technology solutions.
The FinSysTech Distinction
We're Not Fintech. We're FinSysTech.
"Fintech" has been captured by payment processors and neo-banks—companies building new fancy tech on top of archaic legacy bank architecture.
Financial Systems Technology (FinSysTech) creates intelligent infrastructure that understands financial environments. Not faster pipes. Smarter architecture. Systems that model regulatory frameworks deeply enough to guide decisions. Platforms that detect structural mispricings in derivatives pricing. Engines that capture the behavioral context surrounding high-stakes choices.
Our Approach
Practitioner-Built
Every system we build emerges from direct experience with the problem and a real need for a better solution. Not market research. Not customer interviews. Years of living inside the complexity we're solving.
Substance Over Surface
We'd rather build something that works deeply for a specific problem than something that looks impressive but doesn't survive contact with reality. We will never be a Jack-of-all-Trades.
Long-Term Orientation
We're not optimising for funding rounds or quick exits. We're building systems that will matter in five years, ten years, longer. The problems we solve don't disappear.
