Post-Trade Risk Management,
Accelerated
Decades of banking expertise, amplified by agentic development.
Same calibre. New velocity.
The Accelerator
What is Meridian?
Meridian is JUXT's accelerator for equity derivatives post-trade risk management. It's not a blank-slate build and it's not an off-the-shelf product. It's a deeply opinionated head start, shaped by our collective decades of building highly scalable, performant systems inside investment banks.
Its modular architecture is designed to plug directly into an existing banking ecosystem, integrating with your settlement, clearing and regulatory reporting workflows without demanding you rip out what already works.
Meridian isn't AI-generated software. It's what happens when senior engineers with decades of banking experience adopt a disciplined agentic workflow — encoding the patterns we know work at scale in production: immutable data, deterministic computation, and full reproducibility of every risk calculation, every position, every trade lifecycle event.
Foundations
Built on First Principles
Immutability
Every state transition is preserved. Data is never overwritten, only appended. The complete history of every position and risk calculation is always available, making audits trivial and regulatory queries a matter of query, not archaeology.
Determinism
Given the same inputs, Meridian produces the same outputs. Always. No hidden state, no order-dependent side effects, no "it works on my machine". Risk numbers you can explain to regulators with confidence.
Reproducibility
Rewind to any point in time and replay. Reproduce yesterday's P&L. Rerun last quarter's risk with today's models. Time-travel is a feature, not a fantasy.
Modularity
Meridian doesn't ask you to replace your infrastructure. Its modular design slots into your existing ecosystem: your OMS, your market data feeds, your clearing and settlement pipelines. Adopt what you need, leave what you don't.
How We Build
Agentic Development,
Applied to Hard Problems
AI amplifies. JUXT brings the engineering discipline and domain expertise. Agentic development is the multiplier.
Rigour at Velocity
Senior engineers paired with AI, moving at startup speed with investment-bank discipline. Every feature goes through formal design, specification, and review before a line of code is written. The AI doesn't replace engineering judgement — it multiplies it.
Domain Expertise, Amplified
Complex derivatives systems demand deep understanding — pricing models, risk calculations, regulatory constraints, CDM standards. JUXT brings decades of experience building these systems at Tier 1 banks. Agentic development means that expertise is delivered faster, not diluted.
Confidence in the Output
Every feature is formally specified before implementation. The engineering bar — exhaustive testing, behavioural specifications, architectural rigour — is higher than most hand-built systems. It just gets there faster.
See it in Action
Meridian in Motion
JUXT has spent years embedded in Tier 1 investment banks, building the systems that underpin trading desks, risk engines, and post-trade infrastructure. We know what breaks at scale and what survives.
Meridian encodes that experience. It's not a theoretical exercise. Every architectural decision reflects real lessons learned from real production systems handling real volumes in real regulatory environments.
The engineer holds the standard. The AI handles the breadth. Built agentically, Meridian represents a new approach to accelerator development: our senior engineers' experience and judgement, amplified by AI, producing a system with the depth and rigour of a multi-year build in a fraction of the time.
