The technology behind serious capital. Built to fit, not to compromise.

Strategy engines, backtesting infrastructure, broker integrations, risk controls and live dashboards — designed, coded and shipped by engineers who've built for funds, prop desks and fintech teams before.

Why not just buy a licence

Off-the-shelf platforms bend your strategy to fit their menu. We build the platform around your edge.

The SaaS shelf

  • A generic indicator set, whether or not it fits how your desk actually trades.
  • One-size risk rules, applied the same way to every strategy on the platform.
  • Your logic, translated into someone else's proprietary scripting language.
  • A roadmap decided by their other customers, not by your desk's priorities.
  • Your IP, sitting on somebody else's servers, under somebody else's terms.

A bespoke build

  • An engine designed around your exact logic, indicators and edge cases.
  • Risk rules that mirror your desk's actual playbook, strategy by strategy.
  • Source code and IP that are fully yours from day one.
  • A system that ships to your infrastructure, your brokers, your data vendors.
  • A build that evolves as your strategy does, not on someone else's release cycle.
Build track 01

A scripting layer built around how your desk actually thinks.

Every desk has its own shorthand for describing a trade — a mix of indicators, filters and conditional logic that's evolved over years. We build a declarative scripting layer modelled on that shorthand, so your traders and quants can express strategies in a language that already makes sense to them. Where the logic gets more exotic, we drop into fully custom Python or C++ — same engine, no ceiling.

  • Custom scripting layer

    A declarative rules engine — arthLang, or a syntax modelled on your own vocabulary — for fast, readable strategy definitions.

  • Market data access

    Live and historical feeds wired directly into the engine, so strategies read price, volume and custom signals without extra plumbing.

  • Risk controls, built in

    Position sizing, exposure limits and execution rules engineered into the strategy layer itself, not left to a separate system.

  • A path to deployment

    A route from editor to paper to live that doesn't require handing your code to another team.

Build track 02

Prove it on ten years of data before it touches one live dollar.

We build simulation environments that replay years of historical market data against your strategy logic — tick by tick, or bar by bar — and surface the metrics that actually predict how a strategy behaves live.

Performance metrics engineering

Custom-built reporting on returns, drawdowns, Sharpe, Sortino and every risk-adjusted metric your desk actually reviews.

Historical data pipelines

Ingestion and normalisation pipelines across equities, derivatives, crypto and forex, however many years back your edge needs testing.

Deep analysis tooling

Walk-forward testing, parameter optimisation and strategy breakdowns built to catch overfitting before the market does.

Build track 03

Prove it live, without a single dollar at risk.

Before a strategy touches real capital, we build a sandbox that mirrors live market conditions exactly — same data feeds, same execution logic — so your team can refine with confidence.

  • Strategy refinement

    Tweak, re-test and refine instantly, in an environment built to mirror production.

  • Real market simulation

    Strategies act on live data and real conditions — without capital on the line.

  • Performance tracking

    P&L, logs and consistency metrics tracked the same way they will be once you go live.

Build track 04

Your strategies, connected to the brokers you already trust.

We engineer the bridge between your strategy engine and the brokers or exchanges your desk trades through — secure API connections, real-time order sync, and capital allocation across single or multiple accounts.

Secure API integration

Encrypted, auditable connections into your broker and exchange APIs.

Real-time sync

Positions, fills and balances stay in sync across every connected account.

Multi-account support

Route and allocate capital across single or multiple broker accounts from one system.

Instant execution

Orders dispatch the moment conditions are met — no manual hand-off.

Build track 05

Capital protection, engineered into the execution path.

We build risk controls that sit inside the trade lifecycle, not bolted on as an afterthought — so every order that leaves your system has already passed the checks your desk defines.

Pre-trade controls

Per-strategy capital limits, max trade size and exposure thresholds enforced before an order ever reaches the broker — consistent across paper and live environments.

Exit logic engineering

Stop-loss and target rules built per strategy, in absolute or percentage terms, so exits stay disciplined even when the market isn't.

Risk analytics

Live exposure dashboards and post-trade breakdowns that show exactly where your risk sits, strategy by strategy.

Build track 06

Visibility your whole desk can read at a glance.

We design and build the dashboards that sit on top of your trading systems, with the controls to pause or stop a strategy the moment something looks off.

Real-time insights

Track P&L, holdings and performance the moment it happens.

Risk monitoring

Live exposure and trade-level risk metrics, surfaced the way your desk needs to see them.

Instant control

One-click pause and stop controls, engineered into every strategy we deploy.

Our engagement process

From first call to live capital, in five stages.

01

Discover

We start with your strategy, stack and constraints — not a demo of our product.

02

Design

We spec the engine, data pipeline, broker connections and risk layer with your team.

03

Build

Our engineers build against that spec, in regular check-ins you can see and test.

04

Validate

Every build ships with backtesting and paper trading before it touches live capital.

05

Launch & support

We deploy to your broker connections and stay on to monitor, tune and extend.

Beyond the tech stack

The problems that don't show up in a pitch deck.

Most of what slows a lean fund down isn't a missing indicator — it's the operational weight sitting around the strategy. We build for that too.

No more key-person risk

When your edge lives in one quant's local scripts, the fund is one resignation away from a crisis. We turn that logic into documented, versioned infrastructure the whole team can maintain.

Investor-ready reporting

Performance, exposure and risk data that hold up to LP and allocator scrutiny — clean and consistent, not assembled the night before a call.

Audit trails, not fire drills

Every trade, risk check and system change logged and traceable, so a regulator query or investor audit doesn't send your team scrambling for evidence.

Scale without scaling headcount

A two-person desk running the infrastructure of a firm ten times its size — without hiring a full engineering team to maintain it.

How we work together

Three ways to bring us onto your desk.

Fixed-Scope Build

A defined system, a defined spec, a defined timeline. Ideal for a single strategy engine, backtester or integration.

  • Fixed price & timeline
  • Full source code ownership
  • Post-launch bug-fix window

Frequently asked

Questions worth asking before you hire a build team.

Who owns the code once the build is done?

You do, entirely. Every line of code, every strategy definition and every piece of documentation we build transfers to you at the end of the engagement, under a full IP assignment.

Do you ever trade our capital or see our strategy logic?

We never trade on your behalf or take a position in your strategy's performance. Your logic is covered by NDA from our first call, and we're happy to work inside your own infrastructure if that's a requirement.

How long does a typical build take?

A single build track — a backtester, a broker integration — usually ships in 4 to 8 weeks. A full strategy-to-live pipeline is closer to 3 to 4 months, depending on scope.

Can you work with our existing codebase?

Yes. Most engagements plug into an existing stack rather than starting from a blank slate — we'll audit what you have before proposing what to build.

Which markets and brokers do you support?

We've built for equities, derivatives, crypto and forex, and integrated with brokers including Interactive Brokers, Binance and Alpaca, among others. If your broker exposes an API, we can very likely connect to it.

What if our strategy is still evolving?

Most are. We design systems to be extended, not just delivered — our retainer and dedicated-team engagement models exist specifically for desks that iterate continuously.
