Discipline 7 of 11

Financial technology

In financial software, a subtle bug is not a bug. It is a loss. Everything here is built with that assumption.

Capital systems, engineered.

Financial technology
01The discipline

We develop the systems that sit between a strategy and real capital: research and backtesting infrastructure that doesn't lie to you, execution with position sizing and fail-safes, risk limits that actually halt trading, and the analytics that explain where returns and exposure came from. Traditional venues and digital assets, with the same standard of rigour applied to both.

Put plainly

Software that manages, moves and grows money, with the testing and safety controls that serious capital requires.

What changes

01

Backtests you can trust, because slippage and bias are modelled

02

Execution that behaves identically at 3am and at month-end

03

Risk limits enforced by the system rather than by discipline

03What you get
  • Strategy specification with statistical validation plan
  • Market data pipeline and historical research environment
  • Backtesting engine with realistic fees, slippage and latency
  • Live execution, order management and reconciliation
  • Risk controls, kill switches and an operator dashboard
04The set

11 services in this discipline

Each one is a scope we can run on its own or fold into a larger build. Open any of them for the detail.

Questions we get asked

06How it runs

A delivery model built to remove surprises.

01

Diagnose

A paid, fixed-scope discovery. We interview your team, audit the current stack and data, and write down what's actually happening, not what the org chart says. You leave with findings you can use even if you never hire us again.

02

Architect

We design the solution before building it: scope, system design, integration points, risks, sequence and a fixed commercial. Every assumption is written down so there is nothing to renegotiate later.

03

Build

Two-week cycles with a working demo at the end of each one. You get a shared board, a single point of contact, and an environment you can click through from week two onward.

04

Operate

Handover with documentation, training and monitoring, then a support agreement if you want one. We instrument what we build, so improvement is measured rather than claimed.

Next step

Tell us the outcome, not the tooling.

Send us the situation you are in. We will tell you which discipline it belongs to, what we would do first and what it costs, including when the answer is to wait.
