For brokerages, wealth managers and fintechs

Cloud and software engineering for regulated financial platforms. We build the systems that have to pass audit.

A small team of senior engineers. We design, build and secure trading, wealth and investment platforms, with the controls, evidence and documentation your auditors and regulators will ask for.

01What we do

Three areas of work, held to the same standard of evidence.

Most engagements combine product and platform work. Every one ends with systems your team can operate and controls your auditors can test.

01.1PRODUCT

Fintech product engineering

Brokerage, wealth and investment platforms, built with the audit trail in the data model from the first release.

  • Account, portfolio and order services
  • Custodian, execution venue and bank integrations
  • Append-only records and reconciliation
Product engineering →
01.2PLATFORM

Platform and compliance engineering

Cloud foundations where controls are enforced in code and audit evidence is produced as a by-product of normal work.

  • Multi-account AWS, Kubernetes and GitOps
  • Private connectivity and policy-as-code
  • Records retention and SOC 2 readiness
Platform engineering →
01.3APPLIED AI

Applied AI for financial services

Governed, logged use of language models inside firms that have to explain how every decision was made.

  • Secure LLM integration
  • AI usage governance
  • Workshops for engineering and risk teams

02How we work

Four principles we hold ourselves to on every engagement.

They shape how we scope, staff and hand over work, and they're the standard to hold us to.

  1. 02.1

    Compliance designed in

    Audit trails, access boundaries and retention are part of the first design review, not a remediation project the month before an audit.

  2. 02.2

    Senior engineers do the work

    The people you meet when scoping are the people who write the code and run the change reviews. There is no hand-off to a junior bench.

  3. 02.3

    Everything documented

    Architecture decisions, runbooks and control evidence ship with the code, written so your team and your auditors can both use them.

  4. 02.4

    Honest scoping

    We tell you what we would cut, what it will cost and when we're not the right fit. Fixed scopes where possible, written assumptions where not.

04Ways to start

Start with a defined piece of work.

Each starting point has a fixed scope and a written output, so you can judge how we work before committing to more.
