Software studio  /  North West, UK wide

Software built from scratch. Data made decisive.

We architect and ship complete production systems: multi-tenant SaaS, native mobile, event-driven cloud infrastructure defined in code, and the AI pipelines that make dense, domain-specific data legible enough to decide on.

Nine years across defence, national security and regulated industry, building the systems that do not exist off the shelf.

Case study

A national trade platform, live in under 16 hours.

A diplomatic mission needed a working platform for a House of Lords luncheon. Not a holding page: strategy content, an investment project index with sector filtering, a partners hub, a confidential submission channel, and an AI guide grounded on ministry material that cites its answers and refuses anything out of scope.

It went live on a custom domain, on serverless infrastructure defined in Terraform, before the event opened. Three printed artefacts were designed and produced for the room in the same window.

Talk about a deadline like this
  • Hour 0

  • Hour 9

    Strategy, investment index and partners hub built and populated.


  • Hour 13

    AI guide grounded on ministry material, refusing out-of-scope questions.

P-01

Music intelligence platform for A&R

A major record label

Finds pre-breakout artists and undervalued catalogue by reading narrative, cultural cohort and scene infrastructure, the signals that purely quantitative tools structurally miss. Eleven live data sources behind one view.

AI production engine for property marketing

A property marketing studio

Turns a verbal brief into finished collateral. A structured intake replaces the brief that never gets written, and the engine regenerates brochures, logos and floor plans in minutes rather than days.

What we build

Four things, done properly.

No staff augmentation and no fragments of someone else's spec. We take responsibility for the whole product.

01

Complete product builds

From an empty repository to a live product taking payments. Multi-tenant architecture, identity and access, billing, background processing, native mobile from a shared codebase, and the admin surface nobody remembers to scope.


  • Multi-tenant SaaS architecture
  • React Native and Expo, one codebase
  • Stripe billing and metering
  • Cognito and OIDC identity

02

Data and intelligence platforms

Ingesting high-volume, contradictory, domain-specific sources and resolving them into something a person can decide on. Entity resolution, ranking, geospatial and graph analysis, and interfaces that survive contact with a real analyst.


  • Multi-source ingestion pipelines
  • Entity resolution and deduplication
  • Elasticsearch and vector search
  • Graph and geospatial analysis

03

Applied AI engineering

Production multi-agent systems, not proofs of concept. Schema-enforced prompts, retrieval grounded on your own corpus, model routing for cost against accuracy, and full tracing so you can see why the machine said what it said.


  • Multi-agent orchestration
  • Retrieval-augmented generation
  • Schema-enforced structured output
  • Tracing, evals and LLM-as-judge

04

Systems that must hold up

For work that gets audited, litigated or regulated. Tamper-evident logging, calibrated confidence, infrastructure defined in code and reproducible, and offline or air-gapped delivery where public services are ruled out.


  • Tamper-evident audit trails
  • Terraform, reproducible estates
  • Offline and air-gapped delivery
  • ISO 27001 programmes

How we work

Phase gated, so you can stop at any gate.

Every phase is separately commissionable and priced before it starts. Ownership transfers to you on payment, in writing, and nothing is locked to us.

  • 01

    Scope

    A fixed-price week that turns an idea into a costed, phase-gated plan you could hand to anyone.

  • 02

    Build

    Working software in front of you every week. Phases are separately commissionable, so you can stop at any gate.

  • 03

    Ship

    Deployed on infrastructure defined in code, with tests, monitoring and a handover that means you are not locked to us.

  • 04

    Run

    Ongoing care, or a clean handover to your team. Ownership transfers to you on payment, in writing.

Trust

Everything you would ask in due diligence.
