Where we come in

The problems companies bring us now, and what we sell to fix them.

  • AI agents that fail in production

    We bound what each AI agent may do and route consequential actions to a person, so it survives real workflows.

    Production-grade AI agents
  • AI agents rolled back after an incident

    A signed, versioned record of what each AI agent may do, already live in Nucleus One.

    AI governance and controls
  • RAG that answers wrong

    RAG tested against an evaluation set built from your own documents, with the source behind every answer.

    RAG accuracy and evaluation
  • Data that is not ready

    Your systems connected and records enriched before any model runs, with source systems kept authoritative.

    Data foundations and integration
  • Not enough AI engineers

    Our forward deployed engineers work inside your organisation, building on your data until the problem is solved.

    Forward deployed engineers
  • Nowhere safe to run it

    Private models and applications, hosted in the UK, EU or US, in your cloud or on-premises, run by us.

Figures from our earlier builds.

Start small, or build the platform

Choose the shape of the work. Every one follows the same route.

Custom bolt-on

One capability added to a system you already run: a RAG service, an AI agent, an API or an integration.

SuitsA team with one workflow to fix.

Modules for your platform

Modules built to your specification and standards, for a platform your own team runs.

SuitsOrganisations with their own engineering function.

Full product

A complete product: designed, built, run with you, scaled on evidence and handed over.

SuitsA business that wants the whole thing, and owns the code.

Forward deployed engineers

Two to four senior engineers embed in your organisation and build on your data and systems until the problem is solved, then hand over. We scale the team as the work needs.

SuitsOrganisations with more AI work than engineers.

Private models and hosting

Open-weight or commercial models on private endpoints, hosted in the UK, EU or US, your cloud or on-premises, run by us. Your data trains nothing unless you decide it should.

SuitsOrganisations whose data cannot leave their control.

Consultancy, systems integrator or technology provider? We take bounded specialist work on your engagements, under your brand and in your tools: a proof of concept, an integration, an evaluation, an AI agent your team cannot staff this month. We can usually start within two weeks; day rates are agreed on the call.

Partner with us

Assess. Prove. Build.

Three stages. You decide at each one.

Assess

Workflow and baseline
  1. 01

    Find the workflow

    One process worth improving and measuring.

  2. 02

    Walk through the reference build

    The closest reference build, working, and what changes for you.

  3. 03

    Establish the baseline

    How it works today, and where time, cost, error or risk sits.

You leave withA baseline, a decision to proceed or stop, and a roadmap for what follows.

Prove

Proof of concept
  1. 04

    Demonstrate

    Your own data run through the system. Two to four weeks, depending on scope.

You leave withA working system, tested against your baseline.

Build

Production and integration
  1. 05

    Define integration and controls

    Systems, access, approval points, evaluation measures and deployment agreed.

  2. 06

    Deploy and measure

    A bounded scope first, measured against the baseline, extended on evidence.

You leave withAI in production, measured and governed.

Built for production, governed by design

We choose the architecture, deployment and level of authority to suit each workflow, not a fixed stack.

Connect your systems

Document stores, databases, ERP, CRM and APIs connected, with source systems kept authoritative.

The right context

RAG where answers come from documents; ontologies and knowledge graphs where connected context is needed.

Bounded authority

Limits enforced through access, validation and tool restrictions, not prompts alone, so consequential actions reach a person.

Your deployment model

Managed cloud, private cloud or on-premises, with single sign-on, role-based access and audit logging.

Works with
  • ERP
  • CRM
  • MES
  • SCADA
  • PLCs
  • Data historians
  • Document stores
  • Databases
  • Case systems
  • APIs
  • OPC UA
  • MQTT

What buyers ask before they start

Answers to the questions we hear first.

How long does a proof of concept take?

Two to four weeks, depending on scope. Production follows once the integrations and controls are defined, and we agree that timeline with you after the proof of concept.

Where will my data be stored and processed?

We deploy solutions based on your specific requirements: on your own servers, nationally-located data centres, private cloud, or public cloud infrastructure. Where data is stored and processed follows your security, governance, and jurisdictional requirements.

Who owns the code and the intellectual property?

You do. We build for your specific problem, so the code, models and intellectual property we create for you are yours. Our model is build, operate, scale and transfer: we build it, run it with you, scale it on evidence and hand it over to your team.

How are projects priced?

On the introductory call, once we know the scope. Work ranges from a single bolt-on to a full product, so we size the price to the work and agree it in writing before anything starts.

How soon will I receive a response?

Within one working day, from a relevant domain expert.
