Companies we've worked with

Established companies across fintech, HR tech, and travel have put our machine learning into production.

What went wrong last time, and what happens here

The complaints below are the ones we hear on first calls and read in the practitioner forums, in the words people use. Beside each one is how we work so it does not happen again.

How common the last project is, from three published surveys:

The questions we put to every proposal, including our own, are written up as a checklist you can use before funding anything. Ten questions to ask before you fund an AI pilot

Where are you right now?

Four ways this usually starts. Pick the one that sounds like your week.

From the first call to a result you can measure

What the first six weeks look like, and what each step costs before you commit to the next one.

  1. Day 0 A 30-minute call

    You describe the problem. We tell you whether we can help, and say so plainly when we cannot.

    No obligation
  2. Within a week A written scope

    What we would build, what it needs from you, and a fixed price. Or a short note saying this is not worth doing.

  3. Weeks 1 to 4 Validation

    A proof of concept with weekly milestones, built on our infrastructure so an IT security review is not on the critical path.

    Fixed price
  4. End of week 4 Go or no-go

    A decision with the measurements behind it. No-go is a real outcome and it has happened.

  • Then: we build it

    We write it, integrate it and put it into production on your infrastructure.

    • Two-week milestones, with a working demo at each one
    • AWS, GCP, private VPC or on-premise where data sovereignty requires it
    • Risk is shared between both sides
    Development and implementation
  • Or: your team builds it

    We design the architecture and review each sprint. Your engineers write the code and keep the knowledge.

    • Sprint-by-sprint guidance and reviews
    • Knowledge transfer to your team
    • Weekly cadence, with clear ownership boundaries
    Fractional CDO and advisory

Why we build rather than configure

Three things a bespoke system does that a subscription cannot. Each one is measured on a client system and written up in full.

What we build on

We work in the modern data and AI stack rather than a single vendor's version of it. AWS is the one formal partnership we hold; Google Cloud is our preferred platform and everything else here is a tool we use daily.

Cloud

  • AWS Partner
  • Google Cloud
  • On-premise and private VPC

LLM and agent engineering

  • Anthropic
  • LangChain
  • LangGraph
  • LlamaIndex

Modelling and training

  • PyTorch
  • TensorFlow
  • TFX

Data platform

  • dbt Labs
  • Fivetran
  • Apache Airflow

Analytics

  • Custom analytics and audit tools

Naming a tool here means we have shipped production systems with it, not that we resell it. AWS Partner is a formal status; the rest are the things we reach for, and we will use yours where you already have one.

We go deep in every sector. Travel, for example.

For travel operators, that means itinerary drafting, enquiry triage, demand forecasting, and marketing attribution, with your team owning the models: see what that looks like in travel, the rest of our services, or the work itself. We bring the same depth to fintech, HR tech, and beyond.

Technical Expertise You Can Trust

Our bespoke solutions are backed by technical depth documented in published books by our director

Before you book the call

Six questions we are asked before a first call, answered the way we answer them on it.

What does a proof of concept cost?

A fixed price for a scope we agree together, quoted in writing within a week of the first call. The scope decides the number, which is why there is no price list here: email us or book a call. You pay per two-week milestone and can stop at any of them.

How long before we see something working?

A written scope within a week. A working proof of concept by the end of week four, with a milestone every week on the way. After the go decision, two-week milestones, each with a demo you can use.

What if it turns out not to work?

Then you find out at week four instead of month eight. The no-go report says why, what would have to change, and what to do instead. It has happened, and the client kept the report and the data work.

Our last consultants left and nobody could run what they built. How is this different?

Two ways to work, and both leave the knowledge with you. Your engineers build it with us reviewing every sprint, or we build it and hand over the code, the documentation and the retraining procedure, with training for the people who will run it. The person you speak to on the first call is the person who writes the code.

Why not a large consultancy, or an offshore team?

You speak to the people who write the code: a small team led by a director with a PhD and published books on generative AI, MLOps and time series. There is no account layer, no bench of juniors, and no handover between the person who sold it and the person who builds it.

Do you work outside London?

Yes. We are in London and work remotely across the UK and Europe. Where data protection rules mean the data cannot leave the jurisdiction, we deploy on a private cloud or on infrastructure you host, in the country you choose.

Bring the project that stalled

A 30-minute call with Ben Auffarth. You describe the problem; we tell you whether we can help, and say so plainly when we cannot.
