Big ideas deserve exceptional engineering.

We turn complex ideas into intelligent systems, secure software, and products people can use.

From complex problems to working systems.

Three solutions of our own that you can license, and three platforms we built for clients, in use today.

Our solutions · 1 of 3

SHADOW

Malware detection from raw bytes

Solution · Malware detection · For security teams and vendors

A foundation model that learns to recognise malware directly from the raw bytes of executables.

Available to license or pilot

Our solutions · 2 of 3

CheXpert CBM

Concept bottleneck models for chest X-rays

Solution · Explainable medical imaging · For hospital research teams and medical AI developers

The model names the findings it sees in a chest X-ray before it predicts a label, so a clinician can check, and correct, its reasoning.

Available to license. Not a medical device

Different challenges. One commitment: build it properly.

Your next idea starts here.

Tell us what you're trying to build. Let's turn it into something real.

Selected work

Each project has a full case study. Pictures marked Illustration are drawings: client screens carry real people's data, so we don't publish them.

Products we license and adapt to your setup. Terms are agreed with each customer.

SHADOW

Malware detection from raw bytes

Status: Available to license or pilot

A foundation model that learns to recognise malware directly from the raw bytes of executables.

What we did
The model, its training data and the training runs.

Solution · Explainable medical imaging

For hospital research teams and medical AI developers · Since 2025

CheXpert CBM

Concept bottleneck models for chest X-rays

Status: Available to license. Not a medical device

The model names the findings it sees in a chest X-ray before it predicts a label, so a clinician can check, and correct, its reasoning.

What we did
The concept-extraction pipeline and the model training code.

Solution · Behavioural data

For teams building continuous authentication · 2025 to 2026

BEACON

Behavioural fingerprints from gameplay

442 GB, free to download

Status: Available for custom data collection

A 442 GB open dataset of keystrokes, mouse movement, network traffic and screen recordings from competitive Valorant play.

What we did
The gameplay data collection, the dataset release and the paper.

What we do

Four kinds of work, each with the projects on this site where we did it.

  • Security Engineering

    Secure design for everything we build, code review, and penetration testing of sign-in and access control.

    Seen in

  • Research & Prototypes

    Datasets, prototype models and papers, from the first experiment to publication.

    Seen in

  • AI & Automation

    Machine learning models whose predictions can be checked, and automation for repetitive work.

    Seen in

    every prediction comes with its reasons

  • Web Development

    Web portals, mobile apps and online shops, with the backend and admin tools behind them.

How a project runs

Research and security come first, then development. Dates and costs are agreed for each project.

  1. Research

    We study the problem, the data and the people involved, and write down what “done” means.

  2. Threat model

    Before any design, we list what could go wrong: who might attack it, what they would want, and what has to be protected.

  3. Secure design

    The system and the screens are planned around those risks, and we agree the scope.

  4. Build

    Development in small working pieces you can try as they arrive.

  5. Test and hand over

    Code review, tests and penetration testing before release, then deployment, documentation and maintenance if you want it.
