ML we build

Predictive models and forecasting

Demand, churn, lifetime value and risk over your historical data, with the validation to trust the numbers.

Recommender systems

Ranking and next-best-action models for products, content and operations.

Anomaly and fraud modelling

Transaction and behavioural models with a feature store and real-time scoring. The applied fraud product lives on AI development; here we build and tune the models behind it.

Credit risk and scoring

Underwriting and risk models built to be validated, monitored and explained.

Route and operations optimisation

Models that cut travel time and raise visits per day for field and logistics operations.

MLOps

Deployment, monitoring, drift detection, retraining and a model registry, so a model survives contact with production.

Feature engineering and pipelines

The data plumbing that decides model quality - built once, owned by your team.

How we work

How we deliver ML development?

The same delivery discipline on every engagement - from the first map to a handover your team runs.

01
Data audit

We check the data you have, its quality and its governance, because a small early investment there saves a large later one.

02
Feature pipeline

We build the feature engineering and the training data so results are reproducible.

03
Train and validate

We train, validate and challenge the model against the bar your use case needs, with the evidence written down.

04
Deploy and operate

Deployed in your cloud with drift detection, a retraining cadence and monitoring on the model's own targets, handed to your team.

In practice

What shapes the work

Models that earn their place in production

A model is only worth building if a decision changes because of it. We start from that decision, the data behind it and the bar it has to clear, then build the simplest model that clears the bar and the pipeline to keep it there.

In a regulated setting the modelling and the governance are one job. Where the data came from, how a prediction is logged, how the model is validated and challenged - these are designed in, not added when an auditor asks. Where the question is really analysis rather than a model, that is data analytics.

Frequently asked questions
How is ML development different from AI development?

ML development is the modelling work: training custom models on your data, building predictive and recommender systems, and running the operations that keep them accurate in production. AI development wraps a capability into a product, covering agents, vision, natural language, decisioning and the integration around them. Most regulated engagements use both, and we will tell you which one your case needs rather than sell the larger of the two.

Do you build the model only, or run it in production as well?

Both. Deployment, monitoring, drift detection, retraining and a model registry are part of the default handover, because a model that is accurate at launch and unwatched is wrong within months while nobody notices. Where that operations layer is the work you actually need, on its own or on models your team already runs, it is scoped as MLOps development.

What kinds of models do you build?

Predictive and forecasting models, recommender systems, anomaly and fraud models, credit risk and scoring models, and optimisation models for operations. The class is chosen against the decision you need to change: a well specified statistical forecast frequently does the same job as deep learning at a fraction of the complexity, and we say so before the budget is committed.

Our data is messy. Can you still help?

Yes, and the data audit comes first for exactly that reason. It tells you what is usable, what is missing and what would have to be fixed before a model can be trained, from a small fixed piece of work instead of a large one. For a European institution it is also the compliance question: Article 10(3) of the EU AI Act, Regulation (EU) 2024/1689, requires the training data behind a high-risk system to be relevant, sufficiently representative and, to the best extent possible, free of errors and complete. Credit scoring is one of those high-risk uses, and the Digital Omnibus on AI, Regulation (EU) 2026/1744, moved the application date for standalone Annex III systems to 2 December 2027, which is time to fix the data rather than a reason to defer it.

How does adding machine learning to a legacy system change the timeline?

The model is rarely the long pole. Reaching the data is: an older core often has no clean API, the history sits across several systems that define the same field differently, and reconciling them is what sets the date. We scope the data access path during the audit and give you a staged plan, so the first useful model trains on a subset of sources instead of waiting for the whole estate to be tidy.

How do you know a model will hold at production volume?

We build for production from the first sprint instead of promoting a notebook later. The same feature pipeline feeds training and inference so results do not drift between the two, and load, latency and failure behaviour are tested against your real volumes before release. Every model, dataset and metric is versioned and each prediction is logged with the version that produced it, which makes a degradation traceable rather than a surprise.

Should we build machine learning capability in-house or bring in a specialist team?

An internal team can own this, and for a bank with a standing data function that is usually the right end state. A specialist shortens the parts that are easy to get wrong and expensive to retrofit: the feature pipeline, validation and challenger models, monitoring, and the governance a European supervisor will ask about. We build inside your repositories and your cloud alongside your engineers, so the capability stays with you when the engagement ends.

How do you keep models explainable and compliant?

We choose model classes and logging patterns that produce explanations by default, validate against a challenger where a regulator expects one, and design override paths so a person can intervene with the reason recorded. In the EU an automated credit decision also answers to Article 22 of the GDPR, Regulation (EU) 2016/679, which has applied throughout and did not move when the AI Act timetable did. A decision the model cannot explain is a decision you cannot ship, so explainability is designed in and not reported at the end.

Who owns the model and the pipeline at the end?

You do. Source, feature pipelines, training scripts, model artefacts and documentation are yours, running in your own cloud and handed over with a runbook. Nothing about operating or retraining the model requires us to still be there.
