What We Do

Built at the intersection
of theory and practice.

We work with organisations that need AI done properly — from initial feasibility through to deployed, monitored systems in production.

Engineering
Machine Learning Engineering
End-to-end model development — from exploratory analysis and feature engineering through to training, evaluation, and serving at scale.
Engineering
Data Infrastructure
Robust pipelines, data warehouses, and feature stores that make your data actually usable — designed for reliability and observability from the start.
Engineering
Large Language Model Integration
Production-grade LLM systems — RAG architectures, fine-tuning, prompt engineering, evaluation frameworks, and responsible deployment practices.
AI Adoption
AI Adoption
From first steps to organisation-wide transformation. We help businesses make AI a genuine part of how they operate — healthchecks, roadmaps, private LLM deployments, governance frameworks, and ISO 42001 readiness.
AI Adoption
Technical Strategy & Advisory
Independent, honest guidance on AI investment decisions, build-vs-buy assessments, team structure, and how to evaluate vendor claims with rigour — without an agenda.
AI Adoption
Workshops & Capability Building
Bespoke training for leadership and technical teams — from understanding what AI can and can't do, to hands-on sessions with real tooling and your own data.
How We Work

Our Approach

We believe the best AI work starts with understanding the problem deeply — not reaching for tools before the question is clear.

01
Understand the problem, not just the brief
We invest time upfront in understanding your data, your constraints, and the decision you're actually trying to support — before writing a line of code.
02
Baseline before you optimise
Simple, interpretable models evaluated against strong baselines. We don't add complexity until the data demands it — and we tell you when it doesn't.
03
Production-readiness from day one
Monitoring, versioning, and rollback baked in from the start — not bolted on at the end. A model that can't be maintained is a liability.
04
Transfer knowledge, not just deliverables
We work alongside your team, document our reasoning, and ensure the people who inherit our work understand it fully.

About

Built by engineers, for engineers.

Gradient Descent Ltd is a specialist AI consultancy, founded to bring rigorous, engineering-led practice to organisations navigating the complexity of modern machine learning.

We take on engagements where technical depth matters — where the difference between a good outcome and an expensive mistake is having people who understand the mathematics, not just the marketing.
