What we do

From strategy to production, we work end-to-end across the modern stack.

Pragmatic software engineering, architecture reviews and platform modernisation that move you off legacy and onto solid ground.

  • Software & API development
  • Architecture & technical strategy
  • Legacy modernisation

Cloud

Secure, cost-aware cloud foundations on AWS, Azure and GCP — with the automation and observability to run them with confidence.

  • Cloud migration & landing zones
  • DevOps, IaC & CI/CD
  • Cost & reliability engineering

Data

Modern data platforms, pipelines and analytics that give your teams trustworthy answers — and a foundation for AI.

  • Data platforms & warehousing
  • Pipelines & engineering
  • Analytics, BI & ML enablement

How we work

Outcomes first. Hype never.

A straightforward way of working that keeps delivery honest and momentum high.

  1. 01

    Discover

    We learn your goals, constraints and the realities of your existing systems.

  2. 02

    Design

    We shape a clear, pragmatic plan with the architecture to back it up.

  3. 03

    Deliver

    We build in small, shippable increments — with you in the loop throughout.

  4. 04

    Embed

    We hand over with documentation and upskilling so your team owns it.

Who we are

A senior team that ships.

Leatham is a boutique technology, cloud and data consultancy. We're engineers and architects who have spent careers building and running systems in production — not just advising on them.

We deliberately stay small so the people you meet are the people who do the work. That means fewer layers, faster decisions, and a partner who genuinely cares whether the thing actually works.

Work with us
  • Senior by default. No bait-and-switch staffing.
  • Vendor-neutral. The right tool, not the trendy one.
  • Plain English. No jargon between you and the decision.
  • Built to hand over. We design ourselves out of a job.

Let's build something that lasts.
