The Group's own software house

We forge software that moves
the Lagan Group forward.

Lagan Foundry builds and deploys technology across the Group — better and faster than the outside market, and at least 25% cheaper than what you pay for it today. We lower your cost today and improve performance tomorrow — the saving stays in the family, and the IP stays yours.

Why we exist

The Group already spends millions on software.
Let's spend it inside.

Across the Group, a large slice of budget leaves every year for licences, custom development and websites — paid to outside suppliers at their margins, on their timescales.

Lagan Foundry turns that spend into an asset. We build the bespoke work in-house, hand the operating company a lower bill, return profit to the Group, and keep the know-how — and the code — under the Group's roof.

But the real prize isn't the software. At Trimline, TAPP's biggest impact wasn't a smaller IT bill — it was better decisions, sharper reporting, tighter project management and stronger communication: a genuinely stronger business. The lower bill is just the start — the lasting value is a business that's easier to manage, giving its leaders clear visibility and control over everything that matters.

What we really build

Every pound the Group spends on software should make the Group stronger — not somebody else's business richer.

How we deliver

However the work needs to reach your people

Three delivery strengths under one roof — so the answer fits the problem, not the other way round.

🌐

Web systems & websites

Secure, browser-based platforms and public websites your teams and customers reach from anywhere — like TAPP.

📱

Mobile apps

Apps built for the field — on ships, on sites, offline-capable — putting the right tools in your people's pockets.

🤖

AI workflows & experience

AI woven through the work — automating the routine, capturing the knowledge and surfacing the insight that moves decisions.

What we build

Capabilities, battle-tested

Every one of these already runs live in TAPP, the system that operates Trimline end to end. We don't prototype on you — we deploy what's proven.

How it works

Simple, honest, and in your favour.

No lock-in, no black box. You stay in control of price and you own everything we build.

1

You get the market price first

Take the job to outside suppliers and get your quotes, exactly as you would today. Nothing to lose.

2

We beat it by at least 25%

Lagan Foundry commits to undercut the best external quote by 25% or more — in writing.

3

The Group keeps the upside

You save on the bill, and the Group shares in the Foundry's profit — so the total benefit is around half of what you spend today.

4

You own it, and we prove it

All IP belongs to the Group, and we're happy to be benchmarked against the market at any time.

Bank the savings. Dodge the Software Companies.

Pick your leader and roll out software across the Group. Every module you ship banks a real-world style saving — but the Software Companies (external vendors chasing your spend) want it back. How much can you save in one year?

The proof

TAPP: one company, run entirely on software we built.

Trimline — a marine interior outfitter delivering projects on ships around the world — runs stock, purchasing, projects, on-site operations and HR on a single system we designed and built: TAPP.

It's not a demo or a pilot. It's a whole business, operating on our code, every day. That's the engine we want to put to work for the rest of the Group.

"Unless the Group embraces this now, we'll spend the next few years catching up to where we could already be. The time to move is now."

Sustainability

Growing the business, growing the forest.

Technology should give something back. For every £100 the Group spends with Lagan Foundry, we plant £5 of trees — building the Lagan Forest as the business grows.

£5 in every £100
We plant £5 of trees for every £100 you spend on development — automatically, on every project.

Growing together
The more the Group builds with us, the more the forest grows — progress you can measure, and see.
