Build · All three scales

Custom software, fit-built and owned outright.

Custom software development for businesses that have outgrown near-fit SaaS. We build the system your process actually needs with a small senior team, ship working software every two weeks and hand over the code, the cloud and the documentation.

Why this exists

When the software doesn't fit, your team pays the difference.

Off-the-shelf software is built for the average customer. When your business isn't average, the difference shows up as workarounds, spreadsheets, customisation quotes and per-seat fees for tools nobody fully uses.

Our custom software development starts with that misfit. We map where the process and the software diverge, price it and build only what the process actually needs. Then we hand it over: code in your repositories, infrastructure in your cloud, no licence fees and no dependency on us.

Small senior teams working with AI agents are why this is viable now. What used to need a large team and two years ships in months, at a cost that competes with another round of SaaS customisation.

The same process drawn twice. On the left a rectangular product leaves gaps that become workarounds. On the right the software is shaped exactly to the work.

Problems we solve

When custom software is the right call. And when it isn't.

01

The customisation quote rivals building

The vendor's quote to make the platform fit costs as much as a system you would own.

02

The workaround has become the process

A spreadsheet or side tool carries the work the main system can't, and it is now business-critical.

03

Per-seat fees outgrow the value

Licence costs scale with headcount while the features you use stay the same.

04

No vendor fits your market

Local payment, tax, compliance or operating rules that global software doesn't model.

05

Your roadmap isn't the vendor's

You wait on someone else's release cycle for features your business needs now.

Deliverables

What you get. All of it yours.

Fit Assessment

A two-week written diagnosis of the misfit and the right build scale, yours whether or not we proceed.

Design package

Technical design and architecture you can review, approve or take to another team.

Working software every sprint

Two-week sprints with a demo each time. No big-bang reveal.

Integrations

Connected to the ERP, CRM, payment, logistics and data systems you keep.

Full ownership

Code in your repositories and infrastructure in your cloud. No licence or per-user fees.

Handover kit

Documentation, test suites, runbooks and knowledge transfer, plus an optional 3–6 month support tail.

How it runs

Four phases. No big-bang reveal.

Phase 1 · 2 weeks

Fit Assessment

Discovery, scoping and proposal-level architecture. A written diagnosis whether or not we proceed.

Phase 2 · 2–4 weeks

Design & Architecture

Detailed technical design: a package you can review, approve or take elsewhere.

Phase 3 · scale-dependent

Build

Small senior AI-augmented team. Two-week sprints. Working software shipping every sprint.

Phase 4 · 2–4 weeks

Handover

Code to your repositories, infrastructure to your cloud, documentation and knowledge transfer.

Who this is for

Operators with a decision on the desk.

SME and mid-market operators

Your business has outgrown near-fit tools and the next customisation quote is the trigger.

Founders building on software

You need a senior team to build the platform your company will run on, and to own it fully.

Operations-heavy businesses

Retail, real estate, recruitment, logistics and services, where the operation is the advantage.

How we compare

The same question, three ways to answer it.

Insightive Off-the-shelf SaaS Outsourced dev agency
Fit to your process Built around it You adapt to the product Built to the spec you write
Ownership Code, data and infrastructure are yours Rented, per seat Varies, sometimes with lock-in
Team Small, senior, AI-augmented The vendor's roadmap team Often large and junior-heavy
Working software Every two weeks after design Fast to start, slow to fit Often months before a demo
Long-term cost No licence fees after handover Rises with headcount Ongoing dependency for changes

Common questions

What is custom software development?

Software designed and built for one business's process rather than bought off the shelf. You own it, and it changes when your business does.

How much does custom software development cost?

It depends on scale. A Process Build runs 2–8 weeks with 2–3 senior engineers; a Platform Build runs 6–18 months with 4–8. The Fit Assessment gives you a firm estimate before you commit.

How long does it take?

Two to eight weeks for one workflow, two to six months for a system and six to eighteen months for a platform.

Who owns the code?

You do. Code, data, infrastructure and documentation are handed over in full, with no licence fees and no dependency on us.

When is off-the-shelf software the better choice?

When the process is standard and the software fits it. We say so in the Fit Assessment and point you to the right product.

Do you use AI in development?

Yes. Every engineer works with AI agents daily: the agents handle the volume, the engineers handle the judgement. That is where the time savings come from.
