We're a senior engineering team for growing businesses. We build enterprise-grade custom software, rescue companies from systems that hold them back, and help you put AI to work where it genuinely makes a difference, from first assessment to production.
Most of the businesses we meet are held back by one of these, and often more than one.
A slow, fragile, or unsupported system, or a project a previous vendor never finished, that your team works around every day.
Operations held together with spreadsheets, email, and double entry that no longer scale and depend on a few key people.
Hundreds of tools and a new model every week, but no clear view of where AI would actually make a difference in your business.
An AI pilot impressed everyone in a meeting, then never made it into daily work because nobody wired it into your systems.
We fix the foundations and apply AI where it pays off, as one senior team that's accountable for the result.
Most of our clients need both: solid software foundations, and AI applied where it genuinely makes a difference. Because one team does both, nothing gets lost in the hand-off.
Since 2016 we've engineered the platforms established businesses run on, and rebuilt the ones that let them down.

Failed projects, unsupported legacy systems, and software nobody wants to touch are more common than you'd think. We don't patch someone else's codebase. We rebuild it better, without stopping the business, and stay with you for the long term.
A senior engineer reviews your current system, data, and integrations to understand what the business actually needs from it.
We build a new platform in parallel with the old one, on a clean, modern foundation, so daily operations carry on while the replacement takes shape.
Data is migrated and verified, users are trained, and we switch over in planned stages, not with a risky big bang.
We keep it secure, fast, and evolving as your business grows. On average, clients work with us for more than three years.
The biggest AI wins are rarely flashy. They're the repetitive, document-heavy, data-heavy jobs your team does every day, often inside the software we build. Here's where we've already delivered results.
Pull data out of invoices, receipts, claims, contracts, and forms automatically, check it, and push it straight into your systems.

Ask questions of your operational data in plain English and get answers, trends, and alerts without waiting for someone to build a report.
Answers come only from your own data and documents, with sources. No guesswork.
Whether it's new software, a rebuild, or AI, every engagement follows the same path. Each step has a fixed scope and a clear deliverable, and you decide whether to go further.
30 minutes · Free
Talk through your operations, systems, and goals with a senior engineer. You'll leave with concrete next steps, whether or not we work together.
1–2 weeks
We map your workflows and systems, find where time and money go, and give you a prioritised plan: what to build, fix, or automate with AI, with cost and risk for each.
2–4 weeks
A working AI proof of concept on your real data, or a first working slice of new software, so you see real results before committing to the full build.
Weeks, not years
We engineer the production system, integrate it with your tools, migrate your data, and ship in increments you can see every week.
Ongoing
We keep it secure, monitored, and improving under an SLA, and keep finding the next win on your roadmap.
Software and AI systems we've designed, built, and run for clients.
The challenge
The business needed one system to take orders, dispatch drivers, and keep customers informed.
What we built
An ordering and logistics platform with customer apps, driver management tools, and an automated dispatch and routing engine.
The challenge
eCommerce teams need accurate, channel-ready listings for huge catalogues. Writing and checking them by hand can't keep up.
What we built
An AI content engine, delivered as a secure API, that generates and enriches product copy and attributes.
The challenge
A returns operation with hundreds of field users needed accurate, real-time data on multi-million dollar inventory.
What we built
An end-to-end reverse logistics platform with a custom workflow engine and offline-capable mobile apps.
The challenge
Claims were checked against contracts and policies manually. It was slow, and revenue slipped through the gaps.
What we built
Document intelligence that parses claims, compares them with contract terms, and flags exceptions for a person to decide.

We work best with established, owner-led and mid-sized businesses where the people who feel the problem can make the decision, usually in operations-heavy industries.
Founders, MDs, COOs, and operations leads who can say yes without six months of committees.
Teams losing hours to spreadsheets, manual processes, and software that no longer fits the business.
Information spread across spreadsheets, inboxes, and systems that don't talk to each other.
Logistics, manufacturing, distribution, retail and eCommerce, financial and professional services, healthcare, and more.
Explore industriesProbably not a fit: idea-stage startups looking for an MVP, or organisations that need a lengthy procurement process before a first conversation.
Both, and most of our clients need both. We're a senior engineering team that has built enterprise-grade custom software since 2016, and we apply the same engineering discipline to AI. That means the AI we recommend actually gets built into your systems, rather than stopping at a slide deck.
Yes, by rebuilding it better. We don't take over or patch existing codebases, because inheriting someone else's problems rarely ends well for the client.
Instead, we audit what you have, rebuild it properly alongside your current system, and migrate in planned stages so the business keeps running. Then we stay on as your long-term engineering partner.
You can, and for prototypes, experiments, and testing an idea it's genuinely great. The hard part of business software isn't getting something that works in a demo. It's making sure it keeps working, for everyone, every day. That's where our expertise comes in:
The best of both: vibe code a prototype to explore the idea, then use it as a living spec for us to engineer the real thing properly.
Yes. Most of our clients aren't tech companies. The best AI opportunities are usually in everyday work such as documents, data entry, email, and reporting. If your team does repetitive work with information, there's almost certainly something worth automating, and the free strategy call is designed to find it.
It depends on scope, so we don't publish prices. What we can promise is that you'll know the number before we start: every stage has a fixed scope, builds come with a capped budget, and we model ongoing AI running costs upfront so there are no surprise bills.
Assessments take one to two weeks and proofs of concept two to four.
We ship in increments, so you see progress every week.
A senior engineer, not a salesperson, gets back to you to arrange a free 30-minute strategy call. We talk through your operations, systems, and goals, and you leave with practical next steps.
If there's a fit, we'll suggest a short, fixed-scope assessment so you know exactly what you'd get, and what it would cost, before committing to anything bigger.
You do. You own your application, its data, and the IP of the software we build for you.
We keep ownership of our own reusable internal libraries and tooling, and license them to you as part of your system. That way you benefit from years of proven engineering without paying to reinvent it.
Yes. We host in the EU or your region, build security in from day one (SSO, role-based access, audit logs), and use enterprise AI services with zero-retention settings so your data is never used to train public models. We're used to signing NDAs and DPAs and completing security questionnaires.
Yes, integration is one of our core strengths. We connect to your ERP, CRM, finance, document, and email systems, and when off-the-shelf tools can't do the job, we build the custom software to fill the gap.
Most clients keep us on as their long-term engineering and AI partner. On average, clients work with us for more than three years, across everything from new platforms and rebuilds to integrations and AI.
