Run Your Business Like a £50m Contractor.
For £2,000.

You've seen the firms that always seem to have it together.

Their tender submissions are crisp. Their programmes are professional. Their payment applications land on time, every time. They've got a commercial manager tracking margins, a planner updating the programme, a H&S advisor producing site-specific RAMS, and a document controller who makes sure nothing falls through the cracks.

You've got yourself. Doing all of it. Usually after the kids are in bed.

Here's what those firms have that you don't — and it's not more people. It's systems.

What you're about to read is a straightforward explanation of how 750 UK contractors are going to get access to that same back-office infrastructure — at a fraction of the cost of a single hire. And why the window to get in at the founding member price is about to close.

If you're too big for spreadsheets and too small for enterprise software — this was built for you.

Let's talk about where you actually are.

Not where you tell clients you are. Not the version you put on your PQQs. Where you actually are, right now, today.

You're the estimator, the planner, the QS, the commercial manager, the H&S advisor, the site manager, and the man who locks up on Friday. You do the work of five people and you get paid for one.

You know you need better systems. You've known for years. Every time a payment application goes in late, every time you price a tender on gut feel, every time you realise a variation was never recorded — you know.

But every time you've gone looking for the answer, you've hit the same wall.

Enterprise software that costs more than your van. Platforms with six-month implementation timescales and training courses longer than your apprentice's NVQ. American systems that don't understand CIS, can't handle domestic reverse charge VAT, and think JCT is a motorway junction. Tools that do one thing brilliantly and nothing else — so you end up with seven subscriptions and none of them talk to each other. Sales demos that look incredible, followed by a reality that doesn't match. Support teams that take a month to schedule a call. Updates that break what was working. Contract lock-in that keeps you paying for software you've stopped using.

Sound familiar?

You're not alone. This is the experience of thousands of UK contractors. The software industry has been building for firms with IT departments, implementation budgets, and training coordinators. Firms that can absorb six months of disruption while the new system beds in.

You can't absorb six minutes. You've got a site visit at 7am and three tenders due by Friday.

So the cycle continues. No time to fix the problem. No systems because there's no time. No time because there's no systems.

That's the gap nobody was building for. Until now.

And here's the bit that matters.

You've already tried to fix this. More than once. And it wasn't because the attempts were bad — it was because the tools weren't right.

You set up the shared drive. Told everyone “right, from now on everything goes in here.” Two weeks later the lads were back on WhatsApp and the shared drive had three files in it, two of them called “Copy of Copy of Final_v2.”

You spent a weekend building the mother of all spreadsheets. Colour-coded tabs. Formulas linking everything. Then someone edited a cell they shouldn't have, and the whole thing started giving you different numbers depending on which tab you looked at.

You created a risk assessment template. Told yourself you'd update it for every project. But the next job came in fast, so you swapped out the site address and hoped nobody would notice that the methodology still referenced a different scope.

You promised yourself you'd track variations properly this time. Six weeks in, you had fourteen verbal instructions, three contradicted by an architect's email, and none of them recorded anywhere except your memory.

You've tried other software. You've tried a whiteboard with Post-it notes. You've tried hiring an admin person to “sort the office out.” None of it stuck.

Not because you're not organised enough. Not because you're not good enough. You're brilliant at what you do — you can hold an entire project in your head, programme, costs, risks, every trade, every deadline. That's actually the problem. It's all in your head. And a business that lives inside one person's head doesn't scale. It doesn't take holidays. It runs exactly as fast as you can run.

Every system you've tried has failed because it needed the one thing you don't have — time to implement it, time to maintain it, time to make it stick.

The tools weren't built for someone who can't stop working long enough to set them up.

That changes now.

Built By A Builder. For Builders.

Steve McKenna

MCIOB · MD, Gemstone Contractors · Founder, Construction AI

My name's Steve. MCIOB, 30 years in the industry. I've run jobs at UBS 5 Broadgate and Westfield London. I'm the Managing Director of Gemstone Contractors, a CIOB Chartered Building Company. I price tenders. I manage programmes. I write RAMS. I chase payments. I sit in CVR meetings and explain why the margin's moved.

I had every problem you've just read about.

So I built the solution.

Construction AI is 16 integrated modules — cost management, tenders, RAMS, programmes, payment applications, variations, drawings, specifications, communications, RFIs, submittals, site diaries, H&S libraries, CPD tracking — all connected, all in one place, all powered by an AI agent who actually understands construction.

I didn't build it to sell software. I built it because I needed it. Every module exists because I hit the problem on a live project. Every workflow is designed around how UK contractors actually work — not how a software company thinks they should work.

And I built it so it works from day one. Not after six months of implementation. Not after three days of training. You sign up, you book an onboarding call, and you're running your first project within the week.

Because I know you haven't got six months. You've barely got six minutes.

30 Years. 16 Modules. One Builder.

We don't have 500 case studies. We're honest about that.

What we have is a platform stress-tested on live projects with real data. Every module built from 30 years of real-world construction workflows. And a builder behind it who stakes his professional reputation — MCIOB, Managing Director of a CIOB Chartered Building Company — on every feature.

Here's what that means for you as a founding member: your feedback doesn't go into a suggestions box. It goes directly to the person who built it. Your problems become the next features. You're not a customer number — you're shaping the platform.

That's an opportunity most software never offers. And it's only available to the first 750.
