01 — The real problem

Most software projects don't fail. They stall.

Nine months in, the demo works and nothing is in production. If any of these sound like your last quarter, that's the problem we exist to remove.

Book a Discovery Call →
An AI prototype that demos beautifully and breaks the moment real client documents hit it.
A cloud bill climbing every month with nobody able to say which query is causing it.
A team still doing by hand the work you already paid to automate.
Integrations that need a person watching them, and break on someone else's release.
You want one senior team that owns the architecture, ships it, and stays accountable for it in production.
02 — The cost of manual work

Boring work is the most expensive thing you own.

Copy-pasting between tools. Re-keying invoices, tickets, listings, reports. It is quiet, it is every day, and it bills you twice — once in salary, once in the work that never got done. Worse, it slows you down where it costs most: the business goes to whoever replies first. We build a system around that process so the hours come back and the freed capacity turns into revenue.

03 — What we do for you

Four things, done for you, end to end.

Book a Discovery Call →

Full-Stack Development

You get a product real customers can pay for — auth, billing, admin panel, the lot. Multi-tenant and built to hold up under real load, not to look good in a demo. React, Next.js, Node.js, PostgreSQL.

Agentic AI Development

Autonomous agents and RAG systems that do the work, not just answer questions. Retrieval you can cite, evals you can trust, and a human-review path anywhere the stakes are high.

Book a Discovery Call →

Business Automation

The repetitive work your team still does by hand, running itself. Document pipelines, n8n/Make workflows and integrations that give hours a week back — and stop the errors that come with copy-paste.

Book a Discovery Call →

AI Audit

A fixed-fee look at how your business actually runs: where AI and automation pay back, what they would save in hours and cost, and what to ignore. You leave with a prioritised roadmap and the numbers behind it — build it with us or without us.

05 — How it works

Three steps. Almost none of your time.

Book a Discovery Call →
1

Discovery call

You tell us the outcome you need. We tell you straight whether we're the right team, what it costs, and how long it takes. You leave with an architecture plan you keep either way.

2

We build it for you

A senior team in your repo shipping weekly demos you can click. One 30-minute check-in a week is all we need from you — no managing, no briefing, no hiring.

3

Launch & scale

We ship to production with tests, CI/CD and monitoring in place, hand over documented code you own, and stay on for support and scaling if you want us.

06 — Engagement models

Two ways in. Neither locks you into the other.

For building Monthly · scales with you

Embedded build team

We work in your Slack, your standups and your repo, accountable to your outcome rather than a frozen spec — so the roadmap adapts as you learn instead of triggering a change order. Resourcing scales up or down as priorities shift.

Weekly demo you can click, shipped in increments
Milestones approved by you before they are invoiced
Your repo, your infrastructure, your IP from commit one
Stay through launch and scaling, or hand over documented

For clarity Time-boxed · fixed fee

Fixed-fee AI audit

A defined process with a defined deliverable and no open-ended commitment. We assess your workflows, data and stack — including the parts you may not want to hear — and hand back a path you can act on with us or without us.

07 — Our commitments

Either model, same commitments: no lock-in, no surprises, code you own.

Audits are fixed-fee with a defined deliverable — you know the cost before you start.
Embedded work is transparent monthly, with milestones you approve before the next one starts.
Your repo, your infrastructure, your IP — from the first commit.
Stop, pause or scale the team month to month — and if a milestone misses its agreed criteria, we fix it before we invoice it.

The questions you're already thinking.

Anything not covered here, ask it on the call — we answer directly, including when the answer is "we're not the right fit."

How much does a build cost?

Most engagements land between a focused automation build and a full platform. You get a fixed price against a fixed scope after the discovery call — before you commit to anything.

Can a small team really ship this fast?

That's exactly why it's fast — senior engineers, no handoff layers, architecture decided in week one. Systems we've built serve 1M+ users in production.

What if we already have an in-house team?

Then we embed. We work in your repo, your conventions, your standups — or take one isolated workstream off your team's plate. Both are normal for us.

Who owns the code and the AI models?

You do — repo, infrastructure, prompts, pipelines, documentation. No vendor lock, no license fee, nothing hostage.

Is the AI reliable enough for client-facing work?

It is when it's engineered instead of prompted: retrieval with citations, eval suites, confidence thresholds and a human-review path on anything high-stakes.

What happens after launch?

Your choice: a clean documented handover to your team, or a monthly retainer for support, cost tuning and the next roadmap items. No lock-in either way.
