What would you build if it only took a week?
Most founders shelve their best ideas because agencies quote £15k and 3 months. I build your MVP in 5 days, fixed price, no surprises.
You have an idea. You know there's a market for it. But every agency wants months and tens of thousands before you can put anything in front of a real user. That ends here. One week. One fixed price. One working product, live and ready for customers.
15 minutes. I'll tell you what's realistic for 5 days, and you decide if it's a fit. No pitch.
The quote-negotiate-wait loop
You've got the idea. You can see it clearly — the product, the users, the revenue. So you do the responsible thing: you get quotes.
And that's where it stalls.
Wants a 12-page requirements document before they'll give you a number.
Comes back at £18,000 and "approximately 10–12 weeks."
Can't even start for another three months.
Meanwhile, the idea sits in your notes app. You keep tweaking the spec. You tell yourself you're "refining the concept." But really, you're stuck.
What you've already tried
- Hired a freelancer from Upwork. Got half a product and radio silence.
- Tried no-code tools — great until you needed something they couldn't do.
- Tried building it yourself at midnight after the kids went to bed.
- Or just kept waiting for the "right time."
The real problem
The problem isn't your idea. The problem is the model. Traditional agencies are built for big projects with big budgets on big timelines. They need 3 months because they're juggling 8 clients at once. They quote £15k because their overheads demand it.
You don't need a big project. You need to find out if anyone will actually use this thing — a fundamentally different question that needs a fundamentally different approach.
Why this works now
10+ years building web products — SaaS platforms, IoT systems, web apps serving 100k+ users. I've led engineering at startups and made the architecture decisions that determine whether a product scales or falls over.
That experience is the product. Not AI. Not templates. Not a junior following a tutorial.
Modern AI-assisted tools have changed the economics. The tedious parts — boilerplate, config, repetitive code — take minutes instead of days. That frees me to focus on architecture, UX, and the decisions that determine whether your product works or just exists.
Those tools in a junior's hands underwhelm. In the hands of someone shipping production code for a decade? That's where it gets interesting.
This isn't pushing buttons and hoping the AI gets it right. It's senior engineering at startup speed. Fixed scope. Fixed price. Five days.
No scope creep. No change requests spiralling into month 4. No "we'll need another sprint to finish the auth system."
How it works
Day 1 — Scope
I jump on a call, nail down your core idea, and define exactly what gets built. You walk away with a clear spec. No 40-page requirements document — just the stuff that matters.
Days 2–4 — Build
I build your MVP. Real code, real functionality, deployed to the web. You get daily progress updates so you can see it taking shape — and course-correct before Day 5.
Day 5 — Ship
Final polish, deployment, and handover. You get a working product you can put in front of real users that day. Not a mockup. Not a prototype. A product.
What you get
Ongoing maintenance, complex third-party integrations, native mobile apps, and large-scale systems are separate engagements — happy to quote those after your sprint. I'll tell you honestly on the scoping call if your idea needs more time.
What 5 days actually looks like
Every sprint is different, but here's what's realistic.
A niche job board
Employer dashboard, candidate profiles, search with filters, application flow, and Stripe payments for premium listings.
A client portal
Login, dashboard, document sharing, appointment booking, and automated reminders for a consultancy.
An internal sales tool
Lead tracking, pipeline stages, activity logging, and a reporting dashboard. Not Salesforce — something that fits your team.
These aren't mockups or click-through prototypes. They're working applications with real functionality, deployed and ready for users.
Fully booked March through May. One slot left for August — two open for September.

P.S. Every founder I've worked with has said the same thing: "I wish I'd done this sooner." The idea in your head is worth nothing until someone can use it. Let's find out if yours works.
