AI Product & MVP Development in the UK
A real, production-grade build you can put in front of users or investors. Frontend, backend, mobile, the agentic AI underneath, and the cloud or private infrastructure it runs on, as one engagement rather than four vendors.
UK buyers tend to arrive with a clearer specification and a tighter budget than their US counterparts, and they ask harder questions about who is actually doing the work. That suits an arrangement where one named engineer does all of it and says so. London day rates for senior AI engineering make an in-house-quality build uneconomic below a certain deal size, and that gap is what this fills.
What you get
- Full-stack build on Next.js, Node or Python, with a database and API design that survives past the MVP
- AI where it earns its place: LLM features, retrieval over your own documents, agent flows that call real tools, voice
- Auth, payments, analytics and an admin surface, not a demo that breaks on the second user
- Deployment across AWS, GCP or Azure, or private and on-premise hosting where the data demands it
- Clean, documented code on your own infrastructure, written to make us replaceable on purpose
Final pricing depends on scope, features and complexity, so we settle it on a call before any work starts.
Invoiced in USD or GBP, payable by Wise or bank transfer.
Request a callback
You speak to the engineer who does the work. No sales rep, no deck.
Get it built at $0.
That is not a discount. It is when you pay. The work is split into checkpoints with acceptance criteria written down before anything starts, and each checkpoint is invoiced only after you have seen it and accepted it. No deposit.
- $0 to start
- You hold every dollar until a checkpoint is delivered and you accept it. No approval, no invoice.
- Fixed cost, unlimited features
- Or hire the team outright: one fixed monthly cost, unlimited feature development, any stack.
- The engineer takes your call
- The person on your first call is the one who architects and writes it. No account managers, no bench time.
A US agency quotes $50,000 to $150,000 for the same build and asks for 40 to 50% of it before a line is written. Account managers, project managers, sales commission and bench time. None of it appears in your product.
Three stages, nothing hidden.
Twenty-minute call
You talk to the engineer who will build it, not a sales rep. We scope the problem and you get told plainly if this is the wrong fit.
Fixed proposal in 48 hours
Fixed price, fixed timeline, defined deliverables, in writing. No hourly billing surprises and no open-ended scope.
Weekly demos until it ships
Working software every week, direct access over Slack or WhatsApp, and documentation handed over at the end.
What actually applies here.
Regulation and data
In practice the constraint is commercial before it is legal. UK buyers, especially in health and financial services, ask where data is processed and who can see it, and they ask it in the first procurement conversation rather than the last. Running the model inside your own estate turns that from a question you have to argue about into one you answer in a sentence.
Contracting and payment
You contract with an individual consultant based in India, not a UK company. Invoices can be issued in GBP or USD and paid by Wise or bank transfer. Your accountant will treat an overseas supplier in the usual way; any paperwork they need is provided before work begins.
Working hours
Full UK working-day overlap. Calls at whatever hour suits your team, and no waiting a day for an answer.
Can everything stay inside the UK?
Yes. The deployment runs on your own hardware or in a UK region of your own cloud account, so data does not leave the country. That is usually the quickest way to close out a procurement question about overseas processing.
What does the working day look like?
Full overlap with UK hours. Calls whenever suits you, same-day answers, and no overnight round trip on questions that should take ten minutes.
Who actually does the work?
One named engineer, end to end, with nothing delegated to a team you have not met. That is the point of the arrangement rather than a limitation of it.
Is three days realistic?
For a working, demoable version of a core idea, yes, and that is what the three-day build is. A full production system with billing, admin and hardening takes weeks, not days. We will tell you which one your situation actually needs.
Do we own the code?
Entirely. It ships into your repository on your own cloud accounts, documented so your team or your next hire can pick it up without us.
Can you also host the AI model privately?
Yes, and as part of the same engagement. If compliance means inference cannot leave your network, the serving layer and the application are built together rather than handed between vendors.
