AI Product & MVP Development in London
The best AI Product & MVP Development in London, at the best available price.
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.
London is Europe's largest technology and finance hub, with fintech, AI labs, insurers and banks concentrated in one city. Buyers are sophisticated and well funded, and almost every serious one asks early where data is processed and how AI decisions can be explained.
London founders raise against strong competition. The build gets a real product in front of users quickly, with UK GDPR handled properly from the first version.
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.

Who builds here
AI Development Company
London has more demand for AI product work than almost anywhere in Europe, and most of it has to hold up in front of regulated customers, which is the kind of AI engineering we do.
What London companies build with us
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
UK GDPR and the Data Protection Act 2018 govern personal data, and the Data (Use and Access) Act 2025 relaxes some rules on automated decision-making while keeping safeguards such as the right to human review of significant decisions. Financial firms answer to the FCA, whose Consumer Duty and operational resilience rules shape what they can outsource and how AI outcomes are monitored. The UK has no single AI statute; regulators apply their existing rules to AI.
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 data stay in the UK?
Yes. We deploy into UK regions of your own cloud account, and models can run there as well, so personal data stays in the UK.
Can you work with FCA-regulated firms?
Yes. That means following your outsourcing and operational resilience requirements, keeping audit trails and making sure AI outcomes can be monitored and explained, all documented for your compliance team.
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.
MVP Development
A working MVP in as little as 3 days, from $1,000. Production-grade, not a throwaway prototype.
