AI Product & MVP Development in Lisbon
The best AI Product & MVP Development in Lisbon, 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.
Lisbon has grown into a base for international founders, remote teams and the engineering centres of European companies, with Web Summit, the city's Unicorn Factory and a strong engineering school feeding the scene. Many companies here are young and distributed, with founders who relocated from elsewhere in Europe or beyond, and they buy pragmatically: small, fixed engagements that prove themselves before anything larger.
Founders who move to Lisbon often arrive with an idea and a deadline. The build ships a production product in weeks, with GDPR handled and code your future Lisbon hires can maintain.
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 EUR, payable by Wise or bank transfer.

Who builds here
Fractional CTO Services
Lisbon is full of relocated founders running distributed teams who have reached the point where no one owns the technical direction. A fractional CTO gives them that, part time and month to month, which suits companies still proving their model.
What Lisbon 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
GDPR is supervised in Portugal by the CNPD (Comissão Nacional de Proteção de Dados). NIS2 is transposed by Decree-Law 125/2025, the new cybersecurity legal regime, in force since 3 April 2026, with the National Cybersecurity Centre (CNCS) at its centre. Portugal has named ANACOM as its lead authority for the EU AI Act, working with the CNPD, Banco de Portugal and the CMVM in their own fields, and has not passed a separate national AI law. DORA has applied to financial entities since January 2025. EU AI Act transparency duties apply from August 2026, and most high-risk obligations are now due from December 2027.
Contracting and payment
You contract with an individual consultant based in India. Invoices in EUR or USD, paid by Wise or bank transfer. Your accountant handles an overseas supplier in the usual way, and any documentation they need is provided before access is granted.
Working hours
Your whole morning overlaps with my afternoon, so calls fit before lunch and replies come the same day.
How do the hours work with Lisbon?
Your whole morning overlaps with my afternoon, so calls fit before lunch in Lisbon and replies come the same day. Work done in the late afternoon is written up so it is waiting for you the next morning.
Can our data stay in Portugal or the EU?
Yes. We deploy into an EU region of your own cloud account, or onto servers you control in Portugal, and the model, serving layer and logs stay there. Nothing is routed through an external AI provider unless you choose that.
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.
