AI Product & MVP Development in Madrid
The best AI Product & MVP Development in Madrid, 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.
Madrid is Spain's corporate and financial centre, home to the headquarters of large banks, telecom operators, utilities, construction and insurance groups, as well as the central government. Much software is bought through large integrators and consultancies, and mid-sized companies increasingly want specialists who can deliver a defined piece of AI or data work underneath those relationships.
Madrid founders often sell to large Spanish corporates, whose procurement asks about security and data handling early. The build ships a product with those answers ready: access controls, logging and data processing documentation.
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
AI Data Analyst
Madrid's large companies and their mid-sized suppliers run on databases that finance and operations teams query constantly through a few overloaded analysts. A read-only analyst inside their own cloud gives them answers quickly without new data leaving their control.
What Madrid 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 enforced in Spain by the AEPD (Agencia Española de Protección de Datos), an active enforcer, alongside the national LOPDGDD. Spain created AESIA, the Spanish Agency for the Supervision of Artificial Intelligence, as its lead AI Act authority, and a draft organic law on the good use and governance of AI was before the Cortes in 2026 and should be checked for its final form. Spain had not yet completed NIS2 transposition at the time of writing, so the earlier Royal Decree-law 12/2018 still applies, and suppliers to the public sector work to the Esquema Nacional de Seguridad. DORA has applied to banks and insurers since January 2025, and most EU AI Act high-risk duties 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
Four or more hours of daily overlap across your morning, Central European time, with same-day replies on working days.
Can you work as a subcontractor to our integrator?
Yes. That is a common arrangement in Madrid. The integrator holds the contract and the client relationship, and we deliver the AI or data component underneath, with acceptance criteria agreed in writing and code delivered into the client's repositories.
What does AESIA mean for an AI project in Spain?
AESIA supervises the EU AI Act in Spain, and the national AI law that will set its full powers was still going through parliament. We classify each system against the AI Act and document its use, so you are ready whichever final form the law takes.
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.
