Software Development Company in Madrid
The best Software Development Company in Madrid, at the best available price.
You need engineering capacity that does not come with account managers, project managers and three juniors learning on your budget. One fixed monthly cost, senior people, any stack, and the person who takes your call is the person who writes the code.
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 companies often depend on large consultancies for capacity. A dedicated senior engineer is a smaller, direct alternative for a defined part of the roadmap, working in your repository and alongside your existing supplier.
What you get
- Senior engineers only, on a fixed monthly cost with unlimited feature development rather than hourly billing
- Full stack: web, mobile, backend, data and the cloud infrastructure underneath it
- Your repositories, your cloud accounts, your credentials, throughout the engagement and after it
- Works alongside an existing integrator or in-house team rather than requiring you to displace either
- Month to month, because a team you cannot leave is just an expensive hire
Nothing payable upfront on project work: you pay per checkpoint, after you have seen it and accepted it. Retainers are month to month with no long lock-in. Scope and price are settled on a call.
Invoiced in USD or EUR, payable by Wise or bank transfer.

You speak to the engineer who does the work. No sales rep, no deck.
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
We work out what capacity you actually need. Plenty of teams need one strong engineer for six weeks rather than an ongoing arrangement, and you will be told if that is your situation.
First month, scoped
A defined block of work with acceptance criteria written down before it starts, so you can judge the arrangement on delivered software rather than on a pitch.
Ongoing, month to month
A fixed monthly cost, direct access over Slack or WhatsApp, and no lock-in. You leave with the code, the documentation and the infrastructure, all of it already yours.
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.
Do you have a local office here?
No. You contract with an individual consultant based in India, which is exactly why the cost is what it is. If your procurement requires a locally registered supplier, we work as a subcontractor to your local partner instead.
How is this different from hiring an agency?
An agency bills you for a team and staffs it with whoever is free. Here there is no bench, no account manager and no sales commission in the price, and the engineer on your first call is the one writing the code. The trade-off is honest: you get depth from one senior person rather than breadth from five.
Can you work with our existing team?
Yes, and that is the usual arrangement. We take the parts your team does not have depth in, in your repositories and against your standards, rather than carving out a separate project nobody else can maintain.
