AI Data Analyst in Madrid
The best AI Data Analyst in Madrid, at the best available price.
Your team asks in English. The service finds the tables, writes the SQL, runs it against a read-only replica inside your own cloud, and returns the number with the query attached. It cannot touch a table whose schema it has not just read, and that is enforced in code rather than requested in a prompt. Starts at $0: you pay at checkpoints you accept.
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.
Finance, sales and operations teams in Madrid's corporate sector ask the same reporting questions every week. An analyst on a read-only replica answers them in plain English or Spanish, with the SQL shown and every question logged for audit.
What you get
- Deployed in your own cloud account against a read-only replica you create, so we never hold a credential to your database
- A signed schema check the model cannot skip: no SQL runs against a table it has not just inspected, and the tokens expire in fifteen minutes
- A grant list your data owner approves, naming the exact tables and columns the analyst may read, with everything else refused at the database
- Exposed inside Claude or ChatGPT in your organisation's workspace, behind your existing Google sign in, so nobody learns a new interface
- Every question logged with the SQL it ran, the tables it touched and whether it errored, which is what an auditor actually asks for
- Runs on a private LLM on your own hardware where data security demands it, up to fully air-gapped, so nothing at all crosses your perimeter
No payment before a checkpoint is delivered and accepted. Most builds land between $6,000 and $18,000 depending on how many databases are in scope and how much of the schema the first domain covers. Optional upkeep from $1,200 a month, and only if you want it.
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.

Stage three refuses to run unless it is handed a valid token from stage two for a table in the query. The model cannot skip the schema read, because the check is a signature in code rather than an instruction in a prompt.
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.
Fixed-fee assessment
Five business days from the day read-only access is in place. Schema inventoried, the questions your team actually asks classified as answerable or not, the grant list drafted with whoever owns data protection, and acceptance criteria written as testable statements.
Build in checkpoints
About three weeks. Deployed in your cloud account, connected to your replica and to your assistant workspace, with the semantic layer written for the first domain. Each checkpoint has criteria agreed before work starts and is invoiced only once you accept it.
Handover and closeout
A real question from your team, answered end to end, with the SQL shown and the numbers reconciled against the source rows. Runbook, recorded handoff, code and semantic layer in your repository, and all our access removed with written confirmation.
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.
We already have a BI tool. Does this replace it?
No, and it should not. Your dashboards answer the questions somebody anticipated, and they will keep doing that. This answers the ones nobody built a chart for, which is where the waiting happens. Teams that keep both end up using the dashboards for the standing numbers and the analyst for everything else.
How long before somebody can ask a real question?
Usually inside the first week of the build, on a narrow slice of the schema. The first domain being useful early is the point of doing it in checkpoints: you see it working on your own data before most of the money is committed.
What if our schema is a mess?
Most are, and it changes the shape of the work rather than ruling it out. Undocumented columns, legacy tables nobody dares delete and two spellings of the same idea are normal. The assessment tells you plainly how much of that has to be untangled first, and if the answer is that you need a data cleanup before an analyst is worth building, you will be told that instead of sold this.
