AI Data Analyst in Lisbon
The best AI Data Analyst in Lisbon, 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.
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.
Tourism, property and marketplace businesses in Lisbon track bookings, listings and payments across several systems. An analyst on a read-only replica answers questions in plain English or Portuguese, with the SQL shown.
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
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.

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 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.
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 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.
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.

An AI data analyst on your own read-only replica. Natural language to SQL that cannot query a table it has not read.
