On-Premise LLM Deployment in Barcelona
The best On-Premise LLM Deployment in Barcelona, at the best available price.
You have the GPU and you have the model. What is missing is the leg in between: the model exposed as a reliable private API, reached securely from your application, returning data you can trust. That is the whole engagement.
Barcelona has a large startup community and is a common choice for the tech centres of international companies, helped by the 22@ district, Mobile World Congress and a large international workforce. Its scale-ups and tech hubs mostly buy engineering capacity and specialist skills, and English is the working language in much of the scene.
Hospitals, research institutes and health tech companies in Barcelona work with patient and research data that should not leave their control. A private model on their own servers or in an EU region of their account lets them use AI on it, and suppliers to Catalan public bodies can document it for APDCAT.
What you get
- vLLM serving tuned to your GPU: quantisation on the native kernel path, KV cache sizing, continuous batching, prefix caching
- A private network path with no public exposure, verified as a direct peer connection rather than a relay
- Schema-constrained responses plus a deterministic QA gate, so a wrong answer is rejected rather than rendered
- Documented baseline: tokens per second, time to first token, real concurrent capacity
- Infrastructure as code in your repository, a runbook, and every credential held by you
No upfront payment and no escrow required. You hold every dollar until a checkpoint is delivered and accepted, and thirty days of defect correction is included. Scope and price are set 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
Software Development Company
Barcelona's scale-ups and international tech hubs compete for the same senior engineers. A dedicated senior engineer on a fixed monthly cost adds capacity without joining that contest.
What Barcelona 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 access is in place. Your stack examined end to end, existing work classified as preserved or replaced with reasons, the connection design, and acceptance criteria written as testable statements.
Implementation in checkpoints
Around three weeks. Each checkpoint has written acceptance criteria agreed before work starts, and is invoiced only after you accept it. Appoint an independent technical reviewer if you want one.
Handover and closeout
One real request through your real application, on synthetic data, passing every QA rule. Runbook, recorded handoff, and all our access removed with written confirmation.
What actually applies here.
Regulation and data
GDPR is enforced by Spain's AEPD, and the Catalan Data Protection Authority (APDCAT) supervises Catalan public bodies and the companies providing services to them. AESIA, based in A Coruña, is Spain's AI Act supervisor, and a national AI governance law was still before parliament in 2026, so check its final form. Spain had not yet finished transposing NIS2 at the time of writing, leaving Royal Decree-law 12/2018 in place for now. DORA has applied to financial entities since January 2025. The EU AI Act has applied in stages since August 2024, with transparency duties from August 2026 and most high-risk obligations 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.
We supply Catalan public bodies. Does APDCAT apply to us?
It can, when you process personal data on behalf of a Catalan public body. We build the deployment in your own environment and document data flows and access, so you can show APDCAT or your client's data protection officer exactly where data goes.
Can you work in English with an international team?
Yes. Calls, documentation, code review and tickets are all in English, with four or more hours of daily overlap across your morning, Central European time, and same-day replies. Written updates live in your tracker so the rest of the team can follow progress without extra meetings.
We already have hardware and a model running. Is that a problem?
It is the ideal starting point. Existing work is classified during the assessment as preserved unchanged, preserved with changes, or replaced, with reasons, and nothing is replaced without your written agreement.
Can it be fully air gapped?
Yes, including model and dependency mirroring, offline updates and local evaluation, with no outbound network access at all.
Who holds the accounts?
You do, throughout. Cloud accounts are created and held by you, our access is named and limited-privilege, and it is removed at handover with written confirmation.
Private LLM Infrastructure
Self-hosted LLM deployment on hardware you own. vLLM serving, private networking, validated output.
