Who wrote this comparison.
OverFuture, a software company based in Zaragoza that also builds AI solutions, wrote this comparison. As an interested party, we leave ourselves out of the ranking and introduce ourselves under ‘About us’. No company paid to appear. We checked every source again on 10 November 2026, and each profile links to the pages we used.
How we scored each company.
Only part of Madrid’s technology sector actually develops AI. This list covers companies that build models, agents or AI systems for their clients. We left out consulting without development, profiles without a verifiable address and research centres, because they are not service companies.
| Criterion | Weight | How we check it |
|---|---|---|
| AI development for clients as a stated service | 25 | Its website: AI, generative AI, models or agents |
| Address in Madrid | 20 | Legal notice, privacy policy or contact page |
| Track record | 20 | Stated or registration year. 20 points for 20 years or more, 15 for 10 to 19, 10 for 5 to 9, 5 for fewer and 0 with no figure |
| Published AI case studies | 20 | AI projects with their own page; a tile on a shared page does not count. 20 points for two or more, 10 for one and 0 for none |
The services criterion differs from our software comparisons. Here AI development scores, not custom software in general, and a software project without AI adds nothing to the case studies. Public reviews (15 points) will arrive in January 2027. Until then the maximum is 85, and ties are listed alphabetically.
Declaration of interest. OverFuture offers the same service, so it is neither ranked nor listed in the table. Last review, 10 November 2026.

How to choose an AI company in Madrid.
- Start from one task you want to improve and the figure you will use to judge it.
- Ask for an AI case study with its own page and check what the company built itself.
- Ask where your data will be processed and who will have access to it.
- Ask how a person reviews the results before they reach your customers.
- Compare quotes for the same written brief, including maintenance.

Frequently asked questions.
Q2BSTUDIO, with 80 out of 85 points in the November 2026 review. Keepler follows with 75.
Because its website does not publish a starting year. If it does, we will count it in the next review.
Because we also offer artificial intelligence for businesses and would be judging ourselves. Our details are in the ‘About us’ box.
