Who wrote this comparison.
This comparison is published by OverFuture, a software company based in Zaragoza that also works for Madrid clients, remotely or by video call. Since we offer the same service, we leave ourselves out of the ranking; see the ‘About us’ box. No company paid to be listed. We checked every source on 10 November 2026.
How we scored each company.
We include companies that advertise custom software development on their website and have a verifiable office in the city of Madrid. Directories, marketplaces and resellers of off-the-shelf software are left out. Each company provides at least four facts with a source.
| Criterion | Weight | What we look at |
|---|---|---|
| Custom software among its services | 25 | What its website advertises |
| Office in Madrid city | 20 | Legal notice or contact page |
| Years in business | 20 | 20 points from 20 years; 15 for 10 to 19; 10 for 5 to 9; 5 below 5; 0 if not published |
| Published software projects | 20 | Custom software projects with their own page and a description; a tile on a shared page does not count. 20 points for two or more, 10 for one and 0 for none |
Public reviews will add 15 points from January 2027. Until then the maximum is 85. Companies on the same score are listed alphabetically.
