Who's behind it
About DATA·QUERY
DATA·QUERY is a data and AI consultancy based in Barcelona. It was born from real experience working on large-scale data projects in the telecommunications sector, where order, cleaning and good architecture make the difference between useful data and ignored data.
That same approach — end-to-end, no shortcuts — is what we apply to every project, from a freelancer just starting to organise their data to a large company with complex systems: understand the business, organise the data, and build something on top that's actually used.
- End-to-end approachFrom the raw data source to the final decision, with no gaps along the way.
- Technical rigourClean SQL, documented architectures, and no "black boxes".
- ClosenessDirect dealings, no middlemen, adapted to the real size of your business.
- Product mindsetEvery project is delivered ready to use, not just "working".
