contractes.cat: Catalan Public Contracts & Company Owners

Ask Claude about public procurement in Catalonia, and who is behind the companies that win it.

contractes.cat combines every public contract published on the Generalitat de Catalunya transparency portal (over 1.6 million records since 2014) with the owners and administrators of the winning companies from the Spanish companies register (BORME). That lets Claude answer questions no single official source answers:

• Which public contracts did a company win, from which public bodies, and how many bids competed?
• Who currently owns and administers a company, and which business group does it belong to?
• Which companies does a person control, and what contracts did those companies win while that person was in charge? Explicit "no contracts" answers included.
• Which companies receive the most from a town council, hospital, university or Generalitat department?

Example prompts: – "Did any of Joan Laporta's companies win public contracts while he ran them?" – "Who owns the top contractors of Barcelona City Council since 2023?" – "Find the largest cleaning contracts in Catalonia this year and the groups behind the winners."

Seven read-only tools: search_companies, get_company, search_people, get_person, search_contracts, search_public_bodies and get_public_body_top_companies. Every result links to the matching contractes.cat page, so answers can be checked and cited.

Built for journalists, researchers, procurement and compliance teams, and citizens. Works in English, Catalan and Spanish (contractació pública, contratación pública, licitaciones, adjudicaciones, BORME, Registro Mercantil, administradores).
