## Summary

Anthropic has opened its first office in Spain, in Madrid, led by Cristina Pitarch, bringing the number of its European locations to seven. According to Anthropic's Economic Index, usage of Claude in Spain is 2.7 times higher than its population size would suggest. The company says its customers already include Santander, BBVA, CaixaBank, Telefónica, Indra, Konecta, Amadeus and Ferrovial, with uses cited in software development and cybersecurity at Telefónica, civil engineering at Ferrovial and travel information access at Amadeus. Anthropic has also entered into a partnership with ISDI Business School to support its developer community in Madrid. The opening is part of a European expansion in which EMEA headcount has tripled in one year and the region's annualised revenue has grown more than ninefold.
