Experience

Natalia Martos has spent most of her professional life at Grupo PRISA, as an in-house lawyer, having started her career in its digital division and later becoming a lawyer for the Secretary General. She was subsequently appointed General Counsel and Chief Privacy Officer of the Spanish social network Tuenti, until its sale to Telefónica. After this period, she returned to Grupo PRISA to lead the group's digital transformation for more than four years as Corporate Legal Director of Digital Business and Global Chief Privacy Officer. During her last two years at PRISA, she was director of legal advisory services for Prisa Noticias and Prisa Brand Solutions.

After more than 12 years as a corporate lawyer, she began practicing law in law firms, debuting as a partner at Andersen Tax & Legal, where she created a new practice area, “Privacy, IT & Digital Business.” Once established, she created and developed this same practice area at the Pérez-Llorca firm, advising all types of industries on their digitization processes, compliance with the new Data Protection Regulation, as well as on all activities related to business law, intellectual and industrial property, digital business, technological assets and, in general, in all activities typical of legal departments of companies of all sizes and industries.

In early 2018, he founded Legal Army, one of the first ALSPs in Spain, where he developed the practice of technology law, intellectual property, innovation, and privacy focused on exponential technologies applied to different sectors of the economy and using legaltech tools to multiply the efficiency of his team. In 2021, his firm, Legal Army, was included for the first time in the renowned international directory Chambers & Partners in the ALSP (Alternative Legal Services Provider) category and achieved the coveted Band 1 ranking in 2023.
