Doctrine strengthens its European presence by acquiring Maite.ai, Spain’s top legal AI platform
Doctrine, the primary legal AI company in Europe, has recently acquired Maite.ai, Spain’s leading legal AI platform. This acquisition, Doctrine’s fifth within three years, signals the company’s entry into the Spanish market and expands its customer base to 27,000 legal professionals across France, Germany, Italy, Spain, and Luxembourg.
Established in 2024, Maite.ai has quickly become a leader in Spain’s legal AI sector. The company experienced a twentyfold increase in ARR in 2025, serving over 2,000 customers, including solo practitioners, large law firms, corporate legal departments, and public administrations. Maite.ai offers a sophisticated legal AI assistant that supports the full legal workflow by utilizing legislation, case law, and user-uploaded private documents. With a remarkable accuracy rate of 99 percent on the Spanish judiciary access test, Maite.ai has proven its technological prowess.
The acquisition of Maite.ai solidifies Doctrine’s presence in Spain and aligns with the company’s objective to establish a European leader that caters to each country’s legal intricacies. Doctrine’s success is rooted in its unique market position, combining deep knowledge of local legal data (laws, regulations, commentary, and case law) with the private information of legal professionals (contracts, pleadings) to assist them at every phase of their work. Doctrine provides legal professionals with a legal AI solution grounded in European technological sovereignty that adheres to GDPR regulations and maintains the highest information security standards, including ISO 27001.
Doctrine’s recent acquisition of Maite.ai is part of an overall strategy of profitable organic growth accelerated by successful mergers and acquisitions. With previous acquisitions like Legaltile and Jobexit in 2023, and Dejure and Predictice in 2025, Doctrine has expanded its reach across Europe significantly. Presently, Doctrine serves 80 out of France’s top 100 law firms and caters to clients in both the private and public sectors. The company’s influence extends into Germany, Italy, Spain, and Luxembourg, establishing it as a prominent legal AI provider in the region.
Guillaume Carrère, CEO of Doctrine, underlines the importance of integrating Maite.ai to strengthen their position as the European leader in legal AI. As the global AI market continues to evolve rapidly, Doctrine remains focused on building a trustworthy European leader grounded in technological sovereignty. The acquisition of Maite.ai has further propelled Doctrine’s growth trajectory, following their most substantial year of growth in 2025.
Alejandro Castellano, CEO of Maite.ai, emphasizes the significance of joining forces with Doctrine to enhance their leadership in Spain sustainably. By combining their technology with Doctrine’s expertise, Maite.ai can offer clients a robust solution supported by a decade of industry knowledge. Maite.ai will maintain its brand, headquarters, and team, preserving its identity in this new chapter of growth and expansion.
Moving forward, Maite.ai’s team will continue to lead the Spanish market, with plans for significant hiring to support ongoing growth. The platform will benefit from synergies with Doctrine’s extensive experience in artificial intelligence, positioning the company to serve the needs of over one million lawyers and legal professionals across Europe. This expansion will unlock significant growth opportunities within the European legal landscape.
