Firms To Watch: TMT

With its September 2023 absorption of pioneering computer law boutique Altmark y Brenna, Zang, Bergel & Viñes Abogados has very much positioned itself as a player in the TMT sector, certainly as regards the digital transition segment; led by Juan Pablo Altmark, the firm's new computing law practice handles matters including technological implementation, data protection, AI, blockchain, cybercrime, and the contracting of technology and computing services.
Cristian Elbert and Angeles Bernachea are the main contacts at ECIJA Argentina which advises both technology and other companies with digitalisation and technology-related matters, and counts fintech and online sales as key areas of activity; the practice can also draw on the cutting-edge expertise of the firm’s practice group in Spain, which is very much recognised as a market leader in the tech sector.
