“AI infrastructure is the new sovereign asset class.”
Lina Brennan is Cayman Journal's technology correspondent, covering AI infrastructure, cloud markets, and the deal flow shaping the next computing era. Before journalism she spent eight years as a venture partner backing infrastructure software, an apprenticeship that lets her read a co-location lease or a GPU procurement contract as quickly as a balance sheet. She covers the companies, contracts, and energy questions that decide whether the AI build-out lives up to its valuations, and writes the weekly Stack Trace column on the politics of compute. Lina trained as an electrical engineer at MIT, holds a master’s in computer science from Stanford, and is a contributing fellow at the Oxford Internet Institute.
