The vehicle, closed in the first quarter and unveiled today, will pour most of its capital into Solana-focused startups. CEO Victor Fischer, a computer science engineer and former McKinsey consultant who bought his first bitcoin in 2015 because a coworking beneath his Prague flat accepted nothing else, began running Solana software from an apartment back when rivals insisted the blockchain needed plush data centers. That tinkering became RockawayX’s calling card: the firm now oversees about $2 billion, operates its own data centers and employs 45 people, two-thirds of them engineers, across Prague, Dubai and London offices.
