Europe's sovereignty is no longer an abstract political ambition - it is being built now, line of code by line of code, satellite by satellite, city by city. This panel brings together the pioneers who are actually doing it: securing critical infrastructure, certifying sovereign cloud environments, launching national space constellations, and turning mid-sized European cities into deep-tech hubs. From the French-Polish axis to the broader question of what it truly means to keep strategic technology inside European hands, this conversation will go beyond the buzzwords - and get honest about what it takes to scale sovereignty in the real world.
