With a Master's degree in Earth Sciences from the University of Rennes 1 (France) in 1997, François Soulard first worked as a project manager for the Nord-Pas de Calais Regional Council on sustainable development and environmental education. As an adventure enthusiast and young internationalist activist, he created the Traversées association in 2003 to embark on a three-year itinerant journey around the world, with the aim of exploring ways of organizing societies and approaches to development. In 2008, he settled in Argentina and participated in various social movements and citizens' assemblies in Latin America, Africa, and Asia, in connection with the movement Alliance for a Responsible, Plural and United World.

In 2012, coinciding with the Rio+20 Earth Summit, he founded the digital communication platform Dunia with two Latin American engineers. The platform is technically based on open-source software and helps networks and institutions use information for organizational, strategic intelligence, and communication purposes. Geopolitical issues and the strategic use of information have gradually become central to the platform's agenda. Control of cyberspace took on a new meaning, while informational power correlations have changed the face of conflicts and modes of confrontation since the 1990s. François Soulard participated in initiatives such as the Forum for a New World Governance, the Dictionary of World Power published in French and Spanish, and initiatives advocating for a citizen and sovereign Internet (World Forum of Free Media, Forum for a Citizen Internet, For a Digital New Deal).

As of 2018, Dunia conducted several studies on information warfare, in particular on the logic of power at play in the Amazon, mining conflicts, the Russian-Ukrainian war, and China's combative emergence. He is developing collaborations with the School of Economic Warfare, the World Forum of Social Economy, and the Institute of Economics. In 2023, François Soulard published "Una nueva era de confrontación informacional en América Latina" in Spanish (Ciccus, Buenos Aires, 2023). He has also translated several works by the geostrategist Gérard Chaliand (Atlas estratégico, Por qué Occidente pierde la guerra, Terrorismo y política). In addition to the digital services provided through Dunia, his work now focuses on strategic cultures, changes linked to informatization, and information and economic combativeness.
