  • Ministère de l'intérieur
    Company Research Officer - Strategy and Foresight Mission
    PUBLIC SAFETY
    August 2017 - October 2018 (1 year and 2 months)
    Paris, France
    Within the Strategy and Foresight Unit of the Directorate-General for Civil Security and Crisis Management, I was responsible for analyzing for the management the main trend evolutions in French society (demographics, spatial organization, employment changes, technological innovation dynamics, lifestyles...) in order to adapt civil security policies by 2030.

    Under the supervision of Colonel Morin, I produced a multi-thematic foresight study of about a hundred pages, with diagnosis and recommendations for several areas of change, communicated internally (as well as to certain partners and industrialists).

    This research, documentation, and monitoring work (academic articles, specialized press, regulatory texts, public reports, think tank conferences...) as well as collaborations with IFRASEC and IHEMI allowed me to durably refine my perspective on the following topics:

    • Foresight research and sociology
    • Risk and crisis management
    • Situational prevention and emergency services
    • Citizenship, volunteering, and resilience
    • Territorial intelligence
    • Dynamics of an industrial ecosystem
    • Integration of technological innovations

Mathieu's proposals perfectly met our initial objectives. In addition to his email sales techniques, Mathieu implemented a very effective client acquisition system on LinkedIn. I didn't realize this network offered so many opportunities in our industry. With his rigorous organization and professionalism, Mathieu truly dug into our needs, which explains why his initial proposals are often spot on. His work was very useful to us, both in understanding marketing challenges and in execution (a clear and effective writing style). I recommend him.
