    Why we exist

    "To create a forum for young professionals to discuss trilateral issues on a regular basis" — so the relationship survives leadership transitions, election cycles, and the gap between one summit and the next.

    • 01An organic cohort of early- to mid-career professionals who can carry on the conversation as they transition into policy influencers.
    • 02Short-form memos and working papers bringing practical insights to governments, industry, academia, and civil society organizations.
    • 03A resilient network that outlasts any single administration, election cycle, or exchange program.

    Our members

    86 members, nine countries, one working relationship.

    Members work across consulting, defense, energy, technology, and think tanks — plus a cohort still finishing PhD, JD, and MA degrees. Twenty-one are alumni of the original 2024 Youth Summit.
