Editorial summary · AI-drafted from public records

Private charitable foundation of Hansjörg Wyss. Focuses on land conservation, with $500M+ committed to protecting 30% of US land by 2030. Also funds progressive governance and policy organizations through direct grants and via intermediaries like the Arabella Advisors network. Foundation's political-adjacent giving has drawn scrutiny given Wyss's non-US-citizen status.
