Survival and Flourishing Fund (SFF)

Funder

Also known as: SFF

SFF distributed $141M since 2019 (primarily from Jaan Tallinn's ~$900M fortune), with the 2025 round totaling $34.33M (86% to AI safety). Uses unique S-process mechanism where 6-12 recommenders express utility functions and an algorithm allocates grants favoring projects with enthusiastic champions, though the mechanism can produce volatile grant distributions year-to-year.
