The Survival and Flourishing Fund (SFF) is a grant-allocation vehicle, backed chiefly by the Skype cofounder [Jaan Tallinn](/people/jaan-tallinn/), that directs money to organizations concerned with the long-term survival and flourishing of sentient life. It uses a software-assisted allocation method called the S-process to convert the judgments of a rotating panel of evaluators into grant recommendations, and it has become one of the central funding channels of the [Effective Altruism](/concepts/effective-altruism/) and longtermist ecosystem, channeling money to AI-safety, biosecurity, and existential-risk groups. By its own accounting it has organized roughly 150 million dollars in gifts across its rounds.[^1][^2]

### Origins and Funders

SFF grew out of Tallinn's earlier "Survival and Flourishing" donations, the loose label under which he had been giving to existential-risk and rationalist organizations, and it was formalized in 2019 with an initial grant of about 2 million dollars from the Organizational Grants Program of the [Berkeley Existential Risk Initiative](/organizations/berkeley-existential-risk-initiative/) (BERI), itself funded by Tallinn's philanthropy. The structure let Tallinn delegate the evaluation of applicants to a committee rather than make every funding decision himself, while retaining final authority over whether to act on the recommendations.[^1][^3]

Tallinn remains the dominant funder, but other donors have joined particular rounds, including the Ripple cofounder and cryptocurrency philanthropist Jed McCaleb and the [Future of Life Institute](/organizations/future-of-life-institute/). The fund's operations are run by Survival and Flourishing Corp (SFC), a separate entity that administers the rounds and the grant-making software; figures associated with its management have included the AI-safety researcher Andrew Critch and the software engineer Eric Rogstad. Annual distributions have ranged from the roughly 2 million dollars of the 2019 round to more than 40 million dollars in 2024.[^1][^4]

### The S-Process

The S-process (the "S" stands for "simulation") is the recurring procedure SFF runs once or twice a year to turn human judgment into dollar allocations. Each round recruits a panel of roughly four to twelve "recommenders" chosen by the funders, who review the applications and each express a marginal-value or utility function describing how much they think additional money to each organization is worth. A grant-making application then simulates the funding process, combining the recommenders' functions so that the system favors projects with enthusiastic individual champions rather than only broad consensus picks. SFF has credited the method's development to Andrew Critch, Tallinn, Oliver Habryka, Kevin Arlin, and Jason Moggridge.[^1][^5]

The mechanism is designed so that recommenders are given equal weight, in effect producing a synthetic average evaluator, while funders retain final say over whether to implement the output. In recent years SFF has run multiple parallel tracks within a single round; the 2025 round used twelve recommenders split across a six-person Main Track and two specialized three-person tracks named the Fairness Track and the Freedom Track, and it also offered matching pledges under which Tallinn committed to match outside donations at set rates. SFF separately operates a faster "Speculation Grants" program for time-sensitive funding between the main rounds.[^5][^6]

### Organizations Funded

SFF's grants have flowed to the core institutions of the AI-risk and existential-risk field. Recipients across its rounds have included the [Machine Intelligence Research Institute](/organizations/machine-intelligence-research-institute/), the [Centre for the Study of Existential Risk](/organizations/centre-for-the-study-of-existential-risk/), the Future of Life Institute, and a wide range of newer AI-safety, governance, and biosecurity groups. The 2025 round alone recommended about 34.3 million dollars, with named grants including 2.035 million dollars to the AI Futures Project, 1.635 million dollars to the AI Policy Institute, 1.607 million dollars to the Machine Intelligence Research Institute, 1.5 million dollars to the biosecurity project SecureDNA, 1.311 million dollars to Lightcone Infrastructure, and 1.133 million dollars to Palisade Research.[^6][^7]

Other recurring beneficiaries have spanned technical alignment research, AI-policy advocacy, pandemic preparedness, and the rationalist community infrastructure that hosts much of this work, with individual grants typically ranging from around 10,000 dollars to well over a million dollars. Critics of the broader field have noted that a small number of donors, with Tallinn prominent among them, supply much of the money that funds the organizations scrutinizing advanced AI, a concentration that the S-process distributes but does not eliminate.[^2][^6]
