Jaan Tallinn is an Estonian programmer and investor, a founding engineer of Kazaa and Skype, who became a private funder and institution-builder in the AI-safety and existential-risk field. He co-founded the Future of Life Institute and the Centre for the Study of Existential Risk, is a principal backer of the Survival and Flourishing Fund, and signed the Statement on AI Risk.
Background
Tallinn was a founding engineer of the file-sharing application Kazaa and of Skype. He subsequently became active as an investor and as a funder of catastrophic- and existential-risk research.
Roles and institution-building
Tallinn co-founded the Future of Life Institute (FLI) in 2014, the organization behind the 2023 "pause" open letter and the Statement on AI Risk; see Future of Life Institute (FLI). In 2012 he co-founded the Centre for the Study of Existential Risk (CSER) at the University of Cambridge, an early academic home for catastrophic- and existential-risk research. He has also been associated with the founding or early support of the broader Effective Altruism–adjacent existential-risk ecosystem.
Funding
Tallinn is a principal backer of the Survival and Flourishing Fund (SFF), which uses an algorithmic "S-Process" to allocate grants and has organized on the order of $150 million across 300+ projects, including capability-evaluation and forecasting organizations such as METR and Epoch AI and safety bodies such as the Center for AI Safety (Source: survivalandflourishing.fund). Through these vehicles Tallinn has been an upstream financial source for many technical-safety and AI-governance organizations. His philanthropy was recognized on the 2026 TIME100 Philanthropy list (Source: time.com).
Positions and statements
Tallinn is a long-standing public advocate of the view that advanced AI poses catastrophic and existential risks warranting precaution, and a signatory of the Statement on AI Risk. He aligns with the superintelligence-concerned camp (Yoshua Bengio, Stuart Russell, Max Tegmark, Machine Intelligence Research Institute (MIRI)). Critics of that camp note that the same network of funders, including Tallinn's SFF, shapes which safety questions get resourced, a structural point about the field rather than a claim about any individual grant.
