Preamble Windfall Foundation

The Preamble Windfall Foundation Inc. is a 501(c)(3) nonprofit organization headquartered in Pittsburgh, Pennsylvania, with its IRS ruling year in 2022. The foundation shares an address with Preamble (the AI cybersecurity company) at 1001 Liberty Ave Suite 500, Pittsburgh, PA 15222, and is associated with Preamble co-founder Jonathan Rodriguez Cefalu, a Stanford Computer Science graduate and Forbes 30 Under 30 honoree who sold his AR startup Vergence Labs to Snapchat in 2014 before co-founding Preamble in 2021. The foundation's most visible initiative is the Planetary Animal Welfare Survey (PAWS), hosted at paws-survey.org, which sought to compile the most comprehensive literature review of neuron count estimates across animal species. The goal was to give philanthropists a rigorous empirical basis for directing animal welfare donations to the species or genera whose aggregate wellbeing can benefit the most from charitable aid, effectively functioning as a decision-support tool for effective animal welfare giving. The foundation is classified under the NTEE code for Education N.E.C. and files Form 990-N with the IRS, reflecting annual revenues under $50,000. It is a small, likely family-operated philanthropic vehicle consistent with Cefalu's stated charitable priorities, which include AGI alignment research, nuclear disarmament, wild animal suffering, and factory farming elimination. The foundation accepts donations at preambleforgood.org.
