Institute for AI Policy and Strategy — Headquarters: San Francisco, CA

Note: The source text from IAPS's contact page explicitly lists a mailing address in San Francisco, California. While the source notes this is their fiscal sponsor's address (Rethink Priorities), it directly confirms San Francisco, CA as a headquarters/primary office location. The additional context about remote-first operations and DC-area presence does not contradict the claim of San Francisco as the headquarters location—it simply provides supplementary information about organizational structure.
