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

NoteThe source directly confirms that the Institute for AI Policy and Strategy has a San Francisco, California address (530 Divisadero St., San Francisco, California 94117) listed as their mailing address on their official contact page. While the source does not explicitly state 'headquarters,' the mailing address provided is in San Francisco, CA, which aligns with the claim. The additional context noting a 'primary office in San Francisco' and 'DC-area presence for policy work' is consistent with the source showing San Francisco as the official mailing address.
