NoteThe source is the official Redwood Research website homepage and contains extensive information about their research, focus areas, team links, and blog posts. However, it does not include any mention of their headquarters location, address, or geographic base. While the claim specifies 'San Francisco, CA' as the headquarters, the source text provided does not address this claim at all. To verify this claim would require additional source material such as an 'About Us' page, contact information, or other documentation that explicitly states the headquarters location.
