Source Check Verdicts
Last checked: 4/14/2026
The source is a staff directory from California YIMBY's website showing current team members. Zack Rosen is not listed among the staff. While the source could theoretically be incomplete or outdated regarding historical founders, the absence of Zack Rosen from a comprehensive staff listing does not directly contradict the claim—he may have been a co-founder who is no longer actively listed as staff, or the source may simply not include historical founder information. The 2017 start date cannot be verified or contradicted from this source. This is unverifiable rather than contradicted because the source does not explicitly state who the founders are or when the organization was founded.
