Garry Tan Exposes Doxxer Brandee Marckmann Running for San Francisco School Board

Garry Tan revealed on February 17, 2026 that Brandee Marckmann, the activist who doxxed his home address in 2022 and forced his family to move, is running for San Francisco School Board. The disclosure places Marckmann's candidacy squarely in the spotlight for San Francisco County voters ahead of the next school board cycle.

The doxxing incident in 2022 is central to Tan's disclosure: Marckmann published Tan's home address in a context that the Tan family has said led them to relocate. That 2022 action is the specific fact Garry Tan cited when announcing Marckmann's run on February 17, 2026, linking a past safety incident to a present campaign for seats that oversee San Francisco public education.

Brandee Marckmann is identified in Tan's revelation as an activist; Garry Tan framed her 2022 conduct as directly relevant to her bid for the San Francisco School Board. Voters and district stakeholders in San Francisco County now have a concrete connection between Marckmann's past behavior and her intent to seek authority over school policy, budgets, and student safety at the district level.

The timing of Tan's disclosure on February 17, 2026 intervenes as San Francisco County prepares for upcoming local elections and school board contests. The revelation raises questions about candidate vetting and the kinds of background issues that San Francisco School Board candidates may bring into public debate, particularly when those issues involve doxxing and threats to the safety of families.

Community leaders, parents, and San Francisco School Board watchers will have to weigh the details Tan provided about the 2022 doxxing against Marckmann's decision to run for school governance. With Garry Tan publicly naming Brandee Marckmann on February 17, 2026, the local conversation over candidate fitness and school safety has a specific, documented episode for voters in San Francisco County to consider as they evaluate candidates for the San Francisco School Board.
