Today, San José Mayor Matt Mahan used his campaign X account to lean hard into his Silicon Valley origin story, saying that when he co-founded Brigade and worked at Causes, he helped build tools that later became change.org and GoFundMe and pledging that as governor, he would keep empowering grassroots organizers. The post landed as Mahan works to stand out in a crowded Democratic primary by showcasing his civic-tech résumé. It also drew fast scrutiny because the two platforms he name-checked launched years before Brigade existed.
What He Said And How It Checks Out
In the post on X, Mayor Matt Mahan cast his rise to City Hall as an outgrowth of his civic-tech work, treating Brigade and Causes as the launchpad for his political career. His campaign biography lists him as a co-founder of Brigade and a former executive at Causes, a storyline that has become central to how he introduces himself to voters statewide.

When I co-founded Brigade and worked at Causes, we built tools to help people organize grassroots movements. Tools that later became https://t.co/vbtmMceNF7 and gofundme.

Timeline Problem Over Change.org And GoFundMe
The eye-catching part of the post was Mahan's claim that his team's tools later became change.org and GoFundMe. Public timelines do not back that up. Change.org launched in 2007, and GoFundMe traces its start to 2010. Brigade came along later, creating a chronological gap that makes his phrasing, at best, hazy.
Charitably read, Mahan may have been referring to the continuity of civic-tech ideas rather than to a direct product handoff. Still, when you tell voters your work "became" two household-name platforms that were already up and running, you are inviting people to pull out the calendar.
Where Brigade's Work Landed
Brigade's actual legacy is more modest and more typical of a Silicon Valley startup exit. In 2019, its assets and engineering team were split and sold. The engineering staff was acqui-hired by Pinterest, while Countable picked up Brigade's technology and data. Some of the voter-matching code was later open-sourced. That means Brigade's ideas and code have echoed through later projects, but it does not make Brigade the literal origin of platforms that predate it. (TechCrunch)
Why The Moment Matters For Voters
Mahan is trying to turn his Silicon Valley résumé into governing credibility as he introduces himself to voters far beyond the South Bay. Outlets like the Los Angeles Times have noted that he is centering a blend of civic-tech chops and local results in his pitch for governor.
That is why a single X post suddenly matters. The tweet folds a familiar tech-founder origin story into a high-stakes campaign moment and drags niche civic-tech history into the middle of the governor's race. As the primary heats up, supporters and skeptics alike are likely to keep asking whether Mahan is talking about influence or claiming lineage and whether that distinction matters to voters who care more about what he will do in Sacramento than what he built in a SoMa office years ago.
