Power the builders defining our digital future.

MozFest is Mozilla’s flagship festival and the most trusted convening for an open, human-centered internet. For 15 years, it has united technologists, policymakers, creators, and activists to unlearn harmful systems and prototype better futures.

By partnering with MozFest, you connect directly with builders, decision-makers, and culture-makers who shape the digital landscape — and gain meaningful opportunities to showcase your brand, spark adoption, and drive influence where it matters most.
