The garage is wherever you build.
Silicon Valley Buildathon takes its cue from the workbench. Start with a rough idea, build the part you’re most curious about, and get it working well enough that someone else can try it.
Maybe it’s a browser tool that saves ten clicks, a game with a mechanic you’ve never seen, or a device that makes an ordinary task easier. An app, an AI experiment, a hardware prototype, and an interactive story all have a place here. Use whatever tools make sense for your idea.
Show us the moment the project comes to life. Let us see someone use it, walk us through a choice you made, and tell us what changed after your first test.
Build and submit November 8–December 15, 2026. Judging is planned for December 16–20, with results on December 21.
Submit an original prototype in any category. Include a description of the problem or creative goal, a demo or visual walkthrough of the core feature, and a short explanation of what you built and tested. Share accessible project links where available, credit reused tools and assets, and explain what each team member contributed.
