The Builder Base: Buildathon Your idea. Your stack. Your build. Welcome to The Builder Base: Buildathon — a one-day gathering in San Francisco for engineers, AI builders, founders, designers, and technology professionals who want to spend a full day turning ideas into working products. Builder Base is built around one simple idea: give builders the space, tools, people, and time to build. Whether you're experimenting with an AI agent, launching a developer tool, creating an enterprise workflow, building a data product, automating a painful process, or working on something completely unconventional, this is your base for the day. Come with an idea, a problem, a technology you want to explore — or nothing more than the desire to build. Find teammates, get feedback from experienced builders, learn from industry experts, and ship something you're proud of. Event Details When: 9:30 AM – 7:00 PM, 30 October 2026 Where: San Francisco, CA Format: One-day, in-person buildathon Who: Engineers, AI Builders, Founders, Product Managers, Designers, Data Scientists, and Technology Professionals Theme: Open-ended — Build what matters What to Expect - A full day dedicated to building - Turn an idea into a functional prototype - Collaborate with engineers, founders, designers, and AI practitioners - Meet potential teammates and future collaborators - Mentorship and guidance from experienced industry professionals - Access to modern AI tools, APIs, platforms, and developer resources - Partner credits, challenges, and special prizes - Live product demos and project showcases - Networking with San Francisco's technology and startup community - Food, refreshments, swag, and prizes What Can You Build? Anything worth building. Build an AI application, autonomous agent, developer tool, enterprise workflow, data platform, automation system, productivity tool, consumer product, infrastructure project, or an idea nobody has tried before. There are no prescribed problem statements and no requirement to build around a particular technology. Find a problem. Build the solution. Ship it. You can arrive with a fully formed idea or figure it out once you get there. The goal is to spend the day building, experimenting, learning, and turning an idea into something real. Who Should Join? The Builder Base is for people who make things. Whether you're an experienced software engineer, an AI developer exploring agentic systems, a founder testing a new idea, a product manager turning a concept into a prototype, a designer bringing an experience to life, or a student and early-career developer looking for your next challenge — you're welcome. You don't need to be an expert. You just need to be ready to build. Come with an idea. Leave with a build.
