Seattle’s monthly meetup combines hands-on Science Fair stations with curated Mainstage demos, AI news updates, and conversations— and starting January, doors open at 5pm and the Science Fair starts at 5:30pm (check agenda for details).

Connect with the most ambitious engineers and researchers to trade notes, debug systems side-by-side, and get fresh eyes on your project. Selective by design, space is strictly limited to 150 vetted builders.

Demos, Not Decks

This event is built around the demo. We encourage messy experiments, creative hacks, and technical discoveries in action. Your presentation must answer: “How did you even build this??” Working code or nothing.

All approved demos will participate in the Science Fair, setting up hands-on stations for deep-dive Q&A and peer review. Two or three demos will be selected for the Mainstage.

Mainstage Demos: Capped at 5 minutes. 

Science Fair Stations: Capped at approximately 45 minutes per group.

This is for hands-on technical Q&A at your station. Bring your laptop and be ready to pop the hood on your stack.

Sponsor Spotlight

We thank Copilotkit for enabling this builder-focused event.

CopilotKit - CopilotKit is the open-source framework developers use to seamlessly integrate deeply integrated AI copilots into their React applications. It provides the essential infrastructure, including robust React components and a Multi-Copilot Protocol (MCP) server and client, to build sophisticated AI assistance. This powerful tooling enables developers to quickly add customizable, context-aware AI features, such as autocompleting textareas or full-fledged AI coding agents, significantly enhancing user experiences. We’re excited about their latest 1.5 release which enables durable, long-running agents that feel native to your product.

Partner with the Builders

We maintain a selective sponsorship model: only brands that ship get in. If your company builds infrastructure, models, or tooling that accelerates the work of engineers and researchers, we should talk.
