​This meetup is for anyone building with OpenClaw (& Claude Code) or experimenting with other AI tools to create agents that can act and make decisions on their own. If you haven’t tried these yet, come hang out, ask questions, and see what others are building. We’ll trade notes, troubleshoot setups, and explore what it takes to run these systems openly on the web instead of inside closed platforms. Bring your laptop, grab some power, and jump into a night that feels part LAN party, part live build session, where people test ideas and show what their agents can actually do. 👉 [RSVP on LUMA](https://luma.com/53dx7no1) We’ll also have some fun by running a live test to see if a few of our agents can send Bitcoin back and forth and talk about why that’s a meaningful step for autonomous AI. It’s a chance to connect the dots between open AI tools, Bitcoin, and the wider goal of creating technology that no one can turn off. 👉 [RSVP on LUMA](https://luma.com/53dx7no1)

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

APIs power virtually every web and mobile application, accounting for over 80% of all Internet traffic. And APIs are under attack. Gartner states APIs have become the “most frequent attack vector," resulting in hundreds of highly successful, high profile breaches. This API security presentation covers 1) why attackers love APIs, 2) real-world breaches (and how they map to the OWASP API Security Top 10), and 3) best practices to keep APIs secure.

AI is changing how art is made. But when does it stop being your work and start being the machine’s?

We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
