AI Tinkerers Barcelona - September Demo Night

🛠️ Real-World AI Implementation for Product Engineers
AI Tinkerers Barcelona is back on September 17, 2026, with an evening focused entirely on the practical aspects of building AI-powered products. This is a technical, live demo night with no slides, designed for senior software engineers, technical product managers, and product designers who are actively developing and shipping generative AI features, orchestrating LLMs, and building autonomous workflows.
We prioritize running code, architectural decisions, technical trade-offs, and lessons learned from real-world projects over theoretical or commercial presentations. Expect 4 to 5 fast-paced, 5-minute live demos from local builders showing what they built, how they built it, and what they learned along the way.

📅 Event Details

• Date: Thursday, September 17, 2026


• Time: 6:30 PM – 9:30 PM


• Location: OneCoWork Catedral, Av. de la Catedral, 6-8, Ciutat Vella, 08002 Barcelona


• Cost: Free to attend

Attendance is strictly limited and manually screened. To maintain a high-signal technical environment, we prioritize senior software engineers (5–10+ years of experience) working in product-driven SaaS companies, as well as professionals actively building and deploying AI solutions. Please make sure your profile includes links to your GitHub, LinkedIn, or relevant technical work.

🎙️ Submit Your Demo

Are you building something interesting? We want to see your experiments, custom LLM integrations, and solutions built for real-world environments. Demos are strictly limited to 5 minutes and must follow these core principles:

1. Show, Don’t Tell: Run your project live. Slide presentations are completely banned.


2. Expose the Internals: Share your tech stack, prompt engineering strategies, or agentic workflows.


3. Teach, Don’t Sell: Focus on technical discoveries and lessons learned, rather than pitching a product.

🧪 Science Fair & Networking

Alongside the main-stage presentations, we host an interactive Science Fair. This is a decentralized space during the networking sessions where participants can showcase projects from their laptops, run informal code walkthroughs, and get direct feedback from other professionals.
The evening will wrap up with food, drinks, and technical conversations with Barcelona’s builder and engineering community.
