What is a Sundai Hack? This is not your typical hackathon. Sundai intentionally drops the “-athon” — because this is something else:

No judges, no prizes, no competition

100% cooperation and co-creation

Group-wide brainstorming before building

Focus on learning, sharing, and a touch of frolic

Community-driven and grassroots — some bring code, others bring croissants

Sundai Hacks are run on Sundays by builders who care more about what we learn together than what we win.

Come build with us.

Picture billions of specialized AI agents—each with its own purpose—co-operating across a truly decentralized network. NANDA (Networked Agents And Decentralized AI) extends Anthropic’s Model Context Protocol (MCP) to make that vision real. On Sunday, 29 June 2025 we’re handing you the keys for eight intense hours of building, learning, and shipping.

📍 When & Where

• Date: Sunday 29 June 2025
• Time: 10:00 – 18:00 local time
• Location: Paris, Île-de-France (exact venue released to accepted hackers)

Space is capped at 20 builders, so far, and we vet every registration—lock your spot now or risk the wait-list.

⚡ What You’ll Do

• Form a lean team (1–5 people) or hack solo—your call
• Prototype an agent-based solution on the NANDA stack (or your own)
• Demo live code at 18:00—no slide decks, just running software
• Swap tips with MIT & Harvard researchers, AI Tinkerers core members, and fellow deep builders throughout the day
• Walk away with new friends, repo stars, and a fresh POV on decentralized intelligence

🗓️ Day-Of Flow

📊 Community Snapshot

• Attendance: This exclusive community of 4,082 subscribers comprises elite technical professionals, with 42% specializing in AI/ML research, 31% in full-stack software engineering, and 27% in technical leadership. Members possess deep expertise in PyTorch, LLMs, and agentic architectures. Notably, the group features prominent open-source maintainers from Hugging Face and graduates from top-tier institutions like École Polytechnique.
• Companies Represented: Featuring tech giants like Google, Meta, and Microsoft, alongside open-source and AI leaders such as Hugging Face, Mistral AI, LangWatch, and Black Forest Labs, and innovative startups like ElevenLabs, Docker, Datadog, Algolia, and Zoom, and more
• Demos: Across 130 submissions, 83 demos have been presented at AI Tinkerers - Paris. The most exciting themes have focused on agentic production workflows, knowledge-graph-driven reasoning (GraphRAG/context graphs), and system architectures for scalable, reliable deployments. Technically, structured outputs and tool/function calling, cost/latency reductions, eval/benchmarking, and multimodal/local execution have been repeatedly explored.
