Sub0 Symbiosis is a bold, immersive flagship conference for the Polkadot ecosystem — scheduled to take place on November 14–16, 2025, at the neo-brutalist Bubble Studios in Buenos Aires. Designed as a dynamic fusion of the Decoded and sub0 conferences, this three-day event brings together around 2,500 to 3,000 attendees, including developers, visionaries, VCs, students, and newcomers to the Web3 sphere. Attendees will experience a vibrant program featuring two engaging stages, curated talks, a 24-hour “Symbiosis Hackathon” with grants awarded to top teams, over 20 immersive themed rooms, private-chef catered meals, a rooftop beach, and a wide array of lively side events. The conference emphasizes resilient infrastructure, cross-ecosystem collaboration, and pioneering JAM protocol developments — while offering free entry, food, and drinks to fuel community experimentation and inclusion.
The organizer is WebZero, a trusted event team in the Polkadot world. They have already created more than 120 Web3 events in 12+ countries, hosted 5 hackathons, and engaged 11,000+ people. Their past event, “sub0 Reset” in Bangkok, was a big success.
Sub0 Symbiosis 2025 is more than just a conference — it’s an experience where builders, thinkers, and dreamers come together to shape the future of Web3.
