Submit a live system and its URL (mandatory) and present it (opt-in), alongside the Builders cohort. You show the whole stack: a grounded, agentic, evaluated, memory-holding system, and how you know it works.

Running it jointly with the Builders is deliberate: an engineer presenting the agent underneath next to a founder presenting the product on top is where the two cohorts see the full craft, and where a lot of people find their next rung.
