About New York · October 2026

Two weeks of NYC are mostly community-level, with one big fintech date and a demo day still ahead. Swell 2026 by Ripple runs Oct 27 at The Shed, where Brad Garlinghouse and traditional finance names share a stage with the onchain crowd, so it matters if you build in crypto or payments. Techstars NYC Demo Day on Dec 10 puts a full cohort in front of investors. In the meantime, The AI Collective's founder roundtable (Oct 14) and Propeller's Infra Demo Night (Oct 15) are the better small rooms.
