What you likely need
You'd get the most out of Festival events that sharpen your dual founder-GP narrative in front of institutional capital and top-tier AI builders. High-signal dinners with SoftBank and ICONIQ-connected GPs, YC batch mixers for Valon deal flow, and A2A economy thought leadership roundtables are your highest-leverage plays. Events that connect your Korean tech bridge identity to US expansion deals and give you peer cover on the COO/Principal delegation question will also move the needle fast.
