Regulated industries silo designers. We report a cross-bank UX network in Japan that convenes practitioners under compliance-safe norms (e.g., Chatham House Rule, no competitive intel). In discovery sessions, designers highlighted: constrained career paths, tool-centric drift, uneven AI ethics, and difficulty articulating human value to business. We piloted three tracks: (1) Career & Craft Clinics; (2) Practice Exchange with anonymized cases; (3) a Philosophy-in-Practice colloquium drawing on value sensitive design, mediation theory, and communicative AI. Early signals show clearer ethical language, stronger cross-institution collaboration, and greater confidence in framing design’s business value. The poster shares governance templates, session formats, and facilitation tips so others can replicate the model. Our claim: structured philosophical inquiry is a practical lever for better decisions in high-stakes, data-heavy services — not an academic luxury.
