Vitalist Bay is a longevity-focused popup city that ran in spring 2025 at the Lighthaven campus in Berkeley, California, billed as the world's largest longevity zone. The event offered residents and visitors coliving, co-working, advanced health diagnostics such as DEXA scans and VO2max tests, and weekly conferences spanning aging biology, biostasis, longevity investing, and health practices.

It was designed as a microcosm of what a longevity-oriented state would look like, leveraging the Bay Area's concentration of AI labs, biotech firms, and venture capital.
