Fort is a Y Combinator (W26) hardware startup building a screenless wearable that automatically tracks strength training for people who care about longevity. Founded by three former Tesla engineers, the device uses heart rate and motion sensing to detect gym sessions, workout classes, sleep, and recovery without requiring the wearer to manually log reps, sets, or exercises, then delivers actionable feedback on how lifestyle factors affect strength progress. Fort is styled as jewelry rather than performance gear, ships in three finishes with 7+ day battery life, and pairs with Fort Foundations, an expert-led training program built around core movement patterns. The product is currently available for pre-order and has no public developer API or programmatic surface at this time; this profile captures the company's public web and commercial presence.
