Founded in 2025 and headquartered in San Francisco, Nirva (Nirva Labs) builds a consumer AI wearable: a roughly 10-gram titanium pendant worn as a necklace or bracelet, with dual microphones, a UV light sensor and an IMU, IP67-rated and lasting about two days per charge. The device recognizes and listens only to the wearer's own voice, turning a day of conversation into an automatic life journal, while the companion app's AI analyzes tone, word choice and vocal energy to track mood and map social relationships, labeling the people around the wearer as energizing, neutral or draining, then delivering daily guidance in text or voice. Press coverage has described it as an Oura for emotions. It targets individual consumers focused on self-awareness and wellbeing. The hardware module is priced around $200, accessories $30-50, and the app subscription about $12-14 per month, with preorders opening in February 2026 and shipping in the first half of the year.
