Nirva secures $33 million for voice-filtering AI pendant

Nirva raises $33 million for wearable personal insights device
Nirva has raised $33 million to develop an AI wearable designed to listen only to its wearer. The total includes a newly announced $25 million pre-Series A round and $8 million raised earlier this year from investors including Lightspeed Venture Capital and South Park Commons.
The company, founded in 2025, plans to begin taking orders in November for its first product: a $249 pendant that can also be worn as a bracelet. Nirva aims to ship the device to early users by the end of the year.
The hardware weighs about eight grams and is intended for all-day wear. Nirva says its battery can last up to three days on one charge. Buyers will be able to choose silver, brushed silver, black or gold finishes.
Voice identification is central to Nirva’s privacy claim
Nirva was founded by former Meta Reality Labs employees Wei Lyu and Jason Chen, alongside Hanying Hu, who founded a fashion and jewelry brand. The startup says it wants to combine a jewelry-like form factor with a system that passively listens to the wearer’s own speech rather than operating as a conventional voice recorder or meeting-notes device.
The approach addresses a central concern around ambient AI hardware: people nearby may not want their conversations recorded. During onboarding, Nirva asks users to record snippets of their voice. It then uses that information to build a model intended to distinguish the wearer from other people around the device and filter out conversations and data from those other people.
Nirva says it does not retain audio data or transcripts by default after conversations are processed. Before discarding the audio, the system can analyse tone, pitch, volume and speaking speed. The company says those signals help it derive emotion-related understandings that are presented in its companion app.
From captured speech to personal prompts
Nirva describes itself as a personal insights company rather than a productivity startup. Its app can nevertheless surface reminders, action items and suggested ways to act on them. The app also produces inferred observations about patterns in a user’s speech, the people who tend to be around them, places they have been and other daily notes.
Lyu said the product is intended to support self-understanding, self-compassion and self-awareness. Nirva also says it can highlight emotional patterns and communication style, including prompts that encourage users to follow through on an interaction or acknowledge someone in their lives.
The company enters a growing market for AI wearables. Taya, founded by former Apple employees, is developing intelligent jewelry, while Friend and Bee are pursuing companion-gadget concepts. Nirva has said it intends to release additional devices over time.
Business implication
For businesses assessing ambient AI products, Nirva’s launch highlights the importance of testing voice-recognition boundaries, bystander-data filtering and default retention practices before relying on generated personal insights.
