Nirva Announces $25M Round for Voice-Isolating Pendant
Nirva has announced a $25 million pre-Series A funding round, which brings the company's total funding to $33 million, including $8 million raised earlier this year, according to TechCrunch.
The startup was founded in 2025 by Wei Lyu, Jason Chen and Hanying Hu. Lyu and Chen are former Meta Reality Labs employees. Earlier investors include Lightspeed and South Park Commons.
The company's first device is a pendant that can also be worn as a bracelet. The pendant weighs around eight grams and its battery lasts up to three days on a single charge. The form factor puts the device in a small, body-worn category where the microphone sits close to the wearer's mouth.
The central design claim concerns audio capture. Nirva says the device is designed to listen only to the wearer's own speech and to filter out the voices of other people around it. To make that work, users record snippets of their voice during onboarding, which the company uses to build its model. The model is therefore personalised to each wearer, and the enrollment step is a required part of setup rather than an optional calibration.
On data handling, Nirva by default does not keep audio data or transcripts after it processes conversations. That default sets the company's baseline position on retention.
In my view, the two privacy questions here are separate, and the announcement addresses only one of them. Not retaining audio or transcripts limits what exists on a server after a conversation ends. The onboarding voice samples are a different asset. They are a persistent, speaker-specific model input, and how long they are held, where they are processed and who can access them are the questions an enterprise buyer or a privacy-conscious user will want answered before trusting the device.
The broader context is a product category that has tried to solve bystander capture for some time. Always-on recording devices raise consent problems for everyone within earshot, not only for the person wearing the device. A pendant that tries to isolate its wearer's speech and discard other voices by design changes that equation, at least in principle. Whether the filtering holds up in a loud restaurant, a crowded train or a conversation with several people speaking at once is the technical test the announcement does not yet settle, and it is the one that will determine whether the design works outside a demonstration.
If the filtering performs as described, the practical gain is narrow but real: a body-worn assistant for note-taking, memory aids or meeting recall that does not sweep up the conversations of people who never agreed to be captured. That kind of restraint is the less common design choice in this category, and it is the part of the announcement worth watching as the product moves from funding news to hardware in users' hands.
The $25 million round is an announcement. What the announcement establishes is a specific set of design commitments (wearer-only listening, personalised enrollment, no default retention) that the company will need to demonstrate in deployment.
