Building the future
of private voice.
We believe voice is the fastest, most expressive interface between humans and intelligent systems. But you shouldn't have to surrender your privacy every time you speak in public.
Why we started
Today, hundreds of millions of knowledge workers operate from coffee shops, airport waiting lounges, commuter trains, and open-plan shared workspaces. We take high-stakes negotiations, conduct sensitive client consultations, and speak to generative voice models.
Yet, speaking aloud in public creates friction: strangers overhear your private details, and your voice disturbs people working nearby.
We created NullWave to solve this dilemma at the acoustic foundation. NullWave is a lightweight, comfortable wearable that traps and absorbs speech sound waves inside the mask. You can speak naturally without anyone around you hearing what you say.
