WHAT WE DO Freedom to face the world

That's Nain's corporate mission.
We hope to build a world where humans come first. To do that,
we are leveraging technology to get back those precious moments that technology has taken from us.


Since the invention of technology, people have spent more and more of their time operating the things around them. We believe that the next innovation will change that: instead of operating technology, technology will enable us to live more humanly. AI, IoT and wearable technologies will be key to that change.

Precious time, precious people

We envision a world of people who spend their time making connections and creating new things — a world where people are free to study, to draw and to imagine. Whether it is your own time or time spent with friends, every moment should be precious.

A more connected world

Free from the stress of looking at screens, people will be able to move more freely and efficiently. Connecting people with new worlds will create more opportunities to encounter new people, new scenery and new ideas.

Hearable technology

We develop next-generation wearable technology: earphones that allow users to listen to information. We are committed to developing devices that make people feel like they have a sophisticated friend by their side at all times.
