Offline augments live events using innovative mobile technology. In three years, tens of millions of people on six continents have shared these unique experiences with us.

Combining ultrasonic audio, Bluetooth, and traditional 4G networks, our platform reaches mobile devices as quickly and effectively as possible. Our app platform uses light, sound, notifications, and targeted messaging to immerse event attendees in their surroundings.

We are a team of 5 (mostly engineers) based in Brooklyn, NY.
