Viber builds and operates a free calling and messaging application used by hundreds of millions of people each month. The engineering work spans messaging technology, real-time voice and video calling, end-to-end encryption, mobile application development, file and media sharing, and group communication platforms. The core application supports messages, photos, videos, stickers and files, as well as high-quality voice and video calls, with group chats accommodating up to 250 members.
Privacy is a structural feature of the product rather than an add-on. All one-to-one calls, personal chats and group chats are protected by built-in end-to-end encryption. Beyond the core app, the company develops Viber Out, an international calling service that connects users to non-Viber numbers abroad, and Communities and Channels, features for interest-based groups and broadcasts.
Viber is a subsidiary of Rakuten Group, a global e-commerce and financial services company. The company is headquartered in Luxembourg, was founded in Israel and maintains development centres in Israel and Belarus. It operates across the telecommunications, consumer messaging and mobile applications sectors, and describes its purpose as connecting people for free regardless of who they are or where they are from.
