Company Summary

Vozero will offer a social network for public short voice messages. It's like Twitter, but for spoken messages. This allows for the possibility of access via feature phones, which still represent the majority of all cellphones in Brazil. This will also unlock new revenue streams for partner carriers without the deployment of new infrastructure. Vozero is partnering with Vivo to develop its product.
