Hubbub is a voice-based social networking platform that allows users to listen to 30 second voice messages from other users, follow accounts, and comment by voice. It aims to combine social networking with everyday listening activities like driving to create a non-distracting experience. The platform utilizes voice authentication for security, voice command controls, audio search, and integrates external music streaming. The 12 person team plans to launch with a freemium model including advertising to enter the $10.4 billion social media market with this vacant voice-based niche.
