Huddl is a free group messaging app that allows users to communicate in private circles like friends and family or more openly like with coworkers and classmates. It aims to make sharing more comfortable by aligning conversations with real-life social groups rather than one public stream. Huddl launched with over 2,000 daily active users and differentiates itself from competitors by enabling various group types and integrating with other platforms through QR codes. The founding team has successful startup experience and Huddl has potential for viral growth through social sharing features.
