Clubhouse is a mobile app that has taken the mobile marketplace by storm. What makes this mobile app so popular? The answer might be in its audio-only medium. Listeners can use it while they are at work, doing chores, or just walking around town. It frees up their hands to do other tasks and allows them to learn from Clubhouse without being distracted by pictures or videos on their screen. Startups can learn from Clubhouse because they took something old and made it new by changing the way people interact with audio and social media content.
