BLOOMBERG - Apr 9 - Clubhouse, the buzzy audio-based social network, is in talks to raise funding from investors in a round valuing the business at ~$4B. A deal at that price would quadruple its value from January and would reflect the astronomical expectations investors have for the app. It's unclear how much Clubhouse is seeking to raise or which investors are participating. Paul Davison and Rohan Seth started Alpha Exploration, the startup behind Clubhouse. The app lets users host their own online radio shows. Listeners can tune in to hear interviews or panel discussions and ask to participate in live chats.
