The beta version of the audio app is currently invite-only, but its exclusivity has generated a lot of public interest.

The audio chat app Clubhouse is built for two types of people: the talkers and the listeners. Tesla founder Elon Musk is a talker. So is Facebook’s Mark Zuckerberg. Robinhood’s Vlad Tenev is a talker, as are many other influential Silicon Valley figures, like investors Ben Horowitz and Marc Andreessen, who have staked millions of dollars into Clubhouse’s success. A regular user can be a talker too, although there’s no promise anyone (besides a few friends) will show up and stick around.
