So I hadn't heard of Clubhouse before so I googled it. I didnt even click the link and Google told me;

> Clubhouse is an invitation-only audio-chat social networking app launched in 2020 by software developers Alpha Exploration Co. As of December 2020, it was valued at nearly $100 million. On January 21, 2021, the valuation hit one billion US dollars.

$100m to $1b value increase in a month? What happened?
