Forget TikTok. Audio-based Clubhouse is social media's next big thing

 The next killer smartphone app has arrived — and it offers the potential to transform how we communicate, share knowledge and even make new friends.

I am talking about voice-and-audio-based social networking startup Clubhouse. Its platform enables users to drop in and out of ephemeral chat rooms and take part in a range of gatherings, from small "water-cooler" type conversations to larger discussions featuring expert panels, often attended by thousands of listeners. Since its launch last March, Clubhouse has increasingly become a cultural phenomenon, attracting politicians, celebrities and experts from all walks of life. With its success and prominent backing, it may now be poised to upend the entire social media space.

Clubhouse's latest figures reveal how quickly it is growing. During a weekly town hall event on Sunday, co-founder Paul Davison said the app's weekly active user base had doubled to 2 million over the last couple of weeks. He also announced the startup had raised another investment round led by venture capital firm Andreessen Horowitz, adding it now has more than 180 investors. While he didn't offer any specifics, The Information reported on Friday that Clubhouse was getting interest at a $1 billion valuation. If true, that means the company's value has risen by a factor of 10 since its earlier Series A round last May, also led by Andreessen Horowitz.

Something special is happening inside the Clubhouse community. Call it the power of the voice — and it's what separates Clubhouse from other platforms. A short back-and-forth live conversation, with its nuance and tone, can build closer relationships more quickly than dozens of written posts and text messages sent through more established social networks such as Facebook and Twitter. Since I joined Clubhouse last summer, I met and became friends with professors, filmmakers, artists, engineers and more from places all over the world. It has been intoxicating listening to people's life stories and absorbing their knowledge and experience, from learning how a streaming video executive greenlights projects to getting expert political analysis on the latest breaking news. It has easily become one of my favorite pastimes.
