Our take

Reddit is a website that facilitates thousands of message board communities, known as subreddits, with an aim to promote authentic human connection. There are more than 100,000 communities on Reddit, covering everything, from food, entertainment, sports, and books, to more niche topics that cater for very specific audiences.

The simple platform is used by more than 52 million people a day and attracts over 50 billion monthly views. While these are impressive numbers, they do pale in comparison with social media giants Facebook and Twitter, however, Reddit distinguishes itself by providing easy-to-find communities for a truly endless range of topics.

Reddit makes money through advertising as well as offering a premium ad-free membership plan. The company has enjoyed continuous user & revenue growth, acquisitions by Conde Nast in 2006 and Advance in 2011, and plans to launch an IPO bid in 2024.
