The story

In October 2012, GWI surprised social media analysts and commentators by claiming that Twitter and Facebook had big followings in China and Vietnam (later lift the ban on Facebook) – countries where those social networks are blocked by their respective governments. The story was picked up by various news outlets including Huffington Post, Bloomberg, and the Financial Times, where the rise of VPN has been attributed as the primary enabler for Chinese internet users circumventing website blocks. Almost a decade after the company was founded, and with customers including Google, Spotify, WPP and Omnicom Group, it closed its first round of series A funding in 2018. The company claims to have raised $180M series B funding in February 2022, and was valued at $850M.
