WeChat's operator, Tencent, has an office in Palo Alto, CA. They're hiring. But WeChat seems to be run separately from Tencent, as the Wexin group.
Most WeChat and Tencent services are available in English, but so far Tencent hasn't tried to take on Facebook directly in the US.<p>WeChat is more than an "app". It's a mobile OS/browser which can run other services.[1] WeChat calls those services "official accounts". Once activated, they can send notifications and participate in payment systems. So, rather than having an app for each service, most services work through WeChat's standardized interface.<p>Last year, WeChat kicked off Uber's official accounts for what they claimed was a TOS violation. This was a big hit for Uber. Customers could no longer call a Uber from WeChat. Didi's official accounts remained live, as did those of other taxi companies. WeChat is an investor in Didi. This may be part of why Uber caved and sold out to Didi.<p>When augmented reality comes, it might look a lot like WeChat.<p>[1] <a href="http://a16z.com/2015/08/06/wechat-china-mobile-first/" rel="nofollow">http://a16z.com/2015/08/06/wechat-china-mobile-first/</a>
