Mxit (pronounced "mix it") is a free instant messaging application developed by Mxit (Pty) Ltd. in South Africa that runs on over 8,000 devices, including feature phones, Android, BlackBerry, iPhone, iPad, Windows Phone and tablets.
According to a study by consultancy World Wide Worx, Mxit had 7.4 million monthly active subscribers in July 2013, of which 6.3 million were South Africans.
The company announced its closure in a statement on October 23, 2015. All of the company's intellectual property and technology assets were donated to The Reach Trust, an independent public benefit organisation. The organisational changes did not affect the mobile social network, and users are still able to access and use all its services.
