Microsoft has acquired SwiftKey, a company that built an intuitive keyboard for iOS and Android (but not Windows Phone) devices, according to a report today.

Microsoft paid around $250 million in the deal, which it is set to be announced later this week, according to the Financial Times.

Microsoft declined to comment.

The report of the deal follows a string of other acquisitions of modern apps, including Acompli, MileIQ, Sunrise, and Wunderlist.

SwiftKey announced a $17.5 million funding round in 2013. Investors included Accel Partners, Index Ventures, and Octopus Investments. The company started in 2008 and had offices in London, San Francisco, and Seoul.

The SwiftKey keyboard is installed on 300 million mobile devices and supports 89 languages, according to the company’s website. OnePlus, Samsung, and Xiaomi have partnered with SwiftKey in the past, the site says.

Many of SwiftKey’s 150-plus employees will join Microsoft Research, the Financial Times reported.

Update on February 3: Microsoft has confirmed the acquisition.
