Stonewash Ltd.

Stonewash Ltd. was a digital magazine distribution company with offices in London and New York. The company built iOS, Android and Windows 8 apps for magazine and newspaper publishers, as well as catalogs.

Company
The company was founded in 2009 by Daniel Sharp and Robert Grainger as a spin-off from DD&AG Ltd, a specialist London-based digital agency. Their product allows publishers to take existing PDFs and convert these to digital editions within native apps, and Stonewash were one of the first businesses within this field.

Initially the product was made available for iPhone, but was expanded to iPad in May 2010. In January 2012 Stonewash were invited by Microsoft to build the first magazine app framework for Windows 8 and were the first developers to release magazines to the consumer preview version of Windows 8 in April 2012.

Stonewash was acquired by Paperlit in early 2016.
