People who have bought a Matter article can now save it to Pocket and then access it via the app, which offers the ability to read offline.
Matter joins other paywalled sites, including the Economist, Financial Times and New York Times, which have similar deals with Pocket (formerly Read It Later), allowing subscribers to those sites to save articles and read them via the app.
An announcement post on the Pocket blog explains this is done via the 'site subscription' feature.
Matter published its first article three weeks ago. It is 7,800-word investigation into people who desire to be amputees, tracking one person as they go through the illegal operation of having a leg removed.
The new type of publishing venture, which will publish one or two 5,000 to 10,000-word articles a month charged at $0.99 and accessed via the Matter website, Kindle and tablets, was set up by Jim Giles and Bobbie Johnson, who is also European editor of technology site GigaOM.
They raised seed funding via Kickstarter, originally aiming for $50,000, but ended up attracting a total investment of £140,000.
Bobbie Johnson will be speaking about Matter at this week's news:rewired conference.
