Journalism.co.uk reported last year that Ongo had already been offered multi-million dollar funding from Gannett Company, the New York Times Company and The Washington Post, prior to its launch.
Today Ongo announced the list of titles available on the platform at launch, which also includes Slate, the Boston Globe and selected content from the Financial Times.
The subscription service provides a single web interface where full articles are delivered alongside customisation features, as well as curated content by an editorial team.
According to a release from Ongo, stories can be searched for both within and outside of publications subscribed to, and saved in a 'clippings' section. There is also a My Topics feature which enables subscribers to personalise a 'daily dose' of news based on selected sections or keywords.
"Ongo is launching a news service that puts readers first, and will continue to do so by adding new publications and features," Alex Kazim, Ongo Inc.'s founder and chief executive officer said in the release.
"Ongo redefines readability and provides the most sought-after content from top sources. Our smart tools ensure that readers get the news they need while our editorial team spotlights the interesting, informative and entertaining stories that shouldn't be missed."
The service also offers invitation-only 'clubs' where subscribers can create discussion groups.
Subscription to Ongo costs $6.99 a month which allows subscribers to add one title of their choice from a list of selected publications. Additional titles can then be added to the subscriber's account, starting at 99 cents a month.
Ongo is offering a free one-month trial to those who set up a subscription at launch and a free 'day pass' for one day of access.
