The story
DevHD's first project was Streets. It aggregates updates from a variety of online sources and is the basis of Feedly. Originally called Feeddo, Feedly was first released as a web extension before moving onto mobile platforms.
On March 15, 2013, Feedly announced 500,000 new users in 48 hours due to the closure announcement of Google Reader. By April 2, 2013, the total number of new users was up to 3 million. At the end of May 2013, the total user number was up to 12 million. In 2018, Feedly had 14 million registered users.
Denial-of-service attacks
On June 11–13, 2014, Feedly suffered denial-of-service attacks that prevented users from accessing their information. The attackers demanded ransom from Feedly, which the company refused to pay.
