Roost enables push notifications for websites. With the decline of RSS and the death of services like Google Reader, Roost fills a vacuum for readers who want to stay engaged with their favorite websites. Roost enables readers to receive up to the minute, light touch reminders whenever their preferred web publishers post new content, but without crowding their inbox or overwhelming them with heavy messaging. Roost, in turn, allows web publishers to identify their most loyal readers and consistently create new interactions with them. Apart from Roost, desktop push notifications are too cost and resource prohibitive for publishers to integrate with their websites. Roost solves this problem. With the emergence of mobile apps, push notifications quickly became the preferred method of content consumption within apps. Roost is applying this communication channel to the web. Founded in 2009 as Notice Software, Roost began to earnestly pursue a mobile web push in 2012.
