Sunrise Calendar

Sunrise is a discontinued electronic calendar application for mobile and desktop. The service was launched in 2013 by designers Pierre Valade and Jeremy Le Van. In October 2015, Microsoft announced that they had merged the Sunrise Calendar team into the larger Microsoft Outlook team where they will work closely with the Microsoft Outlook Mobile service.
History.
The first iteration of Sunrise launched in 2012 and was a daily email digest of appointments, events and birthdays. 
Sunrise was launched initially as an iPhone application on February 19, 2013.
In June 2013, Sunrise raised $2.2 million in venture funding from Resolute.vc, NextView Ventures, Lerer Hippeau Ventures, SV Angel, and other angel investment firms like Loïc Le Meur, Dave Morin, Fabrice Grinda.
In May 2014, Sunrise launched on Android as well as on the web via a web application.

On February 11, 2015, Sunrise Atelier, Inc. was acquired by Microsoft for US$100 million. 
On October 28, 2015, Microsoft announced that Sunrise would be discontinued, and its functionality merged into Outlook Mobile. Microsoft later stated that the app would permanently cease functioning on August 31, 2016, but the shutdown was delayed to September 13, 2016 to coincide with an update to Outlook Mobile that incorporates aspects of Sunrise into its calendar interface.
