Sunrise

Microsoft adquirió Sunrise por $100M por su hermoso diseño de calendario — luego cerró Sunrise 12 meses después y lanzó Outlook Mobile con las mismas características

Error fatal: Sunrise built the most beautiful mobile calendar app. Raised $8M from Betaworks, Greylock. Microsoft acquired for $100M in February 2015. Microsoft planned to integrate Sunrise into Outlook. One year later, March 2016: Microsoft shut Sunrise and launched Outlook for iOS/Android (incorporating Sunrise features). Product was acquired and discontinued in 12 months.
