Sunrise, the startup behind the acclaimed email service and iOS calendar app of the same name, has raised a $2.2 million seed round led by Resolute and NextView Ventures, with participation from well-known angels like Dave Morin, Loic Le Meur and Hunter Walk. Sunrise was founded as a bootstrapped startup by New York-based Pierre Valade and Jeremy Le Van, who left jobs at Foursquare to launch a daily email service that augmented your personal calendar with information from your social networks (think ‘Rapportive for calendars’). This was followed in February this year by the launch of the iOS app, which we described as “powerful, beautiful” and “supremely useful.” Valade tells us that the funding will be used to continue to “build the best calendar app.” In addition to further development of the iOS version (including iCloud support), Android and Windows apps are on the roadmap – and not just on mobile, a desktop version is planned too.
