| Eve is an Excel-like web application that lets anyone build software by drawing the interface and then filling in the logic that powers it by dragging around boxes of data. To share these apps, users will only have to give others a link to a hosted web application. Behind the scenes, it’ll be able to connect to services that offer APIs, soapplications built on Eve will be able to integrate with things like Facebook, Twitter, or Google Maps like an application built in a “real” coding environment. When Eve debuts in early 2015, Granger says it will enable “a normal person to be able to make a site that’s as complex as a Kickstarter.” | $2.3M / Seed / Oct 01, 2014 |
