I'm David Polberger, an entrepreneur based in Lund, Sweden.
We make Calcapp, which is "Excel for apps," a web service allowing anyone with spreadsheet experience to build number-crunching line-of-business apps. Spreadsheets tend to break easily when users change the wrong cells and don't work well on mobile devices. Apps, of course, are not afflicted with those problems and we'd like to make them as easy to create as possible.
