Amadeus Capital and Northzone have just joined hands with Peter Larsson (via Monterro Holdings) to acquire a majority stake in EPiServer.Stockholm-based EPiServer, a web CMS purveyor, significantly exceeds estimated industry growth of 13 percent per annum.CMS Watch points out this is a pretty ambitious series of changes for a company that only hired its first employee outside Sweden last year. But scaling in Scandinavia isn't as easy as one would hope. EPiServer's biggest competitor, reach-wise, is Sitecore. There's also Polopoly, I guess, but we haven't heard much about them since that pay-per-view blogging thing.The Amadeus/Northzone/Larsson transaction cost about US$ 23.5 million. Peter Larsson will be taking on the mantle of CEO.
