You are saying that it is special because of the clustering, so I am wondering what indicates that? If you look at Sweden or Israel it is fairly obvious that they are successful in at least half a dozen areas. You can trace the path from one area or company to the next.
In Sweden Markus Persson who made Minecraft used to work at King. Jacob de Geer of iZettle was the first employee at TradeDoubler, which was founded by Martin Lorentzon who would later be a founder of Spotify. Daniel Ek of Spotify used to work at another gaming company and of course the music industry is large in general. Zennström who started Skype used to work at Tele2, a telecom operator. Klarna was started with help from people from Bluetail, which used Erlang in turn made by Ericsson. Etc. Etc. (This is just off the top of my head and all these companies had large exits or were already established).
That is what a successful cluster is and what makes them hard to replicate. Without this dynamic it is just a bunch of companies next to each other. So why doesn't Switzerland seem to have that?
