HTML was created in Switzerland. Linux in Finland. Not sure what "software" companies are for you. Google? Well, China has enough Internet counterparts (Tencent, Wechat, Alibaba etc.). Softbank (Japan) just bought ARM (UK). Regarding "software" companies like Microsoft, SAP (DE) is quite a decent size. Nokia (Fi) was once leading edge too. Sure you have not heard about Skype and Transferwise, but they do exist. Maybe you should come out of your little bubble once in a while?
