I think the social safety net is definitely a part of it, yes. But after working for a couple years at different startups in Stockholm I can say that another big factor is that most Swedish founders are either rich themselves, or their parents are, or they are very well connected. They don’t see themselves this way of course, they think they are building everything from scratch, but this does tend to be the case from my experience.
I think it is becoming more common. In the early days it seems like there were more of a mix between rich drop outs and poor enthusiasts. Today, especially with the housing market, it seems like there are a lot more 'fake' companies. It used to be that if you came from a wealth family and didn't know what to do you started a public relations, event or media company to pretend that you were doing something. Today that is a "technology startup". Most of which are second or third tier companies in the sense of global reach. While much of the success of Swedish startups come from ending up being first tier companies. Maybe part of that was that Sweden sort of experienced the dot com bubble, which meant that there was less room for phonies for a while.
