These types of businesses are very much startups, but have a more traditional philosophy and generally plan to stick around for longer than a few years. I'd say such businesses are often a lot riskier for the owners as they're generally risking their own money and time to get it developed rather than someone else's money. Spending someone else's money is not risky at all. Failure in a silicon valley startup isn't a real loss: it's expected.
The people who venture out on their own and take their own risk with their own capital and time should be applauded for trying to create sustainable businesses that might be beneficial to the wider economy and society rather than creating ones that try to dominate a market for a couple of years and then almost inevitably fade out (as most startups do both before and even after IPO), not really adding much to the economy or society at all, while, of course, screaming the obligatory "I will change the world" mantra. In fact, it's this idiotic mantra and the lies one must tell oneself to actually believe it that turns off a lot of great talent form the silicon valley startup version of a business. Most smart people can eventually see through such simple, repeated, dogmatic ideas easily, and don't like to be associated with the brainwashed masses for whom these ideas are reality.
