Apparently there are some entrepreneurs out there who are more interested in doing good than they are making money. While we don't know any of them, apparently BusinessWeek does. The mag has a feature on the rise in popularity of start-ups that intend to serve some social good (think green business), and the particular struggles those businesses face when it comes to getting funding. The problem, they say, is that these start-ups, typically run by young entrepreneurs, have business plans with "dueling bottom lines—social and financial."

But the article misses the point. It's not that socially-responsible businesses can't get funding. In fact, as any VC in the valley will tell you, do-good green technology is incredibly hot right now. To wit: thin film solar technology start-ups scored more than $700 million in funding this summer alone. We're going to sound cynical here, but the real issue seems to be that investors don't want to write big checks to overly idealistic entrepreneurs who are fresh out of b-school. To a large extent, that makes sense. Most of these kids don't have real-world experience outside the classroom- and if you've spent time listening to the lofty talk in a college seminar recently, you know why that's a scary thought. In that context it's understandable why the words "I just want to change the world with my start-up," might give some investors the hives.

Nonetheless, some young entrepreneurs obviously know what they're doing. Mark Zuckerberg, anyone?

Would you fund someone under 30 who had a great idea?
