Once upon a time, enterprises with charitable missions were considered not to be on the forefront of technology, the Internet and social media, but these tech-savvy social businesses show how many groups are on the cutting-edge of both positive change and the tech industry.

It's no surprise that technology (and with the help of Internet tools like social media) can contribute to solving social problems. This list ranges from interesting websites that track the consumer chain to innovative LED lights that are meant to replace dangerous kerosene lamps in places like Rwanda, where they have become ubiquitous.

From articles like "African Abuse Apps" and "Purpose-Driven IT Companies" to showcases of "Design-Focused LED Lanterns," these tech-savvy social businesses show you the best of charitable initiatives and technological innovation.
