As part of this special issue showcasing and celebrating women in technology, an issue in which seasoned technology leaders share their experience-based insights, we thought it was also worth honoring some younger women. And not simply remarkable up-and-coming technology leaders. We went looking for young women whose career thus far has involved leveraging technology for purposes beyond the creation of business value. Women whose professional work has had a positive ripple effect - a multiplier effect - through society. Women whose work is thus more than the sum of its parts and has an overall value that you might say represents those parts "squared." This somewhat subjective 30-squared list aims to recognize women at companies small and large (though many on the list are founders of a start-up) in a variety of industries and from around the world. We hope you find their work as inspiring as we did.
