Businesses Only a Woman Could Start
Alexa von Tobel, LearnVest
Realizing that women were not always taught to control their personal finances, von Tobel launched LearnVest in 2009. It's a website that helps women manage money in creative ways, using tools and apps. The Harvard-grad led the company to raise $25 million in funding from Accel Partners, and LearnVest now has around one million women users.
