Cynthia Breazeal has never considered herself a woman entrepreneur. An entrepreneur? Yes. A leader? Certainly. But gender really has never come into play as she expanded her company Jibo, the maker of the world’s first family robot.

Still, today is Women’s Entrepreneur Day, a global movement to celebrate and support female founders and shed light on some of their challenges. So Fortune interviewed Breazeal, as well as Susan Coelius Keplinger, the co-founder of online ad platform Triggit, about their experiences building their respective companies from scratch. Both women are part of Fortune’s 2014 class of Most Promising Entrepreneurs.
