Industry leaders told her the idea would fail, but less than three years after launching GoldieBlox on Kickstarter, she has made significant strides in her quest to bridge the gender gap in STEM: she has launched massively successful viral videos, a Superbowl ad that brought mainstream awareness to her mission, an award-winning iOS app and GoldieBlox presence in more than 6,000 retail stores worldwide. Debbie has also recently been selected to join the Presidential Ambassadors for Global Entrepreneurship, a select group 'committed to helping develop the next generation of entrepreneurs around the world.'
