Nadia, a 12-year-old seventh grader in New Orleans, was struggling with math. So much so that she was at risk of her school placing her in a slower math track.
While visiting her older cousin and his wife in Boston, she explained her plight. Her cousin, a hedge fund analyst with multiple STEM degrees, offered to work with her and get her back on track.
He tutored Nadia remotely, mostly via telephone, and using Yahoo! Messenger and its Doodle notepad and image-sharing program. Nadia responded well to the tutoring and thrived, and soon a dozen or so more cousins were seeking tutoring.
To manage the increased demand more efficiently, he built a personal website where he could post practice problems. A couple of years later, a friend suggested he start posting tutorial videos on YouTube.
Once the videos were public, they began to reach an audience well beyond just family members, and were soon being viewed by tens of thousands of people each month.
