In 2005, Catherine Cook and her brother, Dave, were flipping through their high school yearbook to see if they recognized anyone. While looking through it, Catherine thought of putting the whole yearbook online. This idea sparked a multi-million-dollar company in the years to come – and Catherine was only fourteen!

After coming up with the initial idea, Catherine contacted her oldest brother, Geoff, who was a sophomore at Harvard University. Geoff Cook was already on the road to making hundreds of thousands of dollars off his two websites EssayEdge.com & ResumeEdge.com, when his younger sister first told him of the idea. He immediately invested $250,000 into her idea and they began working with developers in India to bring the website to life.

Within one week of launching the site, Catherine & Geoff had 400 people with accounts – and it was confined to their hometown of New Hope, PA. Catherine would wear creative shirts that said things like, “Are you the prettiest girl in school? How about the dumbest? Find out!” By 2006, the website had over 1 million users. It continued to grow throughout the following years until, in 2010, it entered the top 25 most-visited websites.

In 2011, myYearbook merged with the Quepasa Corporation for over $100 million. One year later, they renamed the company to MeetMe. MeetMe still keeps some of the same features that made myYearbook so popular, but it now offers online chatting and connections with other people.

Katherine’s simple idea turned into a multi-million-dollar venture, something she says she definitely did not ever expect. myYearbook is a great example of the possibilities that can arise from a unique idea.
