Students Make Money With Their Notes on Flashnotes

Studying pays. No really, it does. Founded by David Petruziello, Steven Maggs, and Michael Matousek, Flashnotes is an online marketplace where college students can buy and sell notes. So if you've been a diligent note-taker, this is your chance to earn some extra money with what you already have. You set your own price (the average is about $8 per note) and keep up to 80 percent of every sale. If you haven't been taking notes, Flashnotes may still prove to be a valuable resource for you, as 65 percent of students who have bought materials from the site report seeing an improvement in their GPA.

Flashnotes is currently available in 75 schools across America. Recently, the Boston-based startup closed a seed round that raised $1.8 million from Softbank Capital, Atlas Venture, Michael Lazerow, and other angel investors. The funds will go into further research and rolling out the system nationwide.
