Chumz is proposing a virtual marketplace that allows college students to buy, sell, and rent textbooks directly from each other. This allows students to negotiate prices and control the cost of their textbooks for the first time. Currently, textbook resell and buyback rates are extremely low and fixed by bookstores. The marketplace aims to disrupt this by facilitating more profitable student-to-student transactions and eliminating interference from bookstores. Students can list textbooks at their own prices, while buyers have visibility into current market prices during negotiations. Chumz plans to generate revenue through small commission fees from sellers and a verification fee from buyers.
