Back in 2018, I began working with Kristin, the founder of One Stop Teacher Shop. A former teacher and homeschooler, Kristin had built an incredibly successful business on Teachers Pay Teachers (TPT), becoming one of the platform’s top sellers and generating over $1M per year in revenue. While thriving, her entire income depended on a third-party marketplace. She knew that if TPT ever changed its rules or shut down, her business could collapse overnight.
