Mary Fallon and co-founder Dori Graff were ahead of their time in 2014 when they launched Kidizen, an online resale marketplace for children’s clothing. The Minneapolis-based startup was positioned to take full advantage of a secondhand apparel boom driven by increased consumer interest in sustainable fashion. Coupled with an uptick in online commerce since the pandemic, Kidizen’s community of buyers and sellers is nearing 1 million members. With Fallon’s focus on brand strategy and innovation, this year, Kidizen started partnering with major brands like Tea Collection. Fallon serves as a mentor to other Minnesota entrepreneurs through programs such as BETA.
