The inspiration for Mums Who came in early 2017 with a Facebook message about home organisation. After realising how much they had in common, Karlie and Rachael became great friends and together set up the Mums Who brand, starting with the Mums Who Organise Facebook group. The Mums Who Clean Facebook group was formed after many requests and quickly became their most popular group. Karlie and Rachael now have eleven Mums Who groups on Facebook, all providing safe, friendly and supportive communities where Australian women can share their ideas, strategies and hacks. Both small business owners based in Victoria, Karlie has three daughters and Rachael is a mother of two boys.
