Ahn studied medicine at the
Imperial College London. She became angry at the
feminine hygiene market and more concerned by environmental issues. Frustrated by the impact of sanitary pads on the environment, she founded Planera during her final year of medical school. She competed in entrepreneurial competitions at
Imperial College London, securing financial support, mentorship, and sponsors. Ahn has said that her biggest advice to budding entrepreneurs is to do consumer testing and validation: extensive in-house testing proved insufficient. == Fluus ==
