Flattered was founded in Stockholm, Sweden, in the spring of 2013. The idea behind the company grew out of the combined vision of its co-founders, Isabella Löwengrip and Hanna Kwiatkowska Thisner.
Both Isabella and Hanna had noticed that there was something missing from the market. For Isabella, it was a feminine, stylish, yet comfortable indoor slipper. For Hanna it was the perfectly created ballet flat. During their very first meeting, they decided to merge these two ideas and fill the gap together, and this was the beginning of Flattered. Before long, Gustav and Pingis got on board as well, to contribute their expertise to the development of the concept. By the autumn of 2013, Flattered had launched its first product, a ballet flat meant for indoor use.
