Since 2003 Kasper and Thomas have worked together, from their studio in Copenhagen, and their first designs the NOSY desk lamp for Lightyears was exposed in 2008. They have mainly worked with lighting since they teamed up. Kasper Salto and Thomas Sigsgaard have chosen the "behaviour" concept, because the finished lamps always appear to have their own personal characteristics. For Kasper Salto and Thomas Sigsgaard it is neither professionally nor personally satisfying to build on an already well known style.. Therefore, from the beginning, they have wiped the slate clean and worked intensively with the development process itself to create a design that is unique and well thought through, in every way.
