Catarina Dahlin’s business idea was born out of the need to sleep well, no matter the weather. Working with Empa and Hochschule Luzern on a new, patented technology, she looked to fill a gap in the market for sleepwear that can adjust to your body temperature. The co-founder and CEO of Dagsmejan talks about luring investors, the importance of being sustainable, Swiss-made, and about expanding beyond clothes.
