Jüngst invented the product with co-founder Tim Jäger as a student project at University of Schwäbisch Gmünd in Germany. She’s now the company’s chief evangelist and managing director.

Air Up just launched in the United States last month, but it’s found success in every other country where it has done business. The first product run in Germany sold out in two months, Jüngst said. In addition to the U.S., Air Up is in nine European markets, and the company became profitable in 2021. Revenues have been on a steep upward trajectory, she said: $2 million in its first six months, then $20 million in 2020, and $90 million in 2021. The company has raised a total of $67.9 million, according to Crunchbase, with investors including PepsiCo, Ashton Kutcher and Mila Kunis.
