In late 2018, Ingmar Rentzhog, founder of the non-profit We Don't Have Time Foundation (WDHT), recruited Thunberg to become an unpaid youth advisor and used Thunberg's name and image without her knowledge or permission to raise millions for WDHT's for-profit subsidiary We Don't Have Time AB, of which Rentzhog is CEO.
