Alfredo Brillembourg founded the Urban-Think Tank (U-TT) collective in 1998 as an informal multi-disciplinary research group in his home in Altamira, Caracas. In 2001, Brillembourg invited Hubert Klumpner to co-found the U-TT NGO and later in 2007 to co-found the U-TT company in Caracas, Venezuela. Brillembourg and Klumpner continued their partnership in Zürich, which lasted until 2019. In 2020, U-TT Norway was established by Brillembourg to expand socially and environmentally sustainable projects with Scandinavian funding and new partners of the global U-TT Design Group.
