Happy Hearts Fund (HHF), founded in 2005 by Czech supermodel Petra Nemcova after her 2004 Indian Ocean Tsunami experience in Thailand, is dedicated to rapidly and safely rebuilding schools after natural disasters. In 2006, HHF extended its mission to Indonesia following the Yogyakarta earthquake. In 2013, Happy Hearts Indonesia (Yayasan Hati Gembira Indonesia) was established, with a national school rebuilding focus. In 2016, HHF expanded to East Nusa Tenggara (NTT), concentrating on education and poverty reduction in Sumba, Flores, and Timor, including the successful #IAMCHANGE campaign that rebuilt 200 schools.
