Alremaihi stepped in to run the Doha Film Institute in 2014 right after the government-funded entity, established to foster a film industry in Qatar, severed its ties with the Tribeca Film Institute and other Hollywood companies. Since then, it has redefined its mission and now operates a film fund primarily for Arab movies, an international festival for young filmmakers and the mentorship nonprofit Qumra, which blends festival, workshop and international co-production marketing elements. Alremaihi has turned the institute into a key source of funding and an incubator for Middle East creativity. More recently, DFI opened its grants program to TV and web series in an effort to foster serialized Arabic content. In 2019, seven DFI-supported films screened at the Cannes Film Festival.
