Isaiah Faber (born March 31, 1999), known professionally as Powfu, is a Canadian rapper, singer, songwriter, and record producer. He is the son of Dave Faber from the band Faber Drive. He amassed popularity following the release of his first charting single, "Death Bed (Coffee for Your Head)", featuring Beabadoobee, which peaked at number 23 on the Billboard Hot 100.

In February 2020, he released the song "Death Bed (Coffee for Your Head)", which featured a sample of Beabadoobee's debut single "Coffee". The single has received over 1 billion streams on Spotify as of June 2021, and peaked at number 23 on the Billboard Hot 100 after amassing popularity through the video-sharing app TikTok. After re-releasing the single a year after, Powfu signed with Columbia Records in the US, in conjunction with Robots + Humans in the United Kingdom. The song appeared on the EP Poems of the Past, which was released on May 29, 2020.

On December 2, 2022, Powfu released his first full-length album, surrounded by hounds and serpents, which included a cover of Taylor Swift's "Mine". In an interview with Billboard, he stated that this album title describes his search to spot "people who are fake or only want [him] for the wrong reasons".

Powfu has released a special new song with fellow lo-fi artists Ouse and Snøw. The song arrives alongside an official video directed by longtime collaborator Aze. The song will be featured on the upcoming Flooding the Gates EP -a full collection of songs written and recorded by the 3 artists on the road during Powfu’s Flooding the GatesTour in June 2022.
