Deborah Oluwaseyi Joshua, professionally known as Șèyí and formerly as Seyi Shay, is a Nigerian-born artist whose career has developed across both the United Kingdom and Nigeria. Born on 21 December 1985 in Tottenham, London, she was raised in a household where music and religious activities formed part of her early environment.
Her background reflects a blend of British and Nigerian influences. She maintained early ties to Nigeria through regular visits and schooling, attending Junior Strides Academy in Lagos and later Command Day Secondary School in Ikeja. She subsequently returned to the United Kingdom, where she completed a degree in Music Business Management at the University of East London.
Her initial exposure to music came through church participation and family influences. Over time, this developed into professional involvement, including early work within the UK music industry. She secured a recording contract with No Apologies, a label associated with producer George Martin, and later became part of the girl group Boadicea. Following the group’s dissolution, she joined From Above, a group formed through a televised music competition and later signed to Music World Entertainment, owned by Mathew Knowles. The group underwent training and participated in live performances, including appearances linked to international tours.
In addition to performing, Șèyí has been involved in songwriting and production, contributing to various projects across music and media. Her credits include work on soundtracks, collaborations with multiple artists, and contributions to recorded music projects in both the UK and Nigerian markets.
Her solo career progressed with the release of a debut studio album in 2015, followed by the extended play project Electric Package in 2018. In the same year, she appeared in a lead role in the Nigerian film, Lara and the Beat. Subsequent releases included collaborations and a second studio album, Big Girl, in 2021.
After 2021, her public musical output reduced for a period, during which her focus shifted toward personal priorities. She later returned with new material in 2025 and introduced the stage name Șèyí, reflecting a change in artistic presentation.
Her career spans multiple roles, including recording artist, songwriter, and performer, with activities distributed across different phases and markets. The recent rebranding marks a continuation of her presence in the music industry, following over a decade of sustained involvement.
