Born in Lagos state Nigeria, Simi, a mass communications graduate, is no stranger to the Nigerian music industry. She wrote her very first tune at the age of 10 and started out singing and dancing in her early teens as a member of the teenage church choir. Eventually, she went on to launch her debut album in 2008, which was produced by Samklef. The album spawned hits such as Ara Ile, Ogaju, Iya Temi, to name a few. She started off as gospel with the songs in her debut album.
In 2011, she met the talented producer/songwriter (Oscar Heman-Ackah) and they both connected musically. However, it wasn't until 2013 that she officially signed a production contract with Oscar Music Production, after which they both nurtured and created a fresh and genius direction to her sound, style and music in its entirety.
