In addition to meeting Sultan, Shay was introduced to Cecil Hammond of Flytime Promotions. Hammond signed her to his record label Flytime Music and decided to launch her solo career in Nigeria.

On 11 August 2011, she released "Loving Your Way" and "No Le Le", two promotional singles that helped launched her singing career in Nigeria.

Her music career took an upswing when she signed her first ever record deal with No Apology, a record company affiliated with George Martin (commonly referred to as the "Fifth Beatle"). In 2006, Shay formed a girl band in the UK called Boadicea; they were managed by Ron Tom, the founder and manager of All Saints and Sugababes. The band separated after two years, and Shay decided to partake in the From Above UK singing audition. After the conclusion of the audition, she emerged as the lead vocalist for the now defunct girl group From Above. The group inked a record deal with Mathew Knowles' management company after performing for him. They were taken to Houston to undergo energetic vocal and dance trainings. The group supported Beyoncé while she was in the UK for her I Am... World Tour. They presented an award at the 2011 MTV Europe Music Awards and had their own MTV reality show called Breaking From Above, which aired in over 166 countries around the world. The group later disassembled and Shay had an opportunity to continue her management deal with Mathew Knowles, as well as secure a recording contract with Sony. Instead, she made a decision to join Flytime Music after getting an offer from them. Shay has worked with a number of musicians, including Justin Timberlake, Brian Michael Cox, Darey, Bilal, Michelle Williams, Chip, Rob Knoxx, H-Money, and Cameron Wallace.
