Ruth B had initially gained popularity by posting six-second snippets of her singing on Vine; she was encouraged by her fans to write a full-length song, so she wrote "Lost Boy", which ended up being her first hit. The song entered the Top 100 of the iTunes chart "with no promotion", and B began receiving offers for recording contracts from various record labels. She signed to Columbia Records and shortly after began recording music for "The Intro." B stated in an interview with Rookie that being signed "felt really validating and cool that people in the business thought that I could do it, not just my friends and family."
