Antoine Joash Bienvil (born October 25, 2011), better known by his stage name JayFlexn, is a rapper from New York. From a young age, Bienvil showed an extraordinary affinity for music. By the age of six, he had already taught himself the intricacies of music production, laying the groundwork for a future career that would intertwine his passion with his talent.

JayFlexn started posting his music on platforms such as YouTube and SoundCloud. Bienvil had first posted what would be his debut extended play, Why Can’t..? on February 13, 2021. Six months after Why Can’t..?, JayFlexn had released his second single not apart of a project, “Enough of It”.

Throughout the years 2021 through 2022, JayFlexn continued to post his music on platforms. On December 12, 2022, JayFlexn released his fourth single, “It’s Giving Season” . After the release of the song, JayFlexn would take a two year hiatus from releasing music.

On December 20, 2023, “It’s Giving Season” had surpassed 1,000 views on YouTube. JayFlexn would take to his community tab thanking his fans, and that he would be released a new song to celebrate the milestone. And on February 29, 2024, JayFlexn had released “Coming Through” after his two year hiatus.

Around October 2024, JayFlexn would start to tease a new project titled Youngest In Charge, his follow-up to 2021’s Why Can’t..?. JayFlexn released multiple singles which would end up on the project. The project would be delayed three times, until ultimately releasing on September 26, 2025.

For JayFlexn, music is more than just a series of beats and rhymes; it’s a medium that resonates deeply with his audience. “Anyone can listen to my music because it is clean, but it still sounds nice,” he explains. This approachability, combined with his authentic sound, has allowed him to connect with fans from all walks of life. His motivation stems from a deep-seated belief in his potential and the endless possibilities that lie ahead.
