Early life Glantz was raised in Deerfield, Illinois, a suburb of Chicago, Illinois. At the age of 8, Glantz saw his father playing guitar which inspired him to learn as well. He has two siblings: a younger brother, Brady, and a younger sister, Olivia. He is Jewish.

After high school, Glantz went to the University of Pennsylvania for engineering, but dropped out a year later to pursue music more seriously. Glantz then moved to Los Angeles to begin songwriting and producing for others and soon after he decided to write songs for himself and to pursue a career as an artist.

Career Alexander signed to Interscope in 2019. He released his first single "Dirty AF1s" in 2019 which made it to Spotify's New Music Friday playlist and was recognized as Apple Music's "Bop of the Week". After releasing five subsequent singles, his first EP I'm Sorry I Love You was released by Interscope in October 2019.

When describing his decision to go by Alexander 23, Alexander said, "I was born on the 23rd, I grew up in Chicago and saw Michael Jordan as a huge figure in basketball and was obsessed with him, and he wore number 23. Plus, I was 23 when I started writing these songs. I knew that I wanted to go by my real first name and I just thought I'd spice it up by adding number 23 at the end."

His second EP, Oh No, Not Again! was released on February 19, 2021, on Interscope Records.

In 2021, he played Dove Cameron's love interest in the official music video for her single, "LazyBaby".
