Mickey Factz attended Adlai E. Stevenson High School, which is known for being the high school of hip hop pioneer Afrika Bambaataa. The school is notable for delivering students of musical prowess.
Factz was exposed to music at an early age and his father would frequently rap to him. In return, he began reciting his very own rhymes, watching music videos, and studying the performances of his favorite music artists. After high school, Factz went to New York University School of Law where he dropped out to pursue music 
Mickey Factz did many freestyles over N.E.R.D instrumentals on In Search of N*E*R*D (2006) in which he specifically rapped over N*E*R*D instrumentals. Here Mickey Factz collaborated with Steve-O who pushed him to really begin to listen to N*E*R*D and served as creative inspiration. Factz then worked to chop up the beats and make the project unique, gaining the attention of Pharrell himself.
Flashback Vol.1: Back to the Future (2007), which was created in order to pay homage to the type of music that Factz grew up with. Mickey recorded about 40 tracks in total for this album and even after recording, he entered into another process that included the remix of over half the songs and instrumentals.
For 2008's The Leak, Vol.1: The Understanding, Factz leaked one song every week on MySpace for 17 weeks. One of the songs, "I'm Sean (50 Shots More)", was written from the perspective of Sean Bell, who was killed by New York police in 2006.
In a 2008 interview Factz recalled, "I had heard a few records from some New York artists, whose names I won't mention, and I wasn't very pleased with what they were doing. [...] I decided that I was going to get in the shoes of Sean Bell and talk about the night of him dying, him at his funeral, him seeing the press conferences and him just talking to the youth and letting them know that we have to come together and do better than what's going on right now." Factz's song-per-week release strategy was also used for The Leak, Vol.2: The Inspiration, which contains guest appearances by Drake, Travie McCoy, and Tanya Morgan. The music video for "Rockin' N Rollin'", featuring The Cool Kids and produced by Precize, was added to rotation at MTV. Factz was named to XXL magazine's "Freshmen Class of '09" issue in 2008.
Factz contributed a song, "Rocker", to the soundtrack of the Fight Night Round 4 video game, and he signed to Battery Records in May 2010. Mickey Factz recently finished touring with Big Sean and is working on his album The Achievement, which is set to be released in Winter 2013/2014 Mickey Factz became the new member of All City Chess Club when Lupe Fiasco said at a radio station "Mickey Factz is part of All City Chess Club." While in the studio recording for his debut album, Mickey tweeted that Lupe Fiasco are collaborating on a track. Also pictures of the two together have surfaced on the internet recently. "I'm Better Than You (2010) was Mickey's way of expressing his sense of confidence and recognition of the competitiveness of music. "Love.Lust.Lost" (2011) was an album based on one of Factz' past relationship and was his attempt to get the girl he loved back. Although in the end, she slipped away, this album represents Mickey Factz' growth not only as an artist but also as a person. Deeply personal and honest, this was enjoyed by a wide variety of people who could relate to his deep and heartfelt lyrics.
In 2012, Factz tried to release Mickey MauSe under his label, but they considered it to be too artistic and did not back it up. Factz went on to release this experimental project himself and in the album, Mickey Mause became his pseudo character, thrown into the 1980s as a graffiti writer who was later kicked out by his parents for being a troubled youth. This project represented what it truly meant to be an artist and lots of research was done in order to learn about Mickey Mouse and that era of time. Lyrically, this mixtape is known for being one of Factz' best and gained him the opportunity to become closer to Lupe Fiasco.
Factz has a long history as a competitor in the sport of battle rap dating back to the original battle leagues, and hosting battles at Ultimate Rap League events.
In 2017, Factz was involved in the battle rap league KOTD's Massacre event where he battled West Coast rapper Daylyt.
