Rolf Jacob Sartorius (born October 2, 2002), better known as Jacob Sartorius (/dʒeɪkəb sərtɔɪriːʌs/), is an American singer and internet personality, who rose to fame via social media from posting lip-syncing videos on Musical.ly. In 2016, he released his debut single "Sweatshirt", which reached the Hot 100 charts in the United States and Canada. Several publications including Billboard and Business Insider have predicted Sartorius to become "the next Justin Bieber". In 2016, Google announced Jacob Sartorius was the 9th most searched musical artist of the year along with artists such as Beyoncé and Kanye West.
Sartorius was born in Oklahoma on October 2, 2002. Shortly after his birth, he was adopted and moved to Virginia because his birth parents were unable to take care of him. He was raised in Reston, Virginia by his adoptive parents. At age 7, Sartorius began acting in musicals, where he discovered his love for performing but caused people to bully him.
In 2014, Sartorius uploaded his first online video to Vine at 11 years old. The video, which was a message about anti-bullying, went viral and began his fame on social media. After regularly posting videos to Vine, Sartorius became mildly popular on the app. Later that year, Sartorius joined Musical.ly where his online fame took off. His lip-syncing videos on the app became very popular and led him to become one of the app's top stars with over 8 million followers.
Sartorius' newfound fame worsened the bullying at school. In 2016, Sartorius admitted he had to switch schools three different times in 2015 due to getting "verbally attacked, pushed, and teased" by classmates. Social media offered him an escape from bullying, with Sartorius stating: "Before Musical.ly, I wasn't the most outgoing. The app helped me goof off. It's like no one is watching besides the camera."
After rising to fame via social media, Sartorius signed to an independent record label and released his debut single "Sweatshirt" on May 3, 2016. The song peaked at No. 90 on the US Billboard Hot 100, No. 81 on the Canadian Hot 100 and No. 10 on iTunes. Sartorius performed the song for the first time in Baltimore on May 7 during the Magcon tour, a tour where fans can meet and interact with Internet personalities and see them perform.
After the tour, Sartorius released two more singles, "Hit or Miss" and "All My Friends". With "Hit or Miss" debuting at No. 72 in the United States, it is his highest charting single to date. On September 13, 2016, Sartorius announced the All My Friends Tour, a solo mini-tour where he performed in Philadelphia, Pittsburgh, Baltimore, San Diego, Anaheim, and Los Angeles.
