Question: Who founded the record company that Hopsin was signed to in 2007?

<P0-S0> Motown is an American record company. <P0-S1>  The record company was founded by Berry Gordy Jr. as Tamla Records on January 12, 1959, and was incorporated as Motown Record Corporation on April 14, 1960, in Detroit, Michigan. <P0-S2>  The name, a portmanteau of "motor" and "town", has also become a nickname for Detroit. <P0-S3>  Motown played an important role in the racial integration of popular music as an African American-owned record label that achieved significant crossover success. <P0-S4>  In the 1960s, Motown and its subsidiary labels (including Tamla Motown, the brand used outside the US) were the most successful proponents of what came to be known as the Motown Sound, a style of soul music with a distinct pop influence. <P0-S5>  During the 1960s, Motown achieved spectacular success for a small record company: 79 records in the Top Ten of the "Billboard" Hot 100 record chart between 1960 and 1969. <SEP> <P1-S0> Cora E. (born 1968 in Kiel, Germany as Sylvia Macco) is a former nurse turned hip-hop artist who emerged in the early underground German hip hop culture. <P1-S1>  At the time that she came to prominence, she was not only one of the originators, but she was also one of the few females in the industry. <P1-S2>  She was one of the very few old-school acts to be taken on by a major record label after she released two singles with Buback record company. <P1-S3>  She wrote her own lyrics, and worked independently. <P1-S4>  Many pegged her as a rapper but she called herself a "hip hopper." <P1-S5>  Despite this, she and another traditionalist group Advanced Chemistry insisted that rap and hip-hop are inseparable. <P1-S6>  The social criticisms based on personal experience in her music link her to other Hip-Hop artists in Germany, such as Advanced Chemistry. <P1-S7>  Her old school sound interested EMI; they signed her and another female artist, Tic Tac Toe. <P1-S8>  She had success with the record company and her first single "Schlüsselkind" (Latchkey Kid) was a hit. <SEP> <P2-S0> Ruthless Records is an American record label, founded by Eazy-E and Dr.Dre. <P2-S1>  The record label was founded in Compton, California in 1986. <P2-S2>  The label's acts over the years have earned RIAA certifications of Platinum or higher on 15 of its released albums, including releases by N.W.A, Eazy-E, MC Ren, The D.O.C., Michel'le, J.J.Fad and Bone-Thugs-n-Harmony. <SEP> <P3-S0> Marcus Jamal Hopson (born July 18, 1985), better known by his stage name Hopsin, is an American rapper, record producer, director and actor from Los Angeles, California. <P3-S1>  In 2007, he was signed to Ruthless Records, and had founded his own record label, Funk Volume, in 2009. <P3-S2>  He would then go on to found another record label, Undercover Prodigy, in 2016. <P3-S3>  Hopsin has released four studio albums, "Gazing at the Moonlight" through Ruthless Records, "Raw", "Knock Madness" and "Pound Syndrome" along with the collaborative project Haywire (with SwizZz) through Funk Volume. <P3-S4>  He is well known for his use of white colored eye contacts in music videos, performances, and interviews.
