Genius is an American digital media company founded on August 27, 2009, by Tom Lehman, Ilan Zechory, and Mahbod Moghadam. Its website serves as an online music encyclopedia allowing users to provide annotations and interpretation to song lyrics, news stories, sources, poetry, and documents. Originally launched as Rap Genius, with a focus on hip-hop music, the company attracted the attention and support of celebrities, and venture capital enabling further growth. The site expanded in 2014 to cover other forms of media, such as pop, literature, R&B, and added an annotation-embedded platform. That same year, an iPhone app was released. To reflect these new goals, the site relaunched as Genius in July 2014. An Android version was released in August 2015, and in 2016 and 2017, the company began producing music-focused original video content and hosting live events and concerts. Genius first started as a crowdsourced hip-hop focused site, and was originally named Rap Exegesis. The site changed its name to Rap Genius in December 2009 because "exegesis" was difficult for users to spell. It was created in August 2009 by founders Tom Lehman (who "entered the first line of code" for the website at 12:30 PM on August 19, 2009), Ilan Zechory, and Mahbod Moghadam, the three of whom met during their undergraduate years at Yale University. Lehman and Moghadam came up with the idea for the site in the summer of 2009 when Lehman asked Moghadam about the meaning of a Cam'ron lyric. After Lehman built the earliest version of the site, he—along with cofounders Moghadam and Zechory—decided to leave their jobs at D.E. Shaw and Google to pursue the idea full-time and bring it to fruition. In 2011, with the site "drawing over 1 million unique visitors per month", Rap Genius applied to start-up incubator Y Combinator, and "became the fastest-growing start-up in Y Combinator history", obtaining $1.8 million in seed funding, which enabled the founders to occupy offices in Williamsburg, Brooklyn.
