41. Tom Lehman and Ilan Zechory

Cofounders, Genius

The website formerly known as Rap Genius has had a turbulent year. Tom Lehman and Ilan Zechory fired cofounder Mahbod Moghadam after he annotated the UCSB shooter’s memoir with bizarre and inappropriate comments.

But there appears to be no bad blood between the three cofounders, and Rap Genius has recently rebranded as Genius, which is for “the crowdsourced annotation of music, news, literature, history, and just about any other text you could imagine,” according to its site.

In February, Cavaliers owner Dan Gilbert offered to lead a $40 million investment in the company, valuing Genius at several hundred million dollars.
