Agboh (then Kemp) grew up in Westport, Connecticut, and began reading college textbooks at the age of eight. In 1994, she graduated from Staples High School and went on to receive her bachelor's degree from Brown University as well as her Master's in English Literature from Columbia University.
At the age of 26, Agboh left Westport and went to Los Angeles, California, to further pursue her dream as a television writer. There she garnered her big break by becoming a staff writer for the then-Fox hit series The Bernie Mac Show. She then began writing for other television shows such as Eli Stone, Justice and Beauty and the Beast (a 2012 remake of the 1987 series of the same name) before eventually becoming increasingly known for her writing of episodes for the CBS political drama series The Good Wife.
Her idea for what would become the first series she ever sold and pitched, Power came about when she met rapper 50 Cent and executive producer Mark Canton at a coffeehouse in Los Angeles where she thought up the concept about a guy who becomes destined to leave his life as a drug dealer behind him to become a successful club owner and businessman. She soon penned the script to Power with Canton and 50 alongside her, both serving as executive producers and the show was green lit by Starz on June 17, 2013, with an ordered eight-episode first season set to air the following year.
