Singampuli was born and brought up in Theni, Periyakulam and after studying engineering in Bangalore, he arrived in Chennai looking for a career in films. During his stint as an assistant director with Sundar C, Singampuli suggested the original plot point of Unnaithedi to the director and Sundar wrote the script of the film within a week, before discussing the line with actor Ajith Kumar. Ajith was initially unimpressed but agreed to do the romantic story anyway, mentioning that if the film became a success he would feature in a future film to be directed by Singampuli.
