Khushbu made her debut as a film producer through the action drama film Giri (2004) directed by her husband Sundar C and featuring Arjun, Reemma Sen and Divya Spandana in the lead roles. The film performed well at the box office, prompting her to carry on as a producer and she next made Rendu, a comedy drama featuring Madhavan in the lead role.
In 2016, a partner group from the parent Avni Groups company called Avni Movies produced the film, Hello Naan Pei Pesuren, with Sundar C being given production credits. The film was however also promoted through Avni Cinemax's official online pages. The same procedure was then followed for Meesaiya Murukku (2017).
