[1][2] Kibinge has been described as a trailblazer for other female Kenyan filmmakers by scholar Clara Giruzzi, to which she has stated that she is just one of the many women who are at the forefront of the rebirth of film in Kenya.

In 1999 she left the advertising industry to pursue a filmmaking career and began directing commercial documentaries about Monsanto.

This movie does not only focus on the character's mental states but also helps the world to realize the collapsed situation of Kenya, which started from colonization.

Her movies can be about personal issues between a couple which audiences can easily relate to,[9] and also they can be about social problems occurring in Africa such as colonialism, war, and hunger.

As being known for documentary movies, her film style usually contains many establishing shots, which depict the entire city and people who live there, rather than keep focusing on one person's life.

[10] Kibinge began her career at McCann Erickson Kenya for eight years, where she was responsible for numerous award-winning adverts.

She has written and directed a short film for MNET, and she also produced corporate documentaries for IPPF, Monsanto, and Technoserve.

[4] In 2017, Kibinge was chosen to be an Oscar judge by the Academy of Motion Picture Arts and Sciences for the categories of documentary, international features and animation.

[12] Kibinge made her directorial debut when a producer who has worked in Hollywood, Njeri Karago asked her to direct a film titled Dangerous Affair.
