Kishan worked as assistant director to
Gautham Vasudev Menon for a year, before starring in
Sneha Geetham (2010). Kishan made his acting debut with
Prasthanam in the same year. Director
Deva Katta referred Kishan to his friends
Raj Nidimoru and
Krishna D.K., which led to Kishan's casting in his first Hindi venture,
Shor in the City (2011).
Taran Adarsh felt he was "first-rate" and displayed vulnerability with natural ease. Kishan then appeared in
Yaaruda Mahesh (2013). The actor says that he has resolved not to venture into such genres any more despite it being the order of the day in Tamil cinema and even though he has been approached for a sequel to the film. Kishan's major breakthrough came with his another 2013 release
Venkatadri Express opposite
Rakul Preet Singh. The film was a commercial success. Jeevi from
Idlebrain.com noted, "Sundeep Kishan excels as a solo commercial hero with right amount of performance and also dances well in the introduction scene." He then appeared in
Gundello Godari, which earned him nomination for
Filmfare Award for Best Supporting Actor – Telugu. It was a box office success too. Following several poorly received films, Kishan's career marked a turning point in 2017. He first appeared in
Maanagaram opposite
Regina Cassandra, as the rugged young man. The film was a box office success. Anupama Subramanian of
Deccan Chronicle noted, "Sundeep with his new makeover of a rugged person is impressive. He is full of energy and sparkles in action sequences." Then in
Maayavan, he played a crime inspector opposite
Lavanya Tripathi. The film emerged a moderate success. Manoj Kumar R was appreciative of him for playing his character well. Kishan turned into producer too with
Ninu Veedani Needanu Nene (2019),
A1 Express (2021) which fared decently at the box office. He expanded to web with the series
The Family Man (2019) and his performance in the spy thriller was widely appreciated. Later, he starred in the Telugu action thriller
Michael (2023). Kishan had three film releases in 2024. He first appeared alongside
Dhanush as a tribal in
Captain Miller. The film received positive response and was a commercial success. In
Ooru Peru Bhairavakona, he appeared as a stunt body double caught in a mysterious situation. Sangeetha Devi Dundoo stated that he delivers a "convincing performance". Kishan then played an alcoholic who turns against his brother (played by Dhanush) in
Raayan. Janani K noted, "Sundeep Kishan gets a meatier role and lives upto his character." A box office success, it emerged as the
highest-grossing Tamil film of the year. In 2025, Kishan first appeared in
Mazaka, as
Rao Ramesh’s son. BH Harsh of
Cinema Express stated, "Sundeep Kishan struggles to match Ramesh's unhinged energy but shares an endearing chemistry with the actor, and the two salvage many mediocre scenes with their timing." It was a box office failure. == Other work ==
