After completing Chemical Engineering, Karthik along with his friend Sunil Vishnu quit their respective jobs and started the event management company "Evam", which today is a theatre company of renown.
Karthik made his acting debut with Alaipayuthey (2000) portraying a small role as Shalini's prospective suitor. He was first test shot for the role of R. Madhavan in Alaipayuthey (2000) and rejected as he was too young; he was 22 years old at the time. He went on to portray supporting roles notably in films like Yaaradi Nee Mohini (2008) and Poi Solla Porom (2008).
In November 2016, Karthik expressed regret for getting typecast in particular roles, and wrote about his "retirement" from the film industry.
Karthik Kumar is also a prolific stand-up comedian who has done three stand-up specials. His first special, #PokeMe has more than half a million views on YouTube. His second special was titled "Second Decoction". And his third special Blood Chutney streams on Amazon Prime. He has performed over 1000 shows across India, USA, UK, Singapore, Malaysia and Hong Kong. He is managed by Evam Standup Tamasha, a leading stand-up movement in South India.
