Kumar, originally hailing from Tirumangalam, Madurai, first came to Chennai for his MSc Psychology classes that he was pursuing through distance education at Madras University in the early 2000s. During the period, he had also started going for classes at Arena Multimedia in Madurai before taking a transfer to Chennai. In August 2011, he started pre-production for Attakathi featuring an all new cast and directed by newcomer Ranjith, an assistant of director Venkat Prabhu. Kumar was insistent about meeting deadlines so the film began shooting on 26 September, finished shooting by 8 December and had the audio release on 9 January 2012. In 2014, Kumar produced three further films which won positive reviews and achieved box office success. Ramesh's murder-mystery film Thegidi starring Ashok Selvan and Janani Iyer, opened to critical acclaim with Baradwaj Rangan. The film was made at a cost of 2.4 crores and had recovered its cost through satellite rights alone, becoming one of the most successful films of the year, considering collection ratio on investment. His next, Ram's Mundaasupatti, was an adventure comedy film based on a short film, and was set in a fictional village called Mundasupatti of the 1980s, where people believe bad luck will befall them if they are photographed.
