Kavya stepped into the music scene in 2014 with Ranjan Pramod`s romantic musical Rose Guitarinaal. The film`s music composer Shahbaz Aman, who was in search of a new voice, liked hers and offered her the song Engum Nalla Pookkal, which became her first breakthrough. It was followed by a string of songs tuned by Shaan Rahman for the films Praise the Lord, Oru Vadakkan Selfie and Nam Duniya Nam Style, which was her Kannada debut. She was next heard in Lavender, composed by Deepak Dev, where she performed two tracks for the film. The soundtrack was lauded for Dev`s combination of Western music and old-world lyrics.

She debuted in the Tamil film music industry through the song Hey Umayaal for the film Urumeen, scored by Achu Rajamani.

Her first taste of success came after singing Neeyen Kaataai from the film Jo and the Boy, composed by Rahul Subrahmanian. She received wider recognition following the release of the breezy melody Ee Shishirakalam, tuned by Shaan Rahman for the film Jacobinte Swargarajyam. The song was an instant hit and was praised by critics and audiences alike. In 2016, she made her Telugu debut through the song Jakkanna from the eponymous film. The track was lauded for its grooviness.
