Gençay Aytekin was born in Istanbul in 1984. Between 2005-2011, he studied at Mimar Sinan Fine Arts University Painting Department under the guidance of Prof. Aydın Ayan. 

In 2011, he held his first solo exhibition at Sanatorium. Between 2012 and 2022, he worked as an assistant in the studio of the well-known Turkish artist Ekrem Yalçındağ. He also assisted Hermann Nitsch during his performances in Istanbul in 2013. 

Aytekin's childhood interest in cartoons has formed the basis of his current artistic practice, which is characterized by distinctive colors and dynamic lines. As one of the representatives of the new generation of pop art, Aytekin explores the challenges of existence and adulthood with a childish naivety. Inspired by pop art and the colorful world of the popular culture of his upbringing, he aims to create a vibrant and playful world. 

In addition to institutional collections such as Özyeğin University, the artist's works are also included in various private collections.
