Kim In Seong, known simply as In Seong, is a South Korean singer, dancer, musical actor, and member of SF9 (에스에프나인). He graduated from Gyeonggi High School, and he later obtained a bachelor's degree in Political Science and Economics from Kyung Hee University and a master's degree in Hotel and Tourism from Kyung Hee Cyber University.

Before debuting, FNC Entertainment (FNC엔터테인먼트) decided to test their trainees, and he performed in Japan in December 2015. Then, he was introduced as a member of NEOZ DANCE through the survival show "d.o.b. (dance or band)". They competed against the trainees in team NEOZ BAND (later rebranded as HONEYST) for the chance to debut as a group, eventually defeating them after the public voting. However, FNC announced that NEOZ DANCE will rebrand before their debut.

He made his debut in October 2016 as SF9's main vocalist with their first single album, "Feeling Sensation". In 2017, the group found their breakthrough when their first EP, "Burning Sensation", reached #6 on the Billboard World Albums Chart. They also debuted in Japan with a Japanese version of their debut lead single "Fanfare" and had successful concerts in Japan and in the United States. They have enjoyed continued success since then, releasing music and having events around the world.

In 2021, he renewed his contract with FNC Entertainment. He enlisted for his mandatory military service on March 21, 2022, and was discharged on September 20, 2023.
