who i am

Ethan Hae-Sung Kim. Korean American, born and raised in LA. I went to UC Berkeley for EECS and dropped out to build. Right now I'm living in Seoul and making content full time, and I co-founded Orbit, where we build custom AI solutions for businesses looking to scale.

Off the clock: I love songwriting — been at it as long as I've been able to write — and lifting.

personal brand

Sincerely Haesung

My personal brand on Instagram, TikTok, YouTube and Twitch: 32K followers, 31M+ views, and brand collaborations I film and edit myself. Content creation has been the goal since I was a kid, and now it's what I do full time.

the soundtrack

I've been songwriting for as long as I've been able to write. As a kid I'd copy down every lyric of a song by hand, so I could keep singing in my room when I wasn't allowed my tech.

I started producing in rap, went underground — plugg, pluggnb — then admitted I wasn't making the music I actually wanted to make. Now it's whatever the song needs; lately, indie rock.

most of it is unreleased — i'm not pursuing music as a career just yet, but it's my biggest passion.
