About Highline Entertainment:

An informative thread with all the relevant informations I found

Highline Entertainment (하이라인엔터테인먼트) was founded in October 24, 2017 by Manager S. (Shim Seran) and Noh Seungjin.

The company's name was House of Music (하우스오브뮤직) previously, until November 26, 2018.

The ceo is Shim Seran, she used to be a marketing director in Starship Entertainment. She joined the previous company in May 2012 and worked with Monsta X for RUSH.

Highline - the subsidiary - gets investments from Starship - the main company - in exchange for paying back a fraction of their profit, like a fraction of what Starship makes goes to Kakao M.

This thread has short introductions to all Highline artists. https://twitter.com/starshipkr/status/1226004349282729985?s=19

There are DJ's, producers, indie soloists, rappers... But no idols so I wonder what they're going to do with Wonho.

Address: 서울 강남구 삼성로146길 4-5, 6층

It's the 6th floor of the current Starship building the previous address was Starhill building which could explain Wonho's recent sighting at a cafe

I didn't find official website or email, both are extremely important, especially the email, I hope we get it soon.

Their Instagram had an "email" option but they removed the address, leaving a "@ example. com" instead. It doesn't work, in case you're wondering.

I also didn't find any trademarks under Highline's name, none of their artists have their stage names trademarked.
