300 Publishing Inks Songwriter-Producer Sean Momberger.

300 Publishing – the publishing arm of 300 Entertainment – today announced the signing of fast-rising, songwriter-producer Sean Momberger [Jack Harlow, Doja Cat, Justin Bieber, Chris Brown], who joins a growing roster including 1st Class [Anycia, BabyDrill, Karrahbooo, DaBaby], and Jumbo Sounds [2Rare, Philly Goats, Lay Bankz, D STURDY] in addition to artists such as Hunxho and Young Thug.

300 Elektra Entertainment Chairman & CEO Kevin Liles said, “My co-Presidents Rayna, Selim and I are always looking for talent that takes chances, break boundaries, and fearlessly creates with integrity. Sean’s a perfect example of what 300 stands for and we’re excited to partner with him as he shows the world what he’s capable of.”

300 Publishing Vice President Jenn Essiembre said, “Sean has an incredible work ethic and brilliant ear, it’s no surprise that he’s become one of the most sought-after talents in the business right now. We’re invested in long-term development and success for our roster, and Sean is just getting started.”

Momberger said, “300 Entertainment has built such a deep culture and singular identity within the music industry. It’s truly an honor to be signed to 300 Publishing and join a roster of such talented creators.”

Momberger notably co-produced Jack Harlow’s “Lovin On Me,” which just vaulted to No. 1 on the Billboard Hot 100 this week. This achievement stands out as 300 Publishing’s “first No. 1 on the Billboard Hot 100 and No. 1 UK Single via a non-performing creative.” Plus, it marks the company’s third Hot 100 No. 1 overall following Young Thug hits “Havana” with Camila Cabello and “Way 2 Sexy” with Drake & Future.

In 2023, 300 Publishing signees have co-written and/or co-produced music for Morgan Wallen, Metro Boomin, Travis Scott, Megan Thee Stallion, Babyface, Quavo, Offset, Don Toliver, Rae Sremmurd, Saweetie, JELEEL!, Ciara, YG & Tyga, Rick Ross & Meek Mill, and more.
