Sabath took a leave of absence from high school in his senior year to write and record in Los Angeles. By then, he had a manager, Don Isaac, and an agent, who also represented Justin Bieber. In early 2017, he signed a publishing deal with Sony/ATV Publishing, and later that year attended a multi-day Sony/ATV publishing camp. While there, he wrote "Get Loud for Me" with the singer Grizzle. The song was used in an NFL/Bose commercial, and became a hit: it was streamed more than 4.4 million times, and added to 67,000 playlists. "Get Loud for Me" was later used in ads for Adidas and the Need for Speed Payback video game. He also co-wrote Daphne Willis' "Do It Like This", at the Sony/ATV camp; it was used in commercials for Comcast/Xfinity and became a "phenomenon" in South Korea.
