He is best known for his songwriting work for Canadian singer Justin Bieber, having been credited on each of his albums since his compilation, Journals (2013). Boyd has written four Billboard Hot 100-number one singles with Bieber's performances on "Despacito (Remix)" and "I'm the One", and his singles "Where Are Ü Now" and "What Do You Mean?". Furthermore, Boyd has written Bieber's top 40 singles "Intentions", "Forever", "I Don't Care", and "All That Matters". Prior, Boyd was credited on albums for R&B group 112, and co-wrote Usher's 2004 single "Caught Up", which peaked within the chart's top ten. He often writes for Scott Storch productions and co-writes in tandem with Sasha Sirota.^[5]

As a recording artist, Boyd signed with Capitol Records to release his debut studio album, Poo Bear Presents Bearthday Music (2018).^[6] He launched the distribution platform, Fwaygo in 2023.^[7]

Boyd was born in New Haven, Connecticut. He moved with his mother to Atlanta, Georgia, at age 9 after a tornado left them homeless.^[8] His first career breakthrough came from working with R&B group 112, for whom he co-wrote the songs "Dance with Me" and "Peaches & Cream".^[9]

Following his early success with 112, Boyd continued to write with other artists, including Chris Brown, Jill Scott, and Mariah Carey.^[10] In 2004, Usher's album Confessions was released and contained the single "Caught Up", which Boyd co-wrote with Ryan Toby and producers Dre & Vidal. The album was certified diamond by the Recording Industry Association of America (RIAA), selling over 10 million copies in the US,^[11] and is largely considered as one of the best albums of the decade.^[12][13][14] "Caught Up" was the fifth single released from the album, peaking at number 8 on the Billboard Hot 100.

While in Las Vegas, Nevada, in January 2013, Boyd was introduced to Justin Bieber through rapper Lil Twist and other friends of Bieber's. The two bonded over similar upbringings and tastes in music and traveled the world together while working on music for Bieber's album. During this time, Boyd eschewed working with other artists, devoting his time exclusively to Bieber.^[8] He co-wrote the majority of the songs on Bieber's albums Journals and Purpose, including "No Pressure", where he is also credited as producer, "PYD", "All That Matters", and the double-platinum selling singles "Where Are Ü Now", which peaked at number 8 on the Billboard Hot 100, and "What Do You Mean?", which peaked at number 1 on the Hot 100. On April 27, 2018, Boyd released his debut studio album Poo Bear Presents Bearthday Music, via Capitol Records.

In the latter part of the 2010s, Boyd's work found success in both the Latin and country music genres. "Despacito (Remix)" was named the number 1 Latin song in the history of the Billboard charts,^[15] and Dan + Shay's hit "10,000 Hours" reached number 1 on the Billboard Hot Country Songs chart.

In addition, Boyd produced the songs "Mañana es Too Late" and "Lo Nuestro es Más", by Mexican pop duo Jesse & Joy, with the first one being a collaboration with Colombian reggaeton singer J Balvin.
