Finneas Baird O’Connell (born July 30, 1997) is an American singer-songwriter, record producer, multi-instrumentalist, composer, and actor who has built one of the most quietly dominant résumés in modern pop music. Known mononymously as FINNEAS, he operates in a rare space: the architect behind some of the decade’s biggest records who also steps out front as a solo artist with his own distinct creative identity, warmer, more earnest, and less genre-destabilizing than the work he crafts for his younger sister, Billie Eilish.
His fingerprints are on every note of Eilish’s catalog, from the bedroom-produced debut that swept the Big Four at the 2020 Grammys through Hit Me Hard and Soft in 2024. But reducing him to a behind-the-scenes figure misses the picture. He has won 11 Grammy Awards, two Academy Awards, and two Golden Globes, produced chart-toppers for Selena Gomez, co-written a James Bond theme, scored an Alfonso Cuarón television series, designed a signature Fender guitar, and released two studio albums of his own. All before turning 29.
What makes FINNEAS distinctive isn’t just range, it’s an almost compulsive need to learn the next thing. He moved from bedroom pop production to stadium-scale tours to orchestral film scoring to acting roles, each step driven by the same impulse he described to Gold Derby in 2024: the feeling of not knowing how to do something is precisely what pushes him to figure it out. That restlessness, more than any single hit, is the engine of his career.

Early Life & Education
Finneas O’Connell was born and raised in Los Angeles, the first child of actress and screenwriter Maggie Baird and actor Patrick O’Connell. Both parents were working musicians as well as performers, and the household ran on creativity. Finneas and his younger sister, Billie Eilish, were homeschooled, a decision their parents made specifically to give both kids room to explore creative interests without the constraints of a conventional school schedule. The approach paid off in ways no one could have predicted.
Music clicked early. At 11, Finneas went to a Green Day concert and came home gripping bass picks he had caught from the stage, a moment he later described as a turning point. By 12, he had taken a songwriting class with his mother and started teaching himself Logic Pro in his bedroom. He joined the Los Angeles Children’s Chorus, formed a pop-punk band called The Slightlys that was good enough to land a Warped Tour slot, and began writing songs at a pace that outstripped anything his peers were doing. He was simultaneously building an acting career, appearing in Bad Teacher at 14, co-starring alongside his mother in the indie film Life Inside Out, and landing recurring roles on Modern Family and the final season of Glee.
The pivot from screen to studio came in 2015, when he wrote a song called “Ocean Eyes” for The Slightlys and decided at the last minute that it would sound better sung by his 13-year-old sister. They uploaded it to SoundCloud. It went viral. Everything after that flowed from a bedroom in Highland Park.
Career Highlights and Milestones
The viral explosion of “Ocean Eyes” turned Billie Eilish into a phenomenon, and it cemented Finneas as her core creative partner, a role he has never relinquished. He co-wrote and produced Eilish’s debut EP Don’t Smile at Me (2017) and her first studio album When We All Fall Asleep, Where Do We Go? (2019), both made almost entirely in his childhood bedroom. The debut album debuted at number one in the U.S. and U.K., and at the 2020 Grammys, the siblings swept the Big Four categories, Record of the Year, Song of the Year, Album of the Year, and Best New Artist, with Finneas also winning Producer of the Year, Non-Classical. He was the youngest person ever to take that prize.
From there, the scope expanded. He produced Selena Gomez’s number-one single “Lose You to Love Me” (2019), co-wrote tracks for Camila Cabello, Demi Lovato, Justin Bieber, and Tate McRae, and collaborated with artists as varied as Kid Cudi, Rosalía, and Ringo Starr. With Eilish, he wrote the Bond theme “No Time to Die” (2021), which won an Academy Award and a Golden Globe, then followed it with “What Was I Made For?” from Barbie (2023), which won the same pair of awards, making them the youngest two-time Oscar winners in music history. At the 2026 Grammys, they won their record-setting third Song of the Year for “Wildflower,” a total no other songwriting team in Grammy history has reached.
His solo career runs on a separate but parallel track. The Blood Harmony EP (2019) established his voice, more romantic, sunlit, and emotionally direct than the music he builds for Eilish. His debut album Optimist (2021) expanded on that, and his second album For Cryin’ Out Loud! (2024) was his most collaborative effort yet, made with a full band in the studio rather than alone in a room. He toured in support of it across four continents in early 2025, his largest headlining run to date.
Beyond music, Finneas has built a second career as a composer. He scored the teen drama The Fallout (2021) and B.J. Novak’s Vengeance (2022), wrote music for Pixar’s fictional boyband 4*Town in Turning Red (2022), and in 2024 composed the full orchestral score for Alfonso Cuarón’s Apple TV+ series Disclaimer, a Bach-inspired chamber work that was a deliberate departure from anything he had done before. He also returned to acting, guest-starring as Jason in the Peacock comedy Laid (2024). In 2024, Fender partnered with him to release two signature Acoustasonic Telecaster models, the first artist Acoustasonic guitars the company has ever produced.
