Songwriting and producing

Finneas is most famously known for his collaboration and work with his little sister Billie Eilish Pirate Baird O'Connell, he has said his experience playing characters helped in writing music for his sister Billie Eilish, as he writes from her perspective and for her vocal range. He stated: “Being able to hear an artist and emulate them has been a huge part of being successful as a producer and co-writer". When he writes for his sister, he wants to "write a song that I think she’ll relate to and enjoy singing and empathise with the lyrics and make her own", and when he writes with her he tries to "help her tell whatever story she’s trying to tell, bounce ideas off of her, listen to her ideas."
Finneas had written and produced the song "Ocean Eyes" originally for his band, and gave it to Eilish when her dance teacher asked them to write a song for a choreography. They posted the song on SoundCloud, garnering praise from various websites. Finneas's manager reached out to him in November 2015 to talk about Eilish's potential. Finneas then helped Eilish sign to the A&R company Platoon. He co-wrote and produced Eilish's debut EP Don't Smile at Me, which peaked at number 14 on the US Billboard 200. Finneas also co-wrote and produced Eilish's debut studio album, When We All Fall Asleep, Where Do We Go?, which debuted atop the US and UK charts. He won the 2020 Grammy Awards for Producer of the Year, Non-Classical; Record of the Year and Song of the Year for Eilish's "Bad Guy"; and Album of the Year and Best Engineered Album, Non-Classical for When We All Fall Asleep, Where Do We Go?
