[2] In her early youth, she planned to become a teacher or lawyer or journalist, thinking a career in music would be too uncertain.

[6] After finishing high school in Ålesund, Sigrid moved to Bergen for its indie music scene, living in a shared flat with her brother and friends.

[6][3] She began studying comparative politics at university, but soon dropped out to pursue her music career.

[9] In 2016, in partnership with Martin Sjølie, she wrote "Don't Kill My Vibe", inspired by an incident where a producer belittled and patronized her in a songwriting session.

She was also a part of The Sims 4: Parenthood soundtrack with the Simlish version of her song, "Don't Kill My Vibe".

[27] In 2020, Sigrid was one of many artists that took part in a BBC Radio 1 Live Lounge cover of the Foo Fighters song "Times Like These" that was organised to raise funds for the COVID-19 pandemic.

Sigrid's songs are underpinned by anger, melancholia, and disappointment; she says that it is easier to write about frustration than about having a nice time.

[2] For her love songs Sigrid cites Bonnie Raitt, Coldplay, Adele, Lykke Li, and Robyn as influences.
