Harriette Pilbeam was born on 4 May 1993 in Brisbane, Queensland. She started singing as a child, later learning guitar and bass in her teen years, as well as piano and clarinet later on. She studied at Queensland University of Technology, graduating with a Bachelor in Creative Industries, majoring in entertainment before pursuing live music as a creative outlet. Pilbeam began her career as a bassist in the band Go Violets, releasing two EPs with the band prior to their disbanding in 2014. She was also a part of the band Babaganouj, alongside her fellow Go Violets bandmate Ruby McGregor and former Yves Klein Blue guitarist Charles Sale. The trio released several EPs and singles, as well as an album entitled Jumbo Pets, before splitting up in 2023.

Pilbeam made her solo debut under the name Hatchie, her family nickname, with the release of her debut single "Try" in May 2017. The single gained her significant attention in her native Australia. She then signed with Ivy League Records and released her second single "Sure" in November 2017. In January 2018, she also signed with Double Double Whammy and Heavenly Recordings. In February, "Sure" was remixed by Cocteau Twins' guitarist Robin Guthrie. She released two more singles, "Sugar & Spice" and "Sleep", before releasing her debut EP Sugar & Spice on 25 May. The EP consists of the four previously released singles as well as one additional track, titled "Bad Guy".

On 24 October 2018, Hatchie released a new single titled "Adored" for Adult Swim's singles series. On 26 February 2019, Hatchie announced her debut studio album, Keepsake, and released the lead single "Without a Blush". It was followed by two more singles, "Stay with Me" and "Obsessed", before the album was released on 21 June.

On 14 September 2021, after announcing that she had signed with the Secretly Canadian label, Hatchie released the single "This Enchanted". On 19 January 2022, Hatchie released another single "Quicksand" off her second album, Giving the World Away. It was released on 22 April 2022. On 9 March 2023, she announced the release of the album's deluxe edition which would be digitally available on 7 April 2023.

Stereogum described Hatchie's music as "a cosmic concoction of dream-pop and shoegaze." Her sound has been compared to various acts, some which she herself cites as influences, including Cocteau Twins, the Sundays, Mazzy Star, Natalie Imbruglia, and the Cranberries. She has also cited My Bloody Valentine, Kate Bush, Alvvays, Siouxsie Sioux, Kylie Minogue, Sky Ferreira, Wolf Alice, Chairlift, and Carly Rae Jepsen among her influences.

Hatchie married her longtime partner and musical collaborator Joe Agius (aka RINSE) on 24 November, 2021. The wedding ceremony was held at Graceland Wedding Chapel in Las Vegas, Nevada.
