Mini bio

How it started.

Ironmouse began streaming in 2017 to find company while living with common variable immunodeficiency, or CVID. Using a virtual avatar let her connect with people while keeping her face private. She had hoped to become an opera singer, and music became part of her life online.

Finding her audience.

Her 2022 subathon helped bring her to a much wider audience. In 2023, she won Content Creator of the Year at The Game Awards. She also briefly held Twitch’s subscription record in September 2024.

Music and community.

Her work now spans original music, collaborations and Club Ironmouse concerts. She became independent in July 2025 after leaving VShojo. Fundraising for the Immune Deficiency Foundation remains a recurring part of her work, including projects with her friend and fellow streamer CDawgVA.
