Floor Jansen performed as a guest vocalist with the Marine Band Of The Royal Netherlands Navy at the opening concert of Sail Harlingen in the Vluchthaven of Harlingen, Netherlands on July 2, 2026. Among the tracks she sang was a symphonic cover version of the METALLICA classic power ballad "Nothing Else Matters". The performance is now available for viewing.

Jansen released the official lyric video for her solo single "Run" in June 2026 via Revamp Music in collaboration with Warner Music. The track serves as the first single from her debut solo album "Paragon", which was released in March 2023. The album features a diverse range of pop-infused tracks and emotional ballads reflecting her musical evolution.

"Run" was produced by Gordon Groothedde, with whom Jansen previously collaborated on the final album of her former band AFTER FOREVER. Lyrically, the song explores themes of liberation, self-empowerment, and the courage to break free from societal expectations. The single marks a shift toward a darker, more intense sound in her solo work.

Jansen has maintained a strong international presence, with over 600,000 Instagram followers, more than 56,000 Bandsintown followers, and nearly one million monthly Spotify listeners. She has performed at major festivals including Wacken Open Air, Masters Of Rock, M'era Luna, and Sweden Rock Festival in 2024. In November 2022, she confirmed being cancer free after breast cancer surgery. In October 2023, she welcomed her second child, a daughter named Lucy, with SABATON drummer Hannes Van Dahl. The couple previously had a daughter named Freja, born in March 2017.
