He named Jon Bellion, Justin Bieber, and The Beatles among his musical inspirations.
Alongside performing, Herron co-wrote some of Why Don’t We’s top songs, including “8 Letters” and “Fallin’ (Adrenaline).”

Zach Herron Career
Zach Herron built his career in stages, starting with social media covers, moving into solo singles, then joining one of the biggest pop boy bands of the late 2010s, and now stepping forward as a solo artist.
Early Solo Career (2016)
Herron began posting singing videos on Instagram and YouTube as a teenager. His covers attracted attention for his clear, controlled voice and natural stage presence.
The breakthrough came in January 2016. A classmate at school asked him to sing, and he performed “Stitches” by Shawn Mendes.
Students in the class recorded the performance, and it spread across social media rapidly, crossing 10 million views within seven days.
That wave of attention helped him land live gigs and tour dates. In January 2016, he released his debut solo single, “Timelapse.” His second solo single, “Why,” followed in June of that same year.
Why Don’t We (2016-2022)
In September 2016, Herron joined the five-piece group Why Don’t We, alongside Daniel Seavey, Jonah Marais, Jack Avery, and Corbyn Besson.
The members had all met through social media tours like DigiTour, and they formed the group officially on September 27, 2016.
Their debut single, “Taking You,” came out in October 2016, followed by their first EP, Only the Beginning, in November 2016.
They released four more EPs over the next year, building a strong fanbase before signing with Atlantic Records in 2017.
Why Don’t We released their first full studio album, 8 Letters, on August 31, 2018. The album peaked at number nine on the Billboard 200.
Singles from the album included “Hooked,” “Talk,” and the title track “8 Letters.” The band headlined the 8 Letters Tour in 2019, playing venues across North America.
Their second and final studio album, The Good Times and the Bad Ones, came out on January 15, 2021. It debuted at number three on the Billboard 200, making it the band’s highest chart entry.
The album was largely self-produced, with contributions from Travis Barker, Skrillex, and Timbaland.
The lead single, “Fallin’ (Adrenaline),” released in September 2020, gave the band their first ever Billboard Hot 100 entry.
In 2022, a legal dispute with former manager David Loeffler led to the band going on hiatus and cancelling their tour.
The members filed a counter-suit alleging abuse. The lawsuit concluded in early 2025, and Why Don’t We officially lost the rights to their group name in February 2025, marking the end of the band.
Solo Return (2024-Present)
After the band’s conclusion, Herron moved forward as a solo artist. He released “Caroline” on July 26, 2024, his first solo single since Why Don’t We’s hiatus.
The track, produced with Mitch Allen, racked up nearly 500,000 Spotify streams on release and showed a more mature pop-rock direction.
Herron also began streaming regularly on Twitch under the handle herronzach, connecting directly with his fanbase.
He posts music updates and interacts with fans live on the platform, with regular Tuesday and Thursday streams.
