Digital media brand The Debrief has announced it is facing closure.
In a statement, the website said it could not "see a viable future", despite its recent success at the British Media Awards.
Launched in 2014, The Debrief aimed to reflect the contemporary issues facing young women.
The statement added many of its writers would now likely contribute to sister publication, Grazia.
"The Debrief was borne from the realisation that there was nowhere online that was talking to young women about the topics they cared about the most in a way they could relate to," it said.
Speaking to The Guardian when the website launched, its co-founder Lauren Holleyoake defined The Debrief's demographic as "constantly connected, influential, 20-something women".
During its four-year run, the website has conducted numerous investigations, including Mad About The Pill - launched in conjunction with BBC Women's Hour - which explored the link between hormone contraceptives and mental health.
It also helped to enforce a ban on letting agency fees through its Make Renting Fair campaign.
The recipient of numerous awards, the website came third in the digital product of the year category at last year's British Media Awards.
Reacting on social media, many readers said they were "heartbroken" at the closure.
The Debrief, which did some really good stuff, is being closed by Bauer (who also own Grazia/Closer) because they "cannot see a viable future for this brand". Was originally launched in 2014 as their big punt to win younger online audience. https://t.co/00iTfUnyBx— Jim Waterson (@jimwaterson) April 24, 2018
I wrote for the Debrief when it first launched and I'm gutted by this news. It gave so many young women their first break in media and was full of talented journalists doing great work https://t.co/Ni826ujZLp— Zing Tsjeng (@misszing) April 24, 2018
Sad to hear that The Debrief is closing. Their #MadAboutThePill investigation into the mental health effects of the pill raised awareness of an issue I and many other women care deeply about - and it was one of many awesome and important campaigns. https://t.co/XtjHXEsVML— Jess Denham (@jess_denham) April 24, 2018
