Claßen began making her videos in December 2012, gaining her first 500 subscribers within less than two months.[4] Her videos focus on hair, makeup, fashion, travel, lifestyle and challenges.[1]

In 2014, she won an award in the Beauty, Fashion, and Lifestyle category at the Google Play Awards.[6] As of 2017, she had the fourth most popular YouTube channel in Germany.[7]

In May 2015, she launched her own cosmetics brand called Bilou,[8] meant as an acronym for "Bibi loves you".

Over time, the variety of her cosmetics products, namely the flavours of her shampoos, has increased.

In October 2015, in cooperation with the German Telekom and Sony Mobile, a customized variant of the Sony Xperia M4 Aqua mobile phone was released in Germany, known as the Bibi-Phone edition. It differentiates from the original with a picture of Bianca's face and her signature printed on the unit's rear cover, and additional wallpaper pictures and ring tones.[9]

In March 2016, her channel surpassed three million subscribers.[10]

Bianca Claßen among her spouse Julian Claßen appeared in YouTube Rewind 2015[11] and 2016.[12]

As the year commenced, her channel surpassing Erik Range's channel Gronkh and claiming the spot as the most-subscribed German-language YouTube channel approached within an increasingly foreseeable time.[13] A campaign attempting to sustain the latter's spot gained traction on social media under the hash tag #AbonniertGronkhDeabonniertBibi ("subscribe to Gronkh, unsubscribe from Bibi"), slightly delaying the surpassion.[14][15]

In May 2017, Bianca Claßen released her first song under the nickname Bibi H., titled "How It Is (Wap Bap …)". Within several days of its release, the song's video became the eleventh most disliked video on YouTube, and most disliked video on any German YouTube channel,[16] surpassing the multiple formerly most downvoted videos by "ApoRed" within hours.

In November 2017, on the second operational day of her iPhone X smartphone, she noticed a defective pixel on its display panel. She attempted to create a screen capture of that hardware defect, sharing it on Twitter. The incident went viral with responses educating her how a software-based screen capture is unable to capture hardware-based panel defects.[17][18][19]

In January 2019, the couple reacted to videos of low view counts, including a reupload of a lost 2015 telephony commercial involving her, posted hours prior to the recording, and a man parodizing their pregnancy photos.[20]

In March 2020, the couple discussed their struggle of finding a hospital to birth their daughter under the Coronavirus pandemic.[21]

In January 2021, the couple found a molded mobile phone case in a wardrobe, and jokingly decided to sell it on eBay as an artistic obstacle. The auction went viral due to her promotion of it on her Instagram Stories channel, clocking in €133.000 as the highest bid. The auction was cancelled, however.[22][23]

She is married to the German YouTuber Julian Claßen, nicknamed "Julienco".[24]

After a nine-year relationship starting on 1 March 2009, they married on 12 September 2018.[25]

Their relationship is often dubbed using the community-created portmanteau "Julianca", a mixture of both their first names.

On 12 May 2018, she announced her pregnancy through a cinematic, professionally produced three-minute film that has amassed 7.67 Million views as of 11 October 2019.[26] that was teased twice days in advance.[27][28]

She gave birth to her son on 4 October 2018, named Lio. She later announced that she was pregnant with their second child, a girl. On 20 March 2020 she gave birth to her daughter Emily.
