Amanda Cerny was born on June 26, 1991, in Pittsburgh, Pennsylvania, and is of Czech descent. She attended Florida State University, where she studied business and international business before leaving to pursue a media career. Her public profile began in October 2011, when she was featured as Playboy’s Playmate of the Month, an appearance that put her in front of a national audience before she had built any following of her own online, according to Wikipedia.

Cerny opened her YouTube channel on October 9, 2011, and soon after began posting six second comedy clips to Vine, the short form video app that would come to define her early career. She built her Vine following past 4.6 million by shooting relatable, punchline driven sketches and by collaborating with other rising Vine comedians such as Andrew Bachelor, known as King Bach, and Logan Paul, collaborations that cross pollinated audiences across the platform’s biggest accounts, per Wikipedia.

When Vine shut down in 2017, many of its biggest stars struggled to carry their audiences to another platform, but Cerny successfully rebuilt her career around Instagram and YouTube. She leaned into longer form comedy, travel vlogging, and lifestyle content, and by the time she spoke to Forbes in January 2018 she was already being described as one of the platform migration’s clearer success stories, having converted Vine fame into a durable, multi platform business rather than a fading internet moment, according to Forbes.

In August 2017, LiveXLive Media named Cerny the head of its newly launched digital talent division, LiveXLive Influencers, tasking her with recruiting and managing creators across art, music, fashion, sports, and cooking, with a particular focus on women creators, and she made her directorial debut helming the music video for the division’s first collaborative single, “Come Thru,” as reported by Variety. Her acting credits grew alongside her online career, including Internet Famous in 2016, 211 in 2018, an uncredited role in Creed II in 2018, Rim of the World in 2019, and The Babysitter: Killer Queen in 2020, along with a guest appearance on the 2021 iCarly reboot, per her IMDb profile.

Cerny has built one of the larger combined social followings to emerge from the Vine generation, with her Instagram account alone tracked at more than 20 million followers by analytics platforms and her YouTube channel surpassing 2.5 million subscribers and 240 million total views, according to HypeAuditor and the Wikipedia figures cited above. That combined reach across Instagram, YouTube, and other platforms is what publications and brand partners point to when describing her as one of the more commercially significant creators of her cohort, a status the Forbes profile framed around audience engagement rather than raw follower counts alone.

Cerny has worked with major consumer brands including Guess, Tinder, and Paramount Pictures, partnerships that Forbes described as central to the multimillion dollar business she built once she moved beyond Vine, per the Forbes profile. As a longtime vegan, she has also partnered with PETA on advocacy campaigns, including a comedic video demonstrating alternative, meat-free household uses for animal products, a partnership that doubled as both activism and sponsored content for the organization, as covered by PETA.

In July 2018, Cerny co-founded the subscription streaming service Zeus Network alongside fellow creators King Bach and DeStorm Power and television producer Lemuel Plummer, who serves as the company’s president and chief executive; the platform was built around original scripted and unscripted shows starring internet-first talent, as detailed by Variety and the Zeus Network Wikipedia entry. She has also built a fitness business under the CERNY FIT name, offering at-home training programs through the Fitplan app that give subscribers access to her own workout methods, according to the Fitplan listing for the program.

In 2019, Cerny purchased a newly built home in the Valley Village neighborhood of Los Angeles for 2.36 million dollars. The four bedroom, five bathroom property spans more than 3,700 square feet and includes a sculptural floating staircase, an eat-in kitchen with Italian tile and Miele appliances, two fireplaces, a backyard pool and spa, and smartphone controlled lighting, climate, and security systems, according to Urban Splatter.
