Early Life & Education

Anastasia Karanikolaou was born on June 9, 1997, in Woodland Hills, a neighborhood in the San Fernando Valley region of Los Angeles, California. She was raised in a proud Greek-American household by her father, Periklis Nikolaos Karanikolaou, a successful financial broker with World Financial Group, and her mother, Nicolette Karanikolaou. She grew up alongside her older sister, Alexia Karanikolaou, who is also a model and digital creator.

Growing up in Southern California, Anastasia was immersed in creative and expressive environments from an early age. She developed an eye for fashion, makeup artistry, and photography during her early middle school years. Around the age of eleven, she crossed paths with Kylie Jenner at a Barnes & Noble bookstore event, forming an immediate bond that grew into a lifelong sisterly connection.

As her modeling opportunities and social media interest began expanding rapidly in her mid-teens, traditional school schedules became difficult to manage. Karanikolaou transitioned into home schooling to finish her secondary education, earning her high school diploma while gaining the flexibility to attend photo shoots, manage casting calls, and create online content full-time.

Career Journey & Recent Activity in 2026

While many in the public eye began their careers purely on television, Karanikolaou was one of the early pioneers of creator-led monetization in the mid-2010s. She transformed an initial surge of attention into a multi-tiered modeling and lifestyle career.

Early Online Presence and Modeling Beginnings (2014–2018)

Karanikolaou started posting consistently on Instagram under the moniker @stassiebaby around 2014. Her early content focused on aesthetic summer photography, beachwear, streetwear style, and candid moments with her close group of friends in Los Angeles. Her distinct fashion sense and natural camera presence attracted attention from emerging direct-to-consumer fashion brands.

By 2016, she was appearing in campaigns for fashion labels such as Oh Polly, White Fox Boutique, Showpo, and PrettyLittleThing. She also gained attention as one of the inaugural faces for Khloé Kardashian’s size-inclusive apparel line, Good American, establishing herself as an in-demand curve and commercial model.

Expansion into YouTube, Major Collaborations, and Cosmetics (2019–2023)

In 2019, Karanikolaou launched an exclusive swimwear capsule with Australian brand TJ Swim, which quickly sold out internationally. She subsequently launched a curated apparel line with Missguided and later partnered with swimwear giant Cupshe in 2023 for a high-profile resort-ready collaboration.

Her YouTube channel expanded her reach beyond static imagery. On the platform, she uploaded travel vlogs, beauty tutorials, Q&A sessions, and behind-the-scenes glimpses of red-carpet events. Her open discussions about personal cosmetic procedures and body confidence resonated with millions of viewers seeking transparency in the digital creator space.

In 2022, she joined forces with Kylie Cosmetics to release the limited-edition Stassie x Kylie cosmetics collection, featuring pastel lip kits, highlighters, and eye palettes celebrating their decade-long friendship. The collaboration highlighted her crossover power between digital influence and retail commerce.

Entrepreneurship with Sunny Vodka and Recent Activity

Recognizing the importance of business equity beyond influencer brand sponsorships, Karanikolaou co-founded Sunny Vodka alongside music executive Zack Bia and spirits entrepreneurs. The brand positioned itself as a modern, corn-based, gluten-free, small-batch vodka made in North Carolina, marketed heavily through music and fashion event activations.

Moving through 2026, Karanikolaou continues to expand her lifestyle portfolio, appearing in front-row presentations at New York and Paris Fashion Weeks, curating hospitality and nightlife ventures, and expanding her commercial endorsements across beauty, luxury streetwear, and global wellness markets.
