Cristine Rotenberg is a remarkable woman. After moving on from a career as a child actress, she built an enormous online audience for her nail-art YouTube channel, Simply Nailological, becoming one of the most popular YouTube channels in Canada. In 2022, she gave it up to focus on her nail polish brand, Holo Taco, which has sold more than 1 million bottles. If that wasn’t enough, she also runs multiple other channels AND works full-time for the Canadian government as an analyst.

Born in Ontario in 1988, Rotenberg was an actor until she was 12, appearing in films and more than a dozen television commercials. She gave up to focus on school and would ultimately earn a master’s degree in sociology, leading her to her day job as an analyst for Statistics Canada. She launched her nail art blog, Simply Nailological in 2014, and along with her other channels, such as Simply Not Logical and Simply PodLogical, she has now amassed more than 2 billion YouTube views. A simply amazing feat.

Given her success as arguably the world’s most popular nail-art vlogger, it’s unsurprising that Rotenberg launched her own brand of nail polish, Holo Taco, which launched in 2019 and focuses on special effects such as holographic and iridescent polish. Within three years, sales figures hit 1 million and are still going strong today. Rotenberg still regularly posts online content, but her focus now is growing Holo Taco. Given her incredible success — whilst still working for the government — she’ll succeed sooner rather than later.
