[10] In 2014, Rotenberg received a master's degree in sociology with a concentration in criminology from Carleton University.

Her work focused on crime statistics and had included analysis of sexual assault reporting amid the #MeToo movement.

Despite lucrative success with her other endeavours, Rotenberg expressed her desire to maintain her analyst work for reliability and fulfillment not available in her YouTube career.

[15] On YouTube, Rotenberg initially created short nail art videos that were less than two minutes long.

[11][21][22] Rotenberg has three secondary channels: "Simply Not Logical" was created in September 2015 and primarily contains vlogs and live streams.

An April 2020 episode of the podcast featured Mazowita and Rotenberg interviewing Dr. Howard Njoo, the Canadian government's deputy chief public health officer, about COVID-19.

[24] On July 17, 2022, Rotenberg announced that she would cease producing videos for her main channel in order to focus on her personal life and Holo Taco.

[30] Holo Taco has since released numerous nail polish collections, including collaborations with YouTubers Julien Solomita and Safiya Nygaard.

[31] In October 2024, selected polishes from the brand began being sold at Ulta Beauty in the United States.

Despite higher production costs for special effects polishes, Holo Taco's avowed aim is to keep prices as affordable as possible.
