[4] Einbinder graduated from Beverly Hills High School[5] and went on to study broadcast journalism at Chapman University before earning a Bachelor of Fine Arts degree in television writing and production.

[6][4] At Chapman, Einbinder joined the school’s improv team and had her first experience with stand-up comedy when she opened for Nicole Byer for a campus show.

[4][5] In 2019, Einbinder appeared in the Just for Laughs festival's New Faces showcase and was named by National Public Radio as one of the 10 standout comedians to watch.

It was the show's last on-stage stand-up performance for fifteen months, as the COVID-19 pandemic began soon after the episode aired.

[19] Einbinder has cited Dana Gould, Janeane Garofalo, Bo Burnham, Maria Bamford, Sklar Brothers, Marc Maron, and Steve Martin as being among her inspirations and influences.
