Clare Bronfman, 39, a philanthropist and former equestrian show jumper, is the daughter of Edgar Bronfman, the late Canadian chairman of liquor giant Seagram whose net worth was estimated at $2.6 billion.
Bronfman appeared before a judge in Brooklyn, New York and was released with an ankle bracelet after prosecutors argued she was a flight risk.
She was a member of the executive board of Nxivm, a purported self-help group accused of presiding over a secretive society of women sex slaves that shot to notoriety for its initiation rites branding them with the founder's initials.
She is accused of using her wealth to fund Nxivm, and is charged with racketeering conspiracy, which carries a maximum sentence of 20 years, and identity theft with a statutory maximum sentence of 15 years.
Her lawyer, Susan Necheles, said her client "did nothing wrong."
"Nxivm was not a criminal enterprise but instead was an organization that helped thousands of people," she added in a statement.
Three other women, also from Clifton Park, New York were arrested and charged, and similarly entered not guilty pleas, prosecutors said.
Prosecutors also unveiled further charges against Keith Raniere, 57, the Nxivm founder already charged with sex trafficking and forced labor conspiracy.
Raniere, who was arrested in Mexico in March, is accused of creating a secret society called "DOS" -- a pyramid scheme of women "slaves" and "masters" with him -- the sole man -- at the top.
Prosecutors had branded Bronfman an "extraordinarily high" flight risk owing to her vast wealth, access to a private jet, ownership stake in a private island in Fiji, and because her mother and sister live overseas.
Allison Mack, a television actress, was also arrested in April on sex trafficking charges for allegedly recruiting women to the purported mentorship group, whom US prosecutors say were forced to have sex with its leader.
Members were allegedly treated as slaves -- branded with Raniere's initials while being pinned down naked and filmed at initiation ceremonies.
Some were forced onto low-calorie diets as Raniere preferred exceptionally thin women, and none were allowed to sleep with anyone but him, prosecutors said.
