An Israeli intelligence company has apologised for its work with disgraced film mogul Harvey Weinstein, pledging proceeds will be donated to women's groups.

The New Yorker reported Weinstein had hired Black Cube, which markets itself as a group of ex-members of Israeli intelligence units specialising in business and litigation challenges, to help stop the publication of abuse allegations against him.

"Of course we apologise to whoever was hurt by this," said Asher Tishler, a member of Black Cube's advisory board, during a TV interview on Israel's The News.

"In retrospect, it's a shame we took the job."

Mr Tishler said he was not familiar with all the details of the work Black Cube carried out for Weinstein.

One account in The New Yorker article described two private investigators from Black Cube, using false identities, meeting with actress Rose McGowan to extract information from her.

The Charmed and Scream actress has accused Weinstein of sexual assault.

"I think the job was taken in a justified manner. When it was discovered there was a problem, they stopped," Mr Tishler said.

He added that any money the company made would be given to women's groups.

More than 50 women have alleged that Weinstein sexually harassed or assaulted them over the past three decades.

Actresses Angelina Jolie and Gwyneth Paltrow were among the women speaking out against the disgraced film mogul.

Weinstein has denied having non-consensual sex with anyone.
