Louise Clifford, Sally Bett, Denise Palmer-Davies and Chloe Gibson have launched Borne Media in the wake of the Max Clifford Associates founder being sentenced to prison for eight years in May.
The four directors and equal shareholders open the new business today with former Max Clifford Associates client The Only Way Is Essex celebrity Lauren Goodyear on their books.
Other clients include TV presenter couple Angellica Bell and Michael Underwood, as well as George Gilbey, who found fame through Channel 4 programme Gogglebox.
Bett told PRWeek: "We always had a very strong team and to have it snatched away from us in a way that was out of our control was pretty upsetting for all of us. We’ve been highly respected in the business for a long time and didn’t want to go our separate ways.
"We see ourselves as following in his [Max Clifford's] footsteps in terms of the business and building its reputation."
Clifford founded Max Clifford Associates in 1970 and in the early years worked for clients including Frank Sinatra and Marlon Brando. He went on to develop a line in brokering kiss-and-tell stories for tabloid newspapers and helped bring down Conservative ministers David Mellor and Jeffrey Archer.
In recent years he represented a number of showbusiness and business clients including Big Brother contestant Jade Goody, music mogul Simon Cowell and Boux Avenue, the lingerie chain owned by Dragons' Den businessman Theo Paphitis.
The 11 counts of indecent assault he faced, of which he was found guilty of eight, were alleged to have taken place between 1966 and 1984 and involved seven women aged between 14 and 19 at the time of the offences.
The sentence followed two weeks of jury deliberation and a trial in which Louise Clifford appeared in court as a witness for her father's defence.
