Claire Bridges - formerly Claire Mann - left Cohn & Wolfe last July with no job to go to.
She is now launching Agency for Agencies (A4A), which will form part of integrated agency White Label, founded by former Cake directors Drew Shannon and Greg Saunders.
Shannon and Saunders founded White label in 2001.
Bridges said: ‘We're setting up to provide creative services and resources for PR agencies and brands - a gap in the market that I think has massive potential given how agencies are stretched.
‘Services will include brainstorm facilitation, idea generation, creativity training and "pitch bitch" resources, strategy development, killer ideas and presentation writing.'
Bridges worked with Shannon and Saunders at Cake as board account director from 2000-03, before leaving to join the board at Cohn & Wolfe.
