Atomic, which won the account following a competitive pitch, has been briefed to raise awareness of the environmentally friendly private hire company amongst consumer and business audiences.

The team will work across consumer, digital, social and corporate media to promote greentomatocars as London's alternative private hire minicab service.

Jonny Goldstone, MD at greentomatocars, said: "We were extremely impressed by Atomic from the outset. Its smart insight and 'out of the box' creativity, underpinned by sophisticated analytics made Atomic stand out from the crowd."

Daniel Cohen, MD at Atomic, said: "We are extremely excited to have been appointed by greentomatocars. They have a great story to tell and we are very much looking forward to bringing this to life and embarking on the journey with them."

Following the win, Atomic has brought in Champion Communications' Sinead O'Conner as an account manager and Frank PR's Josh Hoppen as an account executive.
