European digital marketing agencies LB Icon, Framfab and Wheel Communications were relaunched as LBi in September.
Mantra PR was hired as Wheel Communications' retained UK agency at the start of this year and bagged the LBi business off the back of this work.
‘We will initially be concentrating on media relations and building LBi's profile in national and business press,' said Mantra MD Debbie Wosskow.
Stockholm-based LBi has ten offices based across the globe.
ALSO... Mantra spin-off agency Fundamental has announced a raft of new accounts: Israeli mobile company Fring, Indian mobile applications and billing services firm Tanla Mobile, and Cambridge-based Ubisense, which provides systems to help businesses locate people and goods.
