Babel has also announced it is adding two new Cambridge-based clients to its roster; international Internet of Things platform provider Podsystem and merchant payment specialist CashFlows.
The new office will be supervised by director Matt Humphries, who will split his time between Cambridge and London, and managed on a day-to-day basis by senior consultant Andy Eldridge.
"The area has proved itself as a hotbed for international companies looking for a UK presence outside of the capital, in addition to the raft of innovative start-ups emanating from the University of Cambridge," said CEO Ian Hood.
Cambridge’s status as a prominent UK tech hub was reinforced further last month with the announcement that Japanese tech giant SoftBank was shelling out $32bn for Cambridge firm Arm Holdings.
Last March, Babel brought in former Golin exec Caroline Kawashima to lead its San Francisco operation as it branched out into the US. Before that, the specialist in b2b comms for the mobile and telecoms sector had a presence in Silicon Valley with freelancers, but wanted a more substantial presence overseas.
