Lexis has completed the acquisition of fellow PR and social media marketing agency Paratus Communications.
Paratus, set up by John Rivett and Dominic Shales in 2003, boasts clients including Costa Coffee, AXA and Sainsbury's. Its 11-strong team will move into Lexis's office in London.
Lexis declined to disclose the value of the deal when asked by The Drum.
Jason Gallucci, CEO of Lexis, said: “Whilst both company names derive from ancient language and combine to mean 'Prepared Words' this is very much an acquisition that helps us to continue to deliver award winning campaigns today whilst exploring the future power of 3rd party endorsement across all channels."
The deal sees Rivett become head of consumer at Lexis and Shales become head of content, creative, planning and digital.
In a joint statement Rivett and Shales added: “We are very excited about joining Lexis and the Next 15 group of companies. The last eight years at Paratus have been an amazing experience, from starting the company to growing it through our work with some fantastic businesses. Now is a great time to move to the next level by joining forces with such a respected established agency. It's going to be very positive for our team and clients."
