NEW YORK—Finn Partners has reported organic growth of 10% in 2013, with the agency's acquisition of Widmeyer Communications taking revenues beyond $44m.

Finn, which spun off from Ruder Finn in late 2011, grew overall revenues by 37%, with headcount increasing 28% to 298 professionals. Those numbers include the Widmeyer deal, which added around $10m and 40 people to its Finn's New York and Washington DC offices.

Founding partner Peter Finn told the Holmes Report that the agency's collaborative mindset across its eight offices has helped spur growth from both account wins and acquisitions. 

"We expect Finn Partners to continue to grow faster than the PR industry overall, and this growth will be a result of acquisitions, new business wins and growing existing accounts," said Finn. "We are finding that our partnership philosophy, the way we do business, both with clients and our internal staff, creates an immediate comfort level with firms we have acquired and with firms we are in discussions with to acquire."

Major areas of growth included the health services, education and travel/economic development sectors, much of which, said Finn, was won by a combination of teams across offices.   

After opening a London office last year, furthermore, Finn added that further global expansion will likely include other European and Asian markets over the next five years.  

Finn's results follow strong gains at midsize independent peers W2O and Lewis PR, along with a double-digit increase at Edelman.
