The live events and brand communications agency said it was delighted to report "outstanding" figures for the last financial year.
Nick Robinson, managing director at Concerto Live put the positive results down to several factors, including key account management and "some important client wins".
He added: "We have ambitious plans to continue to reinvest in the business in terms of quality talent, research and technology innovations, so are expecting an even more exciting year this year."
Sean Doyle, head of creative services at Concerto Live, said: "We’ve always committed to put creative thinking and innovation at the heart of everything we do as an agency as we believe that, along with operational excellence this would set us apart.
"We’re delighted that this is a formula that is clearly paying off, not only demonstrated by these excellent financial results but with the fantastic talent we’re attracting to the agency and the great brands we’re getting the opportunity to talk to."
The agency recently hosted Inspiration Station Live at new event space, Landing Forty Two at the Leadenhall Building in London - a showcase evening for some of its event technology suppliers. The evening attracted more than 200 guests from companies including Nike, Topshop, Adobe and Getty Images.
