Operating profits for the Milton Keynes-based agency grew from £1.1m in 2014 to £2.5m, while sales increased by 38% to record levels, growing from £32.2m to £44.5m.
Gross profit was also up, from £9.4m to £12.5m, representing a 33% rise.
Mike Davies, managing director, said: ""Every single member of our team deserves this result. Their determination, talent and sheer hard work has delivered an exceptional result.
"We continue to proactively search for suitable acquisitions, although with this level of exceptional organic growth we will continue to be very cautious in selecting the right companies to buy."
In the last 12 months, the agency has grown its headcount to more than 210, as well as expanding into Russia and Germany.
"At the heart of our strategy is our people. Achieve that and the numbers fall into place. Our staff turnover rate is very low at just 11% and we are actively recruiting for between 15 and 30 new positions this year," Davies added.
