Touch Associates recorded a net profit before tax of £242,269 in 2013.
The agency, which launched in 2012, now employs more than 30 staff.
Touch Associates director Patrick Collins said: "We are four months into our new fiscal year and our first quarter saw forecasts exceeded by 25%. We are expecting to see the business sales double, with 35% of the business being creative communications work.
In early 2013, Touch opened its first overseas office in New Jersey in the US.
Director Colette Murphy added: "This was a very brave step for us, but it is a market we know very well and our instincts told us that we could be successful; that business is now growing and will return profits in 2014."
