The search is on for Northern Ireland's fastest growing technology companies for the 2014 Technology Fast 50 awards, established by business advisory firm Deloitte.
The awards, now in their 15th year, honour the best of the indigenous technology sector and recognise exceptional growth in turnover during the past five years.
In addition to the Fast 50 ranking, the Rising Star category will award two up-and-coming companies established less than five years ago.
Northern Ireland companies performed well last year, occupying 18 spots, an increase of three on the previous year.
In last year's round, Belfast-based insurance comparison company Seopa was placed in the top 50 for the third consecutive year.
David Crawford, partner at Deloitte in Belfast, said it was very encouraging to see Northern Ireland companies perform so well last year.
"It is testament to the strength and innovation of our indigenous technology firms and to the growth potential of the industry," he said.
