Riverdeep finished top of the heap in the Deloitte & Touche Fast 50 awards that were handed out in Dublin last night.
Riverdeep, the education software firm with headquarters in Dublin and Massachusetts, has been one of the few companies to thrive during the recent tech slump and has recorded growth of 14,193 per cent over the past three years.
The awards recognise and rank the fastest-growing tech companies in Ireland over a three-year period.
Riverdeep will now be invited to participate in a Deloitte & Touche Fast 500 conference, due to be held in the US later this year.
Directory services firm Conduit came second, recording growth of 949 per cent.
