A total of 445 jobs are to be created in 24 new start-up companies which have been supported by the Government through Enterprise Ireland.
The companies, which are located nationwide, say they are committed to creating the jobs over the next three years as part of Enterprise Ireland's High Potential Start-Up programme.
The companies recruiting are involved in clean technology, life sciences and financial services, as well as information and communications technology.
Almost 200 jobs will be created in Dublin. The remainder will be located in counties Clare, Wicklow, Waterford, Offaly, Cork and Kildare.
Minister for Jobs, Enterprise and Innovation Richard Bruton has said the establishment and growth of these new companies could provide the basis for Ireland's economic recovery.
