More than 1,800 jobs are to be created at new high-tech start-up companies.
The positions at 122 firms will be created over the next three years and are part of Enterprise Ireland's "High Potential Start-Ups" scheme.
The companies will be export-driven, based on "high-tech innovations" and it is hoped all can achieve significant growth within three years.
Enterprise Ireland says it hopes the companies will grow "rapidly" and stimulate local economies and create more jobs in the years ahead.
The Jobs Minister Richard Bruton says it is part of a "determination to boost the employment market with Irish enterprise" and not just multinational companies.
More details on the positions are expected to be announced by Minister Bruton at the official launch later this morning.
