On demand staffing platform, Get the Shifts, has been bought by FRS Recruitment.
The amount paid for the Clare based start-up has not been disclosed, but it is understood that in excess of €1m was paid.
FRS said it will use the acquisition to further grow its market share in the temp market here and to expend into international markets.
Get the Shifts will become a division of FRS Recruitment with Hannah Wrixon becoming General Manager.
"Now that they are part of FRS Recruitment, we believe we can develop strong synergies that will benefit both these operations," said Colin Donnery, General Manager of FRS.
"FRS Recruitment has been experiencing growth across all our core markets and that is a trend we expect will continue."
"This acquisition will provide the opportunity to future proof our ambitions in Ireland and abroad, developing on demand, fully automated staffing solutions that will benefit our clients wherever they are in the world."
Get the Shifts provides on demand temporary personnel for hospitality, retail and marketing clients, at up to 500 staff at a time.
The service is accessed through a platform available on mobile or desktop and staff can be supplied with as little as 3 hours' notice.
"FRS are one of the leading recruitment operations in Ireland and our shared values made it an easy decision," said Hannah Wrixon.
"We have no doubt that they can help us in the next stage of our growth. They have repeatedly proven they are a progressive, growing business with a global outlook."
