Almost 400 jobs have been announced this morning in two separate job announcements.
Dublin will get 320 technology jobs at Hubspot, be based at the company's new offices in the Docklands, and they will be advertised and filled over the next three years.
The new jobs will be in the areas of software, sales and support, at Hubspot's European and Middle East Headquaters in the capital.
The investment is supported by the Department of Jobs, Enterprise and Innovation through IDA Ireland.
Jobs Minister Richard Bruton said: "The growth and success of technology companies has been a major contributor to the recovery we have seen in the jobs market and the economy over recent years."
Meanwhile, the car rental company Enterprise has announced it is creating 75 new jobs as it expands its business in Ireland.
The new positions are to come on stream in the coming year at branches around the country.
They include more than 60 management roles and 15 part-time positions in the customer service department.
