The new jobs will be in the areas of software, sales and support.
The company's growth - which is supported by the Department of Jobs, Enterprise and Innovation through IDA Ireland - is being accommodated by a new office in Dublin's docklands.
The new office is located near HubSpot's existing EMEA headquarters at North Quay Wall.
The company's Managing Director in Dublin, Christian Kinnear, explains that they decided to set up and grow the company in Dublin for many reasons, including the talent pool here and IDA support.
JD Sherman, HubSpot President & COO, said, "HubSpot’s Dublin-based team has been core to so much of the success that we’ve seen as a company around the globe over the last three years and I am so excited for the successes that are yet to come".
The announcement was welcomed by acting Jobs Minister Richard Bruton, who said, "HubSpot is a highly innovative company in a fast-growing niche within this sector, and it was clear when we first met in Boston in 2012 that they had highly ambitious plans for their Dublin expansion".
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.
