Two hundred new jobs are to be created in Dublin over the next two years by productivity platform, ClickUp.
The US technology firm is to open a new European headquarters here as part of its international expansion.
The new roles will be in a range of areas including sales, customer success, marketing, support, finance and HR and recruitment has already begun.
The expansion comes just over a month after the San Diego headquartered business raised $400m in Series C funding.
ClickUp said it chose Ireland because of the established technology community here and availability of talent.
"We have been impressed by the deep expertise and great supply of multilingual tech talent in and around Dublin, and we see our European office as playing a vital role in ClickUp's continued global expansion," said Mark Stoddard, Head of International Operations at ClickUp.
"We’re excited to bring ClickUp to Ireland and provide a diverse range of jobs, while adding to the already world-class tech community."
Founded in 2017, ClickUp is an all-in-one software as a service platform that replaces individual workplace productivity tools with a single platform that includes project management, document collaboration, spreadsheets, chat, and goals.
It counts among its customers Booking.com, Netflix and McDonalds and is used by 800,000 teams globally, 275,000 of whom are based in Europe.
The company plans to use its Dublin office to localise the product for its customers in France, Germany and Spain.
The investment has been welcomed by the Tánaiste and Minister for Enterprise, Leo Varadkar, and by IDA Ireland which has supported it.
"Dublin remains a leading destination city for fast growing companies to set up their European HQ in order to internationalise their business and to serve and grow their customer base," said Martin Shanahan, CEO of IDA Ireland.
"Ireland has a proven track record of being a very attractive location to Software as a Service (SaaS) companies looking to access a well-established talent pool to scale quickly.
ClickUp has tripled its revenue in the last year and quadrupled its number of users.
In total it has raised $535m in funding and is currently valued at in excess of $4 billion.
