New figures from IDA Ireland show that over 5,000 jobs in 70 individual investments have been approved here since the Brexit referendum in June 2016.
Companies that have announced Irish investments connected to Brexit include Barclays, Morgan Stanley, TD Securities, Wasdell, Delphi /Aptiv, Simmons & Simmons, S&P Global, Thomson Reuters, Equilend and Coinbase.
Dublin remains the most popular choice for financial services firms to relocate post-Brexit, according to EY's Brexit Tracker.
And a recent report from think tank New Finance said that Dublin alone accounted for 100 compamy relocations because of Brexit.
Dublin was ahead of Luxembourg with 60 relocations, Paris on 41, Frankfurt on 40 and Amsterdam on 32.
IDA executives across the world are hosting events throughout the week to mark Saint Patrick's Day and remind investors of Ireland's strong proposition.
The CEO of IDA Ireland, Martin Shanahan, provided the new figures today as he spoke at the Harvard Club in New York at a conference called "Understanding Brexit".
"These updated figures are another reminder of how our European Union membership and stable pro-enterprise policies are appealing to investors who are looking for certainty," Martin Shanahan said.
"For US companies with ambitions to be global players, Ireland is a natural fit for their international operations," he added.
IDA Ireland has engaged with clients throughout the Brexit process and it said that uncertainty remains on the final business impact of Brexit as negotiations continue.
Increased transaction costs, fears about regulatory divergence and tariffs are amongst the concerns expressed by investors, the IDA said.
