The economic investment conference last week was the "most successful" of the three which have been held, First Minister Peter Robinson has proclaimed.
He said he and Deputy First Minister Martin McGuinness have now been involved in a trio of investment conferences including the 2008 Washington event organised by then US Secretary of State Hillary Clinton.
But he said he and Mr McGuinness were "both agreed that, in respect of the contact that we have had with investors, this was by far the most successful conference that we have had."
The DUP leader said the response was "very positive" among those who attended a dinner at Hillsborough Castle on Thursday evening and added: "It is that kind of networking that really gets a connection with business people.
"It is an opportunity to find out what projects various companies are looking at and, therefore, how we might fit into their needs and requirements.
"At that dinner, we spoke to a number of people – the Deputy First Minister at his table, and me at mine – who are looking at Northern Ireland as a possible place for investment.
"It was encouraging to find out the next day that a lot of companies that had Northern Ireland on their shortlist were indicating that Northern Ireland had now leapfrogged to the top of their shortlist," he said.
"That indicates how successful the investment conference was."
Mr Robinson and Mr McGuinness visited Invest NI offices yesterday to thank the team.
