Our mixed fortunes with firms like this
The case of software firm Revel Systems isn't the first time a US technology firm has failed to deliver on its promises here.
Silicon Valley company Vello Systems opened up a new office in Belfast's Cathedral Quarter in 2014, where around 70 staff were set to work in research and development.
But just two months after launching, the firm cut around 15 staff from its workforce.
The proposed 71 posts would have created more than £2.4m in salaries each year for the economy, it was claimed.
And there were high hopes for Revel Systems during the Belfast launch of what was due to be its European headquarters back in December.
It's a multi-million dollar company at the forefront of using iPads to make payments.
And it has also been working closely with Apple to bring features to its point of sale customers, growing the company to more than 300 staff.
At the time of the launch, Employment Minister Stephen Farry said it was "encouraging that the skills levels in Northern Ireland are such that we are attracting innovative and rapidly expanding companies".
While Enterprise Minister Arlene Foster said she was "delighted" at the announcement.
On his visit to Belfast, Chris Ciabarra, co-founder of Revel Systems, said the company was "confident" it would find "dynamic employees with real entrepreneurial spirit" here.
