Technology firm Kelsius has landed a six-figure deal with top-end US burger chain Five Guys.
Kelsius, which has offices at the Catalyst business park in Belfast as well as Donegal, makes wireless temperature monitoring technology for product safety and compliance.
Spending approximately £60,000 on research and development to secure the deal, Kelsius is now supplying 50 Five Guys locations across the UK, including Belfast's Victoria Square outlet.
The Desmond brothers, sons of Irish billionaire Dermot Desmond, opened their first Five Guys restaurant in Northern Ireland at the Victoria Square complex last year, creating 55 jobs.
Kelsius says the FoodCheck system temperature monitoring technology "maximises product safety, which ensures regulatory compliance in this very complex area".
And it also cuts down on costs, thanks to the automation.
Kelsius chief executive Andrew Logan said: "The Five Guys deal is a massive boost for our company and it's a real testament to the strength of our product within the food safety sector.
"We now feel it has given us more confidence to attract customers of a similar size and reputation as Five Guys.
"We are well known in the Irish market, after previously winning contracts with Musgrave Supervalu Centra and Applegreen, but this deal has helped us broaden our customer base in the UK and with the support of our global partners further afield."
William Day, UK IT director for Five Guys, said: "The FoodCheck paperless HACCP system is easy to use, allowing staff to concentrate on the quality of food we provide. Records are easily and securely accessed for each location and the reporting is what really sets the system apart. This makes life much easier for a HACCP audit or inspection."
Founded in 2003, Kelsius has a network of partners in Europe, the Middle East, Australia and US.
