More than 50 new jobs are to be created in Co Down, Arlene Foster announced.
Mango Direct Marketing - a Bangor-based telemarketing company which has customers in the US, Australia and Israel - said it plans to increase its workforce by 55.
During a visit to the company's call centre, the Enterprise Minister said the expansion showed a commitment to Northern Ireland.
"Mango is a successful business that has achieved a steady increase in sales over the past five years.
"The jobs are being supported by Invest NI Jobs Fund and will enable Mango to take on major new contracts in its key target markets. The business services sector is an important driver for the economy and it is encouraging to see companies investing in growth even in these difficult times," said Mrs Foster.
Invest NI has offered Mango Direct Marketing £165,000 of support through its Jobs Fund.
Stuart Lally, managing director of Mango Direct Marketing, said: "Our strategy for growth includes investing in our current staff training programmes and company structures whilst also increasing our share of the niche markets in which we currently work.
"Support from Invest NI through the Jobs Fund will also enable us to put in place the staff we need to take advantage of new business opportunities in the corporate sector and cement our competitive position in key markets."
