Business telecoms company Rainbow Communications has opened new offices in east Belfast after a £0.25m investment.
The extension was made to accommodate new support and sales teams after Rainbow became the only direct business partner in Northern Ireland for EE's new 4G super-fast broadband.
It also expanded into Scotland in a move which created 20 new jobs, including six at home in Belfast and 14 in a new office in Glasgow.
Newly-appointed Finance Minister Simon Hamilton visited the new offices of the business, which has around 5,500 business customers. Mr Hamilton described Rainbow as "a Northern Ireland success story".
"It's a company that has developed its products and services to ensure its customers benefit from the latest technologies.
"Despite the economic conditions, the directors have invested for future growth, a bold step which is already paying dividends with plans for more job creation later in the year."
Founder and director Eric Carson said: "The company has witnessed huge growth in our mobile offering working in partnership with EE and our expansion into Scotland has also proved a success."
Rainbow employs 80 staff and offers calls and lines, mobiles, broadband and IT services.
