CIS, the Dublin-based construction information services provider has acquired Belfast-based Unearthore, its main competitor.
While the terms of the deal have not been disclosed, it is believed that the consideration may have been over €250,000.
CIS supplies construction related firms with planning and project data used to compile sales leads, build profitable marketing/sales plans, and win new business.
Unearthore, (formerly, Commercial Information Company), has been a major player in the NI market since 1980 and was owned by Pat McGrath who is joining CIS.
CIS managing director Tom Moloney expects the move will help to increase the firm's turnover by 20pc this year and help develop a market in Scotland as well as in Northern Ireland.
Despite a challenging market, CIS have already this year shown the signs of a return to growth for the first time since 2007. "Already, sales this year are up 39pc ," Mr Moloney says.
CIS will be taking on two new staff at their Sandyford offices in Dublin 18, and the company anticipates further openings this year.
