Software and consulting company First Derivatives said it has placed 840,000 new shares to raise about £4.74m sterling.
The company said it made the move to satisfy strong investor demand after it unveiled its annual results earlier this month.
It added that the subsequent investor road show undertaken by the firm was ''significantly oversubscribed''.
First Derivatives said the proceeds of the placing will be used to supplement its working capital requirements as it continues its rapid growth.
''This placement has seen us continue to widen our shareholder base as part of the continuous development of the group, with the oversubscription being a great vote of confidence in First Derivatives and the management's strategy going forward,'' commented the company's chief executive Brian Conlon.
