Royalblue Group Plc, a UK financial and helpdesk software company based in Woking, Surrey, is continuing its push into US and European markets, and saw its US revenues double to 5m pounds when it reported its year-end figures yesterday. Overseas sales now account for 20% of the total. This helped it increase net profits for the year by 50% at 2.8m pounds on revenue that rose 180% to 29.5m pounds. Continued success in the US is vital for the company long-term and it has the considerable advantage that it has little direct competition in financial trading systems software in its drive to oust legacy systems. Europe is a market just opening up to Royalblue and the advent of the euro has added to pressure for a pan European share trading system where its products can score heavily. Apart from the financial software, which showed a 41% growth in sales and now accounts for just over half of group revenues, Royalblue’s other boom area has been customer interaction software which showed 61% growth. The one flat spot has been in the call center business where slack demand was blamed.
