This deal delivers that in one move and provides a first class platform for future expansion both in the UK and overseas. It is excellent news for our customers as it significantly expands our R&D capabilities and service infrastructure as well as providing tremendous scope for career opportunities for our employees. We are delighted to have the backing of Hellman & Friedman to support the next and very exciting phase of our growth."

Vin Murria added: "The combination of IRIS's market leading solutions and highly successful operational capabilities are hugely complimentary to CS Group's M&A driven growth and niche market focus. This is an exciting opportunity to dynamically grow a successful customer centric business that can only be positive for all clients and employees alike. We too are delighted to have the backing of Hellman & Friedman."

Stephen Duckett, Managing Director at H&F said: "Both IRIS and CS Group are exceptional businesses with strong positions in key verticals, high levels of subscription revenue and tremendous future growth potential. They have produced strong organic growth by delivering a high-quality product set and market leading levels of customer service, demonstrated by exceptional customer retention levels. The strategic logic for this business combination is very sound and we have successfully adopted a similar investment approach in the USA vertical software sectors. We see excellent opportunities for further organic growth supplemented by continued complementary acquisitions".

Patrick Healy, head of H&F's business in Europe said "Over our 23 year history we have made over 65 investments and nine investments in software. The IRIS Software Group is a great addition to that roster. We are proud to be associated with world class management like Martin, Neal, and Vin. IRIS will provide meaningful career opportunities to existing and future employees throughout the UK."
