IRIS Software Group was created through the merger of IRIS Group Limited and Computer Software Group, two of the UK's market leading vertical application software and services companies. Today, IRIS is the leading provider of industry-specific software solutions to accountancy practices, law firms and not-for-profit organisations in the UK as well as providing a variety of related software solutions to small and medium sized companies more generally. In 2007, HFCP VI completed a £500 million buyout of the two companies.
