IRIS Software Group
Founded in 1978, IRIS began as a supplier of accounting and payroll software to small and mid-sized UK practices. Kevin Dady has been CEO since 2013, steering the group through multiple private-equity ownership cycles — including its current backing by Hg, the London-based software specialist that took a majority stake in 2018 alongside Intermediate Capital Group. The wealth origin is institutional, rooted in a buy-and-build strategy rather than a single family's capital. The firm's strategy is a textbook vertical software consolidation model, focused on four core pillars: accountancy, payroll and HR, education, and healthcare. IRIS provides a suite of mission-critical products — from tax filing (IRIS Elements) and practice management to school management information systems and clinical compliance tools. Confirmed positions in its portfolio include PS Financials, a cloud accounting platform, and KashFlow, a small-business bookkeeping tool. The firm's geographic footprint is heavily concentrated in the UK, where it serves over 100,000 businesses, though select products reach English-speaking professional services markets. Hg and ICG have backed a continuous wave of bolt-on acquisitions. In September 2023, IRIS acquired Tracie Wright Limited, a UK-based education payroll specialist, adding niche payroll capabilities for the teaching sector. In recent years, the group has averaged over a dozen tuck-in deals annually, building density within its existing verticals rather than expanding into new categories. The firm's scale is embedded in its installed base, with its accountancy software used by the majority of the UK's top 100 firms. IRIS's structural differentiator is its role as the de facto compliance backbone for UK accountants. When regulatory changes roll out — such as Making Tax Digital — IRIS's customer base must adopt updates or risk non-filing, creating a semi-captive demand cycle. This regulatory tailwind, paired with the private equity roll-up engine, gives the firm a recurring revenue profile that behaves more like a utility than a discretionary software vendor.

Frequently asked questions
Who owns IRIS Software Group and how is it financed?
HgCapital, the London-based private equity firm specializing in software and services, has been the majority owner since 2018, acquiring the business alongside Intermediate Capital Group. The firm is institutionally financed through private equity with a capital structure designed to support its continuous bolt-on acquisition strategy, not family wealth.
How does IRIS's revenue model create a competitive moat?
IRIS provides software that handles statutory compliance — tax filing, payroll processing, and regulatory reporting. When the UK government mandates changes like Making Tax Digital, the entire customer base must update their software to remain compliant, which generates a recurring need for the latest IRIS platforms. This regulatory integration makes switching costs exceptionally high for practices.
What is IRIS's acquisition strategy under HgCapital?
IRIS operates a vertical-specific buy-and-build strategy, acquiring small, established software vendors in its four core verticals — accountancy, payroll, education, and healthcare — and integrating them into its broader platform. The firm typically targets niche providers with strong client retention, bolting them on to gain density rather than completely reinventing their product.
Which sectors does IRIS explicitly target for its software solutions?
IRIS focuses on four regulated verticals where compliance workflow is mission-critical: accountancy and tax, payroll and HR, education management, and healthcare provider operations. The firm invests heavily in staying current across these sectors, which depend on IRIS for day-to-day legislative compliance.
Is IRIS a single-family office or does it seek third-party investors?
IRIS is not a family office. It is a private-equity-backed operating company majority-owned by HgCapital, with institutional co-investors. Its capital comes from limited partners in Hg's funds, and it operates as a standalone business serving professional-services organizations.
