Software Development Slough, Berkshire 1,001–5,000 employees Privately Held

IRIS is a 1,000+ person, UK-based software company serving accounting firms, employers, and schools across 135 countries. The active project list reveals a company mid-transformation: cloud migration and GenAI integration sit alongside foundational work (payroll compliance, data migration, client onboarding). Pain-point clustering around payroll errors, tax deadlines, and compliance risk suggests the core business is still anchored to manual, deadline-driven processes—areas where automation and AI tooling can unlock significant value.
