Top Track 250

Some 120,000 customers, including 21,000 accountancy practices and 11,000 schools, use this firm’s software, which supports the accounts, human resources and payroll departments. In 2018 the Berkshire company was bought by Hg and Intermediate Capital Group for £1.3bn, in what was reportedly the UK’s largest private equity-backed buyout of a software firm. Chief executive Elona Mortimer-Zhika, 40, leads the group, which last year made five acquisitions. During lockdown, Iris rapidly updated its payroll software to accommodate emergency legislation, including furlough and sickness benefits.
