Specialised cloud service providers, a cloud consultancy and a cloud-based distributor are among those included in this year's Sunday Times Hiscox Tech Track report, which is an annually published list of the UK's fastest-growing private technology companies.
Rankings are based on the company's average sales growth over the last three years of trading.
The report excludes "pure computer resellers", and IT consultancies and services companies are required to generate a "significant portion" of their sales from proprietary technologies in order to be included on the list.
