59. ANS

Key points

Revenue: £62.7m (+36%)

Net profit: 14.2%

Staff: 260

A lack of new accounts for this Manchester-based Cisco Gold and Advanced AWS partner means we have had to recycle last year's numbers, which showed a net profit of £8.9m on revenues that rose 36 per cent to £62.7m for its year to 31 March 2017. Last December, ANS acquired cloud transformation and application development firm Webantic. It now claims to have more than 300 Microsoft and AWS certifications, equal to its tally of customers.
