This software licensing powerhouse's double-digit growth run has shown no signs of abating since its flotation on the London Stock Exchange in 2020.

Bytes' gross invoiced income rocketed by over a quarter to hit £1.208bn in its year to 28 February 2022, with software up 26 per cent to £1.14bn, hardware up 20 per cent to £29m to and services growing by 24 per cent to £43.3m.

This was more than matched at the bottom line as operating profit swelled 57 per cent to £42.2m.

The Leatherhead-based outfit has continued in a similar vein in its fiscal 2023, growing GII by 23 per cent to £786.2m in its first half to 30 September 2022 (underpined bycustomer appetite for security, cloud adoption, digital transformation, hybrid datacentres and remote working solutions).

It won almost 300 new customers during the period.
