This LSE-listed software licensing, cloud and security giant has “a very ambitious growth target for the next few years and is planning accordingly”, CEO Sam Mudd told IT Channel Oxygen last May as it broke the £2bn top-line barrier.
Gross invoiced income (GII) for its year to 28 February 2025 powered up 15.2% to £2.1bn, with growth by our calculations accelerating from 13.7% to 15.8% half-on-half. Gross profit pogoed 12% to £163.3m and operating profit by 17.1% to £66.4m.
A recent sales restructure – along with incentive changes at largest vendor partner Microsoft – dented BTG’s first-half 2026 numbers, although Mudd claimed it built “positive momentum through the period”. 1H GII still rose 9.1% year-on-year to £1.34bn.
BTG’s two sub brands – Bytes Software Services and Phoenix Software – employed 760 and 477 staff, and had 3,204 and 2,709 customers, respectively, at year end. Key vendors besides Microsoft include AWS, Palo Alto, Check Point, Mimecast, Adobe, VMware, Dell and Sophos.
Oxygen ice-breaker
For Phoenix Software, the customer is king – literally… In May 2025 it bagged a Royal Warrant for Supplier of IT Managed Services after serving the Royal Household for five years.
