📊 Who are the Tech Titans?

The top 150 public sector-facing tech firms span a broad mix of providers - including IT services, telecoms, hardware, cloud, and cybersecurity firms, as well as a significant number of IT resellers.

Together, they received £16.5bn in direct public sector revenue in FY23/24 - a staggering 84% of all government spending with technology suppliers.

Tussell’s analysis of the Tech Titans reveals that IT resellers have experienced the strongest growth in public sector revenue between FY19/20 and FY23/24.

During that same time period, the share of the group revenue taken by UK-based Tech Titans (who represent a slight majority of the cohort) has slipped from 45% to 42%.
