West Yorkshire-based Nasstar also made a significant jump in this year's ranking thanks to an inorganic revenue spike of 42 per cent to £161.3m.
The business attributes this to a £57.2m contribution from the acquisition of National Business.
Underlying revenues for this Microsoft, AWS and Cisco partner, meanwhile, were dragged down by the impact of changing customer demands during and after the Covid pandemic.
In September 2023, Nasstar saw another reshuffle to its C-suite with the hire of Kevin Dangerfield as CFO, exactly one year on from CEO Paul Cosgrave coming on board.
