1. Vespertec

Revenue growth: +201%
Revenue: £66m
Oxygen 250 ranking: 78
Vespertec is “like Aldi” in the sense that it has adopted relationships with ODMs such as GIGABYTE and Supermicro rather than the likes of HPE and Dell, its Alliances Director Scott Constable told us in September.
Counting MSPs and hosting organisations among its key customers, the Manchester- based server, network and storage integrator trebled revenues to £66m in its year to 30 April 2024.
Pre-tax profits hit £1.9m.
In the small time since Oxygen 250 2026 went live, Vespertec filed fiscal 2025 accounts showing revenues more than doubling again to £142.6m, driven by “specific circumstances that are not expected to continue”.
“Accordingly, the Directors expect turnover in the next financial year to revert to a lower level that is consistent with the Company’s sustainable underlying rate of growth,” it stated in its accounts.
Oxygen ice-breaker:
Vespertec was last April crowned Northern European Star Performer at NVIDIA’s Partners Awards.
