33. ANS

Revenue: £119m (+25.5%)

Staff: N/A

ANS is another high-growth firm on the list this year, having jumped from £92.1m last year to £129m in revenue this year.

The Manchester-based cloud specialist grew revenues partly off the back of the Preact acquisition it made in 2022.

It spent much of this financial year integrating the ANS and UKFast entities, which now operate under the ANS banner, as well as integrating Preact.

All this under the leadership of Richard Thompson, who was appointed CEO in October 2022.

The transformational year, however, came against the backdrop of the talent shortage, which ANS cites as a major factor in its accounts.
