After a challenging pandemic period, marred by supply chain issues, storage specialist Proact returned to growth in 2022.

The European firm's UK entity reported a 20 per cent revenue spike, despite the negative impact of the final lockdown at the beginning of 2022.

The main sales increases were delivered by the business' traditional reseller business, it said, thanks to tech refreshes towards the tale end of the pandemic.

The integration of acquiree Cetus Solutions' customers also contributed towards this bottom line, as did an 8.7 per cent uptick in managed services.
