Hampshire-based business comms provider OneCom grew to 180.4m revenue in its most recent filings, thanks to both acquisitions and organic expansion.

The MSP is on a mission to shift from a mobile comms specialist to a unified comms proposition, it says in its annual accounts.

LDC-backed OneCom touted investment in digital interaction and self-service capabilities through its OneCloud platform as a key investment during the post-pandemic period.

Notable wins include 5 per cent year on year growth in its cloud customer base.

OneCom also managed to increase its average revenue per customer by 15 per cent.
