Air-IT is set to diversify and pursue faster growth following a revamp of the management team.
Founder and MD Todd McQuilkin has moved to the CEO role while Technical Director James Healey becomes MD from 1st September.
McQuilkin said: "James has been an integral part of our journey having been by my side every step of the way.
"We've experienced significant growth, consistently reporting over 20% increase year on year and to top it off in my final year, we're expecting an increase of 30% or more."
Air-IT was established in 2005 when McQuilkin invested a £20,000 redundancy payment from his previous position as Head of IT at Femcare Nikomed.
Initially, the business operated out of residential cottages in Nuthall, Nottinghamshire, and Healey was recruited as the first member of staff in a leading technical role.
In 2013 Air-IT acquired local telecoms provider Managed Business Communications (MBC), enabling it to offer a full portfolio of IT and Communication services under one roof.
Healey added: "Having been on board since day one I have seen the company experience significant change and high growth in an industry that's fast paced and always evolving. I'm eager to continue this journey."
As CEO, McQuilkin will continue to drive Air-IT's business strategy, heading up a new venture under Air-MSP Consultancy which is aimed at helping others in the ICT service industry benefit from operational improvements.
