Gradwell Communications CEO Simon Mewett and Chief Product & Marketing Officer Julien St John-Dennis have left the business following an MBO and a change of institutional investor.
The move sees the appointment of Nick Caw as CEO and Andrew Peters who becomes COO, both bringing strong experience in the IT and telecoms market.
The company says the new investment group is supportive of its focus on core strengths in calls, connectivity and cloud.
It was also confirmed that Gradwell will further develop its VoIP platform over the coming months and introduce 'positive changes' in customer support, billing and sales processes.
Founder Peter Gradwell remains with the company as CTO.
