Accumuli chief executive Gavin Lyons has exited the security services firm as its integration into NCC Group nears completion.
Lyons (pictured), along with several other Accumuli executives, has moved onto pastures new seven months after NCC Group snapped up the AIM-listed firm for £55m.
Lyons' last day was Friday, the day after NCC put out a trading update saying Accumuli's integration had been largely completed "ahead of schedule".
"The departure of Gavin and the executive team from Accumuli was a natural part of the business' integration into NCC Group," Rob Cotton, chief executive of NCC Group said in a statement to CRN.
"This integration is now largely complete, with natural homes being found for all the component parts and members of Accumuli's strong senior management team taking senior roles in the combined organisation."
Lyons joined as Accumuli's chief executive in 2012 and under his watch the Splunk and Arcsight partner made four acquisitions and saw turnover swell to £27m.
NCC grabbed Accumuli in a cash and share deal in March, saying the 24/7 operational security support and incident management services it offered would complement its consulting capabilities.
Lyons was unavailable for comment.
