Dock10 commercial director Ian Munford has left the post production and studios company.
Munford, who joined Dock10 in October 2011 from BT Media, left the MediaCityUK facility at the end of last month.
A spokeswoman said Dock10 had no plans to recruit a replacement.
Munford said: “I’ve had fantastic time at Dock10 and I feel privileged to have worked with such a great team.
“I’m proud of what the business has achieved, building a thriving ‘go to’ media business from scratch in such a short space of time, but the time is right for me to take on a fresh challenge.
“I have no doubt that the business will go from strength to strength and I wish everyone at Dock10 the very best for the future.”
