Both brands will continue to operate separately as part of the enlarged Red C Group, which will be led by Red C’s MD Richard Colwell (pictured).

He said: “We are delighted to have come to an agreement with OI Research, and to bring them into the larger merged Red C Group. I have known David Cullen, MD of OI Research, for a long time and have always valued his skills and abilities, and believe he has very much instilled these in his team.

“OI Research have been at the forefront of bringing new techniques and ideas to Ireland, and this will further cement our position as the leading innovators in insight delivery.”
