Archangels first invested in Critiqom in 2005 and since then the company has grown to become a national provider of a variety of complementary document mailing solutions, including an end-to-end suite of data, print, post and multi-channel services.

The business is headquartered in Bellshill, North Lanarkshire, with manufacturing operations both at Bellshill and in Warrington, Cheshire.

Opus Trust Communications, headquartered in Leicester, provides multi-channel digital, print and postal solutions, designed to support business communication strategies and drive customer engagement. The acquisition price is not being disclosed.

Niki McKenzie, investment director at Archangels, said: “Critiqom has been a valued member of the Archangels portfolio for many years and it is clear that its next strategic step forward should be as part of Opus Trust Communications. We wish the whole Critiqom team further success as they embark on the next stage in the company’s development.”
