The Graham family, who founded the Glasgow-based firm more than 20 years ago, bowed out last month after the firm was sold to business software giant Sword Group for an eight-figure sum.
Now the legacy of the Grahams – former managing director Iain and his wife, Sheena, – has been wiped from the firm's name as well as its board.
The Ciboodle software package is used in the call centres of large firms including Scottish Water, Vodafone and Friends Provident.
Mike Hughes, the business unit director at Ciboodle, said: "Graham Technology is a name synonymous with quality and success, but Ciboodle represents the future of this company."
Sword yesterday revealed it has snapped up another Scottish acquisition, Aberdeen-based Technology Managers.
The buyout is Sword's second Scottish acquisition in two months and brings the French group's staff in Scotland to more than 500.
