The agency has paid £7m for the deal and will spend a further £12m based on performance over the next 18 months.
Cybercom, an ecommerce specialist, will join DMG’s online media and marketing business segment. Gasbox, a telemarketing specialist, will be part of DMG’s direct marketing segment.
Ben Langdon, Digital Marketing Group’s chief executive, said: "E-commerce represents a substantial growth opportunity and the acquisition of Cybercom strengthens our position to capitalise on it.
"Gasbox will give DMG a new route to deliver and leverage our Digital Brain product. Gasbox’s track record at working with the Group confirms the opportunity to be gained from bringing the companies together.
Gasbox provides a tailored call centre service based on customer data managed by DMG company Jaywing. The company was launched in 2006 by ex Egg chief executive Paul Gratton, along with Andy Gardner and Martin Boddy, founders and current managers of Jaywing. It recently won a Marketing Direct Connect Award.
Cybercom's clients include IBM, John Lewis Partnership, Kickers, Lloyds TSB, Speedo, Thomson Reuters, Tomy and Waitrose.
Terry Hunter, managing director of Cybercom Group UK said: The company has grown profitably for several years and, with the continued forecast expansion of e-commerce, we see many opportunities for this growth to continue.
Chris Hancock, managing director of Gasbox said: Our consumer voice expertise and growth ambitions are a natural fit with DMG; highlighted by our recent award win for a campaign that used Digital Brain. I look forward to the opportunity to grow our business and proposition as part of an organisation that is at the cutting edge of marketing.
