Jones first worked for Sky News as a freelancer in 1999 before becoming a full-time member of staff in 2002, and joining the political team in 2007. He then rose to be deputy political editor before leaving last month to join Osborne & Partners.
At Sky, major scoops included breaking the stories of the resignations of Jacqui Smith and Hazel Blears, and he also shadowed David Cameron throughout the 2010 general election.
The firm, which has minimal public profile, describes itself on LinkedIn as "an international strategic advisory firm providing governments, corporations and high profile business and political leaders with discreet strategies designed to enhance their reputation, credibility and profile on a global basis".
The agency, founded by Ian Osborne, concentrates much of its energies on the tech sector and is reported to have represented Napster founder and former Facebook president Sean Parker, and computer programmer Nick D'Aloisio, who rose to fame for developing and selling Summly while still in his teens.
Jones first hinted at his new position on Twitter in August.
