Our Leadership

Mark Probyn and John Liburti are the Founding Directors of Cherub.  Each has a management consulting and commercial background cultivated over 25 years in senior management roles in tier one consulting and commercial organisations.

John and Mark met in KPMG's Australian Sourcing Practice and moved to Gartner's Consulting Sourcing Practice, where Mark was their Global Head of Sourcing, and John, the APAC Sourcing Lead.

They continue to keep their hand in Cherub's Consulting and Solutions service arms, seeing first hand how the right services and contract can impact an organisation's front line operators and operations, as well as bottom line results.

Through Cherub, Mark and John are able to share their insights, thought leadership and experiences by presenting and advising senior client executives on pragmatic strategies on how to maximise the value of their business' IT sourcing initiatives.
