Two months after a mutual parting of ways with SAP, former CEO Léo Apotheker has surfaced, joining the board of GT Nexus, a trade management software vendor based in Oakland.

A 20-plus year veteran of SAP, Apotheker resigned in early February, though he was shown the door by the vendor when it declined to renew his contract. His stint at the top was short-lived: he became co-chief executive in April 2008, as the company transitioned its management from CEO Henning Kagermann, who officially stepped down in July 2009.
