GBST Adds Coexis’ Williams to Exec Team as Chairman of European Ops

Subscribe to our newsletter

Following the completion of its acquisition of Coexis last year, Australian securities services technology vendor GBST has appointed Coexis’ executive chairman, Terry Williams, to its executive team as chairman of its European operations. He will also act as an advisor to the board of directors and will focus on growing the vendor’s operations in the UK and internationally.

The vendor hopes that its acquisition of Coexis will allow it access to the European marketplace, which GBST founder and chair, John Puttick, describes as “important and evolving”. In December, the vendor announced that both Williams and Sunil Shah, previously CEO of Coexis, would join the GBST executive team. However, Williams’ appointment on the operations side of the European business is part of the drive to get traction in this region via his contacts and experience.

Williams worked for Coexis for a period of six, during which he was CEO and, later, executive chairman. He led the team that deployed the company‘s flagship software, Syn~, at investment banks and brokers across Europe, the US and Asia-Pacific

Prior to joining Coexis, Williams led ADP Wilco, a subsidiary of global business outsourcing giant Automatic Data Processing. Williams founded Wilco, which was bought by ADP (now Broadridge) in 1996.
