Timothy Nordin brings nearly two decades of experience in transforming finance, procurement, and supply chain operations.
Tim's career and experience was aptly timed with the disruption of the spend management space and the rise of cloud technology. Tim led several of the earliest projects in North America, allowing companies to drive bottom-line savings, reduce risk, and unlock working capital in projects that were completed in months instead of years.
With the rest of the Optis team, Tim is responsible for operations, sales, and delivery across a portfolio of global clients. Tim splits his time between his home in New York and Optis' newest office in London.
