Jane Street Asia uses Excel-DNA.

“We migrated to ExcelDNA, which has simplified greatly our Excel interfacing. It is a superb product, superior to others we have used previously, and Govert is incredibly responsive and helpful in maintaining and improving it.” – Alberto Cherubini, EQ Finance
“ExcelDNA is in use in our major locations around the world and in many mission critical scenarios. Usage covers the full gamut of features from simple UDF add-ins to managing real-time trading flow, interacting with order management systems. The open source ExcelDNA project is incredibly useful to us. Thanks very much to Govert and contributors.” – Paul Gresham, Hong Kong.
