As the founder and chairman of Danube Group, one of the emirate’s most successful business conglomerates, Rizwan Sajan has supplied building materials to just about every development since the property boom began. The company is now the undisputed market leader in building materials in the emirate, created through years of astute growth under Sajan’s leadership. Danube Group also is evidence that Dubai’s property market is back: “The business doubled in the past year,” Sajan told us in September. He should know; in the last 12 months, his company has launched two new property projects in the emirate.
