HRH Prince Constantijn visited Sioux together with StartupDelta, as part of a Brainport tour. The company got a demonstration of the digital PCB printer MuTracx built. One of the numerous start-ups that Sioux is intensively involved in.

The prince praised Sioux's investments in promising start-ups: 'It is good to see that such a company as Sioux is investing in start-ups and that it offers them space and a network of customers. Many large companies still do too little, while it greatly increases the success rate of start-ups.'
