Marleen Vogelaar

Marleen Vogelaar is a Dutch entrepreneur who co-founded Shapeways in 2007, helped build it into the world's largest 3D printing marketplace, left in 2014 to start the on-demand apparel company Ziel, and then returned to Shapeways as CEO in December 2024 after the company went bankrupt - buying back the brand and rebuilding it around a leaner, B2B, profit-first model. A former competitive heptathlete and industrial engineer, she is known for pairing operational discipline with an insistence that a company's mission should not be hostage to its investors, an idea she put into practice by converting Ziel to steward-ownership.
