Zellerfeld, the German 3D-printed footwear manufacturer, is bolstering its leadership team as it continues to expand globally. On Thursday, the company named Matthew DeNezza as chief financial officer and Sean McCartney as chief operating officer. DeNezza and McCartney will work closely with co-founder and chief executive officer Cornelius Schmitt to “align financial discipline with operational execution,” Zellerfeld said. “Matt and Sean each bring critical experience as Zellerfeld enters its next phase of growth,” Schmitt said in a statement. The move aims to reinforce the company’s commitment to reshoring manufacturing and building a fully automated, waste-free production model designed for on-demand, localized production, Zellerfeld said.
