The WSI story
From one warehouse to one of the nation’s largest 3PLs
WSI was founded in 1966 by six entrepreneurs who poured the foundation—literally—of our first warehouse in Wisconsin. What started with a hands-on mindset and a single building has grown into one of the largest privately held logistics companies in North America.
That same roll-up-your-sleeves spirit continues to drive us today, as we support customers across industries with reliable, scalable supply chain solutions.
WSI & Kase: Strong together
WSI and Kase share a common vision and values, centered around customer satisfaction, operational excellence, and community involvement. As affiliated companies, Kase operates as WSI’s tech-forward fulfillment arm, leveraging 60 years of supply chain expertise to deliver innovative solutions and exceptional customer experiences.
