What WSI (Warehouse Specialists) does

WSI (Warehouse Specialists, LLC) is a privately held U.S. third-party logistics provider founded in 1966 and headquartered in Appleton, Wisconsin. The company operates 20+ owned and operated facilities spanning more than 13 million square feet across 10 states, offering contract warehousing, omnichannel fulfillment, and transportation services (parcel, LTL/FTL, drayage) to manufacturers, retailers, and consumer brands. WSI is differentiated by deep regulatory expertise in chemical and hazardous-materials logistics, holding Responsible Care Partner of the Year (2025 and 2026), Operation Clean Sweep Logistics Certification, and EcoVadis Silver (top 15% globally), with primary verticals spanning chemicals, plastics & polymers, pulp & paper, food & beverage, and retail / ecommerce.

The technology stack is a conventional 3PL systems layer rather than an AI-native platform: Warehouse Management System (WMS), Order Management System (OMS), Transportation Management System (TMS), and a Labor Management System (LMS), supplemented by real-time dashboards, predictive analytics for demand forecasting, scenario modeling, and ecommerce / marketplace integrations. There is no publicly documented API, SDK, or proprietary model. Underlying the core operation are two retained acquired brands — Pac-Modal (drayage, brokerage, trucking, acquired Nov 2023) and Kase (cloud-based ecommerce fulfillment, acquired 2024 and relaunched as a distinct omnichannel 3PL sub-brand in March 2025) — alongside the WSI Freight Solutions brokerage unit.

WSI's business model combines recurring contract warehousing revenue (long-term, multi-year agreements for dedicated, multi-tenant, or hybrid space, including chemical, food-grade, and rail-served facilities) with transaction-based fulfillment and transportation fees (pick/pack, parcel, LTL/FTL, drayage) and project-based value-added services such as chemical blending, repackaging, and tank farm management. Pricing is custom-quoted per engagement with no published rates, and the go-to-market is enterprise field sales targeting supply chain and operations leaders, with a dedicated mid-market / DTC channel via the Kase brand. Leadership includes CEO Bob Schroeder, President Paul Simmons (formerly COO), CFO Daniel VandenHeuvel, and President of Pac-Modal Jackson Fuiten; the company remains privately owned with no disclosed institutional investors.
