Soapbox

Soapbox is a unified supply chain platform that brings order management, inventory management, and shipping management together in one connected system. Originally built on the warehouse floor to run the founders' own warehouse and 4PL network, Soapbox was designed from the ground up as a single platform rather than a collection of tools stitched together after the fact. The platform serves operations teams at consumer brands, CPG companies, retailers, and 3PLs managing anywhere from 1,000 to over 100,000 orders per month, with customers ranging from $3M DTC brands to Fortune 100 enterprises across retail, CPG, and healthcare verticals.

The platform solves the fragmentation problem that plagues supply chain operations: the costly, error-prone reality of managing orders, inventory, fulfillment, and shipping across disconnected tools. Soapbox replaces the patchwork of ERPs, spreadsheets, carrier portals, and warehouse systems with a single connected layer where data stays aligned automatically. Key capabilities include automated order routing based on live inventory and warehouse availability, real-time inventory synchronization across warehouses and 3PLs, carrier optimization with discounted parcel and LTL freight rate shopping, and an embedded EDI layer powered by SPS Commerce and CartRover that supports 500+ trading partners and 23 document types. The platform claims to reduce retailer chargebacks by 50-80% and deliver a 5x ROI.

Soapbox integrates with a broad ecosystem of commerce channels, carriers, ERPs, and fulfillment partners, and provides production-ready REST APIs for custom development. The company, founded in 2019 in Los Angeles, has raised a seed round backed by Mucker, Mantis, Switch, Aglae, and S&A Family Office. It has managed over 2 million orders and reports a 25% reduction in inventory losses for customers. Its sister operation, Basic 3PL, offers enterprise-grade fulfillment services running on the Soapbox platform with no minimums and rapid go-live timelines.
