Loop

Loop is a full-stack, AI-powered logistics data platform that unifies the fragmented operational and financial data of the physical economy. Founded by former Uber Freight leaders Matt McKinney and Shaosu Liu, Loop began in freight audit and payment and has expanded into an intelligence layer spanning freight audit, parcel and carrier-invoice auditing, real-time shipment visibility, parcel contract optimization, carrier payments, and autonomous exception management (DUX and the Exception Agent). The Loop developer platform exposes a REST API (api.loop.com/v1) for ingesting artifacts (invoices, shipment records, purchase orders), resolving business exceptions, managing organizations and factoring/invoicing relationships, and reading payable/receivable invoices and payments, plus a separate Onboarding API and Svix-based webhooks. Loop has raised $210M total, including a $95M Series C, from Valor Equity Partners, 8VC, Founders Fund, Index Ventures, J.P. Morgan Growth Equity, and others.

Loop publishes 14 APIs on the APIs.io network, including artifacts API, artifacts-schema-validated API, business-exceptions API, and 11 more. Tagged areas include Company, Logistics, Supply Chain, Freight, and Freight Audit.

The Loop catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Loop’s developer surface includes authentication, documentation, API reference, getting-started guide, engineering blog, signup flow, and 20 more developer resources.
