Rex

Rex is an AI-native service for order to cash. We replace people-heavy operations with AI agents that continuously manage invoices, customers and exceptions. Order to cash is a $60B outsourced function because the work is too messy for traditional automation. Every customer has different context, exceptions do not follow clean rules, and the next step is often buried in emails, portals, handoffs, or someone’s memory. Rex agents run continuously in the background and resolve work to SLA standards

Handled

Post-order operations are one of the least automated parts of e-commerce. After an order is placed, teams still spend their days tracking shipments, chasing exceptions, processing returns, adjusting invoices, and answering “Can you check this?” requests. This manual busywork lives outside core systems and scales linearly with order volume, forcing brands and 3PLs to keep adding headcount as they scale. Handled is an operations automation platform for e-commerce brands and the 3PLs that run their
