Will delivery networks predict our orders at the limit? (The Derby Mill Series ep 31)
Could delivery networks use data from agentic AI to deliver parcels before customers know they want them?
Jun 9, 2026
UK-based Relay is a fast-growing delivery company whose mission is to lower the cost of last-mile fulfillment. CEO and co-founder Jonathan Jenssen say his team is reinventing networks for modern e-commerce. Relay covers about 23% of the UK, has a 4% share in operating postal codes and includes on its customer list such brands as Vinted, Temu, Shein, TikTok Shop, ASOS and Next.
One big challenge for Relay is that the last mile amounts to ~70% of total delivery cost. Also confounding cost decreases is the fact that the parking-to-doorstep journey amounts to ~80% of last-mile time. That all means that about half of the total cost of package delivery is in the last 100 metres of the delivery.
To decrease those costs, Jenssen’s team is harnessing the power of AI to make the last few hundred metres of the delivery more efficient. Gone are the days of hub and spoke routing and half-empty delivery trucks. Algorithms provide couriers with next-best-actions, in the form of turn-by-turn driving and parking directions, tips for building entry, and doorstep handover. They also use dynamic per-route pricing and live supply/demand matching, dynamic routing and an asset-light pit stop network of delivery depots that currently includes 10,000 local shops.
The Derby Mill team explores where Relay’s efficiency improvements may go at the limit of AI’s capabilities. Where could robots fit in? What if Relay had access to more consumer information? Could that allow the company to actually predict customer requests? And what does all this have to do with something called “the beer game,” an MIT Sloan business case? These questions and more are answered in episode 31 of The Derby Mill Series.
