Dark store economics force consolidation

This is a market where weak unit economics force consolidation early. Grocery delivery adds picking, packing, spoilage, and last mile costs on top of thin grocery margins, so scale alone does not save everyone. The operators that survive are the ones that either build dense dark store networks with enough order volume and basket size, or use an existing marketplace and customer base to spread delivery costs across more demand.

• Dark stores only work if basket size gets high enough. In the online grocery model, moving AOV from £10 to £25 to £50 sharply improves contribution margin because labor and delivery stay roughly fixed per order, which is why small convenience baskets support fewer viable players.

• Marketplace players like Deliveroo have demand and courier supply, but the point to point model is less suited to large grocery baskets. Internal research estimated roughly 2 drops per hour for Deliveroo versus 6 for Getir, and the interview notes motorbike couriers are a poor fit for £100 to £200 weekly shops.

• The ride hailing comparison is really about industry structure. In marketplaces with on demand delivery, the category tends to settle into a duopoly because demand concentration and local scale matter. A separate interview on the same market expected six or seven UK players to narrow to two or three after the funding rush.

The end state is likely a smaller set of city by city winners, plus incumbents using stores, supplier relationships, and customer traffic to absorb demand. The companies that endure will look less like full grocery stores on demand, and more like tightly run convenience networks that push higher margin mixes and larger, denser baskets.
