JOKR Claims Double Grocery Profitability
Ralf Wenzel, founder and CEO of JOKR, on the biggest misconceptions in ultrafast delivery
The core bet is that dark stores can turn grocery from a low margin weekly stock up into a denser, more software driven convenience business. JOKR argues margins improve because the same operator controls inventory, picking, delivery, and marketing, and can tune assortment by neighborhood and time of day. That matters because offline grocers usually earn only low single digit EBITDA margins, while mature ultrafast stores were projected to reach about 13% contribution margin before full fixed costs.

The path to higher profitability is narrower than a normal supermarket. Ultrafast dark stores usually carry roughly 1,000 to 2,000 SKUs from spaces around 3,000 square feet, versus about 30,000 SKUs in a supermarket. That smaller box cuts waste and speeds picking, but it pushes the model toward high frequency convenience baskets, not full basket grocery.

This is also why the closest comparison is not Instacart. Instacart is a marketplace that sends shoppers into partner stores and makes money from fees, ads, and retailer software, while JOKR and Gopuff own inventory in local dark stores and capture the full retail margin. The upside is more control. The burden is paying for spoilage, labor, and inventory directly.

The operational proof point in the interview is store maturity. JOKR targets per store profitability in about 18 months, and ties margin expansion to repeat behavior, higher basket size, and direct procurement. In the broader category, mature dark stores were modeled at 500 orders per day and about $25 average order value to reach healthy contribution economics.
Going forward, the winners in ultrafast delivery are likely to look less like digital supermarkets and more like app first convenience chains. The strongest operators will use dense neighborhood demand, direct supplier relationships, and sharper product mix to push beyond grocery economics. If that works, the category expands from emergency snacks into a broader everyday retail habit.
