Dunzo was late to commit fully to the dark store model that competitors like Blinkit and Zepto pursued aggressively from 2021. This delay allowed competitors to build dark store density in key markets while Dunzo was still operating a hybrid model, resulting in speed and availability disadvantages that accelerated consumer switching.

Dunzo's financial planning was built on assumptions about the pace and magnitude of Reliance's operational support that proved overly optimistic. The expectation that Reliance's supply chain integration would materially improve unit economics within 12 to 18 months of the investment was not realized, leaving Dunzo in a capital gap it could not bridge.

Dunzo prioritized city count and order volume growth over resolving fundamental unit economics challenges, scaling negative contribution margin operations across six cities rather than demonstrating profitability in one market before expanding. This approach consumed capital without building the operational proof points needed to attract follow-on funding in a tighter investment climate.

The company's inability to maintain salary payment reliability during 2022 and 2023 triggered an accelerating talent exodus at senior and mid-levels that was extremely difficult to reverse. The loss of key engineering, product, and operations leaders compounded every other operational challenge and reduced the company's ability to execute its recovery strategy.

Expanding to six Indian metros before achieving sustainable unit economics in Bangalore created a sprawling operational footprint that was expensive to maintain and difficult to manage. A more disciplined approach of mastering one or two markets before expanding might have preserved capital for the competitive battles that ultimately determined the outcome.
