Field composites
Aarav 34 years · Dark-store ops manager · dense-urban metro
Runs a cluster of three dark stores within a 2 km radius of BKC, each serving 1,200–1,400 orders per day. The math on paper, modelled from listed-aggregator segment disclosures, is AOV ₹520, take-rate 19%, contribution margin 4.2% on the mature-cohort customer base. Density is the moat. At <0.4 dark-stores per sq.km, fulfillment cost ratchets up disproportionately; above 0.6 per sq.km, the rider-utilisation curve flattens and contribution stabilises.
Aarav's three stores share rider fleets through a city-wide pool. The composite-modelled friction is not at the order — it is at the night-shift gap, when the rider-batching algorithm thins out and per-order fulfillment cost spikes 30–40%. The publicly-disclosed segment contribution-margin number — quarterly, blended — averages this out. The night-shift cohort sits inside that average, structurally invisible.

Tasked with opening 18 dark stores in Pune over 9 months. The funding round was raised on a thesis of replicating metro economics at Tier-2 AOV. The composite-modelled friction is the gap between the metro AOV envelope (₹520) and the Pune AOV envelope (₹340 — closer to ₹290 in the suburban cohorts).
Fulfillment cost does not scale down proportionally — a 1.8 km median ride still takes a rider 7–9 minutes regardless of basket size. At AOV ₹290 and ₹85 fulfillment cost, the contribution-margin envelope inverts before take-rate is even applied. Cohort-cohort retention at month-12 holds the deal together or falls below the payback threshold. The dark-store-ROI deck the round was raised on does not survive this cohort math.
Meera 39 years · Restructuring lead · QC segment review
Reviews the dark-store portfolio post a Q4 earnings call in which the board asked for a sharper EBITDA path. Three structural items from the modelled scenario surface the operational gap between the announcement-grade portfolio and the contribution-grade reality:
- Total dark stores: ~430. Density-mature stores (metro core, >0.6 per sq.km): ~210. Density-immature stores (Tier-2 ramps + suburban metro fringes): ~190. The remaining cluster sits in a contribution-margin grey zone the segment-disclosure does not break out.
- Average dark-store payback: 22–28 months at metro density · 38–52 months at Tier-2 ramp · indefinite below ₹300 AOV cohort. The 22-month payback drove the segment expansion thesis. The 38–52 month payback would not have.
- Customer-cashback subsidy: a structural component of order flow at Tier-2, blended into the marketing line. Removing the subsidy materially compresses orders before unit economics improve. The path from "subsidy-led growth" to "organic-margin path" is what the board call is really asking about.
