Story
Goal
Build the fastest, most reliable grocery marketplace in the country—able to:
- Guarantee delivery windows as tight as 20 minutes for urban cores.
- Auto‑substitute out‑of‑stock items with >90 % shopper acceptance.
- Lift average basket size while protecting razor‑thin grocery margins.
- Scale seamlessly from 4 M to 10 M monthly orders without service degradation.
Challenge
Even with booming demand, the legacy stack strained under volume and complexity:
- Inventory Blind Spots — store‑level stock updated every 30 min, driving cancellations.
- Inefficient Routing — static batch dispatch added 11 min to every drop.
- Substitution Rage — random replacements tanked CSAT to 63 %.
- Basket Abandonment — shipping fees & delivery uncertainty killed 22 % of carts.
- Dark‑Store Silos — data fragmentation across micro‑fulfillment hubs.
- Regulatory Maze — alcohol, age‑gated goods, and regional surcharges.
These frictions threatened growth in a market hurtling toward $640 B globally. wavegrocery.com
Our Approach
Discover
Shadowed 60 shoppers + 45 couriers; latency heat‑maps pinpointed every >300 ms slowdown.

Challange
The Mountain to Climb
These frictions threatened growth in a highly competitive space:
Inventory Blind Spots
4.8 % of SKUs showed phantom stock—leading to last‑minute cancellations.
Routing Lag
Drivers averaged 2.1 km of dead‑heading per order.
Substitution Rage
CSAT dipped below grocery benchmark 70 % when items were swapped randomly.
Basket Abandonment
Delivery‑fee shock above $7 stalled growth and killed 22 % of potential checkouts.
Data Silos
5 separate systems across dark‑store, in‑store & partner POS led to fragmentation.
Compliance Pressure
Alcohol checks averaged 90 s curbside, adding friction to the final step.
Additional Hurdles
Narrow freezer capacity complicated order stacking and wave picking.
Surge‑pricing backlash from customers—perceived as “gouging.”
Rising fuel costs squeezed margins further, requiring real‑time route optimization.
Addressing these challenges demanded a holistic solution—data, tech, and operational synergy.
