Walmart Seller Experience

4.8-rated Seller Mobile, 50%+ adoption
MarketplaceAI/MLMobile1 → 10
Context

Walmart’s third-party marketplace was scaling, and the experience that determined whether a seller thrived or churned lived in fragmented desktop tooling. I owned the seller experience — the mobile app and the Action Feed that became its spine.

The Problem

Walmart’s growing third-party marketplace had sellers running their business on desktop tools that didn’t fit how they actually worked — on the floor, on a phone, between tasks.

Approach

Sellers don’t live at a desk. The product had to meet them where the work happens.

Designed the Action Feed architecture — a prioritized, opinionated stream that told a seller the single most valuable thing to do next, rather than a dashboard of everything.

Built Seller Mobile as a first-class surface, not a shrunk-down web port — the interactions matched how sellers actually triage between other tasks.

Used activation and retention as the north star instead of feature count, which kept the roadmap honest about what sellers returned for.

Outcomes
4.8
Seller Mobile app rating (iOS + Android combined)
A tools product — not a consumer app — earning a consumer-grade rating.
50%+
Adoption across the Walmart marketplace seller base
Crossed from “nice to have” to default channel for managing a seller business.
~70%
Seller Forums activation in month one
The Action Feed turned a static dashboard into a place sellers came back to daily.
What I learned

A tools product earns a 4.8 the same way a consumer app does: by respecting the user’s time. The Action Feed worked because it made a decision for the seller — here is the one thing worth doing now — instead of offloading prioritization onto them. The lesson that generalized: in operator tooling, opinionated beats comprehensive.
