bartir

Product Thesis

Most collector platforms (e.g. StockX, Depop) are shipping-first and charge 8–13% in fees. bartir bets on the unoccupied corner: local, fee-free, community-driven trading.

UX built around niche communities (e.g. vinyl in NYC) solves the cold-start problem that killed every general barter app before it.

A shelf-driven home feed and a fully filterable catalog surface what’s available to the user within walking distance. bartir’s distance chips and an approximate-location map that never reveals an exact address.

The trade flow

A structured six-step listing flow with per-category attribute schemas allows us to capture the most important information about each product, regardless of what it is.

A full trade lifecycle (propose, counter, accept, complete) with direct messaging scoped to each trade.

Trust & privacy

Trust is the product. Profiles carry trading stats and community membership.

Locations are shown as approximate circles, never coordinates, and access was gated and staged to satisfy safety requirements.

Brand & go-to-market

A custom wordmark with a built-in swap glyph, a green-forward identity, and an automated pipeline that renders branded ad creatives at every social size.

The same design system runs from the app straight into a full funnel of campaign assets.

Under the hood

A type-safe, two-client product built solo: one schema flowing from database to API to both apps with zero hand-written duplication.
