Built for eBay sellers managing inventory across channels.
Existing multi-channel tools are built for Shopify-first sellers and bolt on eBay awkwardly, leaving eBay-native sellers perpetually underserved

Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
Individual eBay sellers managing multi-channel inventory face inventory sync friction. Zero monthly searches indicates this is a pain point driven by word-of-mouth, not search volume.
Competition & the opening
Few direct competitors exist; eBay's official integrations and generic inventory tools like TradeGecko or Linnworks serve this segment weakly. The gap is tight, eBay-specific sync without monthly fees.

What's hard to build
eBay's API is rate-limited and requires seller authentication; real-time sync across channels introduces consistency and conflict-resolution logic. Data staleness and partial sync failures are hard to handle gracefully.
Why now
eBay's official sync tools are clunky; multi-channel sellers have no unified inventory layer.
