Build a Resale Sourcing Intelligence Scout

1. 1

   Source data within the rules

   Work from the auction platforms' public listings, estate sale companies' published feeds, and marketplace data accessed within each site's terms. Getting users banned or getting sued over scraped data ends the business; where clean APIs and feeds exist, pay for them, and skip the sources that forbid you.

2. 2

   Build the photo intelligence loop

   Detect resale-relevant categories in listing photos, tools, instruments, electronics, vintage goods, and score lots and sales on likely value density with clear confidence labels. Let users correct scores after visits; that feedback trains a scout that gets sharper than any competitor starting fresh.

3. 3

   Make alerts arrive when speed matters

   Estate sale finds and underpriced marketplace listings are won in the first minutes. Instant push alerts filtered by category, radius, and score threshold, with the key photos inline, decide whether your tool prints money or reports history.

4. 4

   Ship reverse-image target lists

   Let resellers save visual targets, a specific camera model, a sneaker silhouette, a furniture style, and get alerts when a matching listing appears locally below their price threshold. This saved-hunt mechanic is the feature users describe to friends, which is your growth loop.

5. 5

   Respect the honesty rules of the trade

   Value scores are probabilistic, storage units are sold as-is, and no algorithm sees inside boxes; say so plainly. Overpromising leads users into bad bids they blame you for, and this community's forums have long memories.

6. 6

   Price against one good flip

   A subscription in the range of $25 to $60 a month is trivial next to a single storage unit or estate score. Reseller YouTube and podcast sponsorships reach exactly this audience, and creators will happily test the scout on camera.
