Throwin' SaltThrowin' Salt sells high-end watches on eBay. Until August 2026 every listing was built by hand in InkFrog, a tool that was also shutting down. ZENIA built Gaia, an AI agent that lives in the team's WhatsApp: it prepares each listing with title, specs, photos and price, enforces the house rules and publishes on eBay when the team says «publish». This is phase 1.


Every fine-watch listing needs the same things: the exact reference with its variant, the right material and size, eight photos in the house order and a price that is not off by a zero. Doing it by hand in InkFrog took hours, and a wrong spec meant deleting the listing.
On top of that, InkFrog was shutting down. Throwin' Salt needed a faster way to list, with fewer mistakes, without changing how the team already works: on WhatsApp.
Five pieces, one conversation.
The team writes to it like a colleague: sends references or photos, asks for a price change or says «publish». Gaia answers in seconds, shows a preview of each listing and fixes it by chat. It speaks Spanish and understands voice notes.
Gaia builds each listing with an optimised title, full specs, condition, eight photos in the house order and a price, and publishes it on eBay. It also edits or ends live listings, from the same chat.
Every photo goes through a vision model before it reaches the listing: no hands or wrists, no boxes that are not the brand's, and Full Set confirmed by looking at the photos themselves. The team stopped hunting mistakes by eye.
Every morning Gaia proposes a batch of new watches, all Full Set, with the exact reference, eight photos and a calculated price, never repeating anything already listed. The team removes, corrects and publishes from the chat.
A record of every listing (who asked for it, when, at what price) and a private panel of everything listed, to follow the business and the accounts.
With listing solved, the focus moves to a wider catalogue of available references, tiered pricing and taking the same agent to Instagram and Facebook.
The same pattern works for any business with a catalogue: an agent in the team's WhatsApp that turns messages into live listings, without touching a dashboard.
In 30 minutes we show you what an agent like this would look like for your catalogue, on eBay, your website or any marketplace.
