About

The one that got away — found.

White Whale is an AI-powered product-discovery and monitoring tool for vintage and secondhand fashion. It exists for a specific kind of shopper: the one hunting a single, particular piece — an archival runway dress, a discontinued bag, a rare edition — that never seems to be listed when you're looking, and sells in an hour when it finally is.

Instead of refreshing a dozen marketplaces by hand, you describe the piece or upload a photo of it. Our vision model learns what it looks like and watches the resale market for you, matching listings by appearance — not just keywords — so it catches the right item even when a seller mislabels or under-describes it. When a confident match surfaces for sale, we alert you with the listing and a link to buy.

Why "White Whale"

Because everyone who loves a category has one — the piece they'll cross an ocean for. We're The White Whale Crew, and the whole product is built around helping you land yours.

Where we are

White Whale is in active development, moving toward beta. We're a small team building carefully, and we're bringing early members and founding marketplace partners aboard now, ahead of a wider launch.

Run a marketplace?

We send high-intent buyers directly to the listing they've been hunting. If you operate a resale or secondhand marketplace, see our partnership brief — or just get in touch.
