Whale tracking · built for Whatnot card breakers

Know which buyers
actually move your breaks.

In every break, a handful of buyers drive most of the money. Whaler tracks every auction win from your own show, flags a whale the second they join, and shows exactly what they chase — so you take care of the right buyers in the moment.

The problem

Your biggest buyer just joined. Did you notice?

Mid-break, the chat is flying and you're calling lots. The buyer who's dropped four figures on your Prizm cases slides into the room and you have no idea — no shout-out, no hold, no reason for them to stay. Multiply that across every show and it's the quietest way a breaker leaves money on the table.

What Whaler does

A real whale list, from your real sales.

Spot every whale, instantly
The moment a buyer joins your break, Whaler shows who they are and everything they've spent across all your shows — so no high-roller walks in unnoticed.
See what they chase
Whaler reads your break titles and sets, so a whale isn't just a big number — it's the buyer who hunts numbered rookies, case hits, or a specific set. You know what to put in front of them.
Win them back before they cool
When a regular whale starts to go quiet, Whaler flags them with what they love to buy and drafts the message — one tap to pull them back before they're gone.
Why the data matters

Your ledger, not an estimate.

Whaler captures every win straight from your own Whatnot seller console — the exact buyer and the exact price. When you're deciding who to comp, hold a lot for, or win back, you want the real number, not a guess pieced together from what the room happened to show. That accuracy is the whole point of a whale list.

Common questions

Whatnot whale tracking, answered.

What counts as a whale on Whatnot?
In every break, a small group of buyers drives most of the money. Whaler ranks each buyer by their real spend with you and marks the top group past a floor as your whales — so “whale” means a genuine high-roller, not just someone who bought once on a hot night.
How does Whaler know who my whales are?
It captures every auction win from your own Whatnot seller show and attributes it to the buyer. Your whale list is built from your actual sales ledger — exact buyer, exact price, every lot — not estimated from the public feed.
Does it work across all my shows?
Yes. A buyer’s spend and whale status build across every show you run, so a whale who walks into tonight’s break is recognized even if you’ve never personally sold to them on this shift.
How much does it cost?
Whale names and live alerts are included from the base plan at $25/mo — priced for a working breaker, not a brand team.
