Whaler — know your whales
A buyer CRM for Whatnot live-auction sellers that identifies high-spending customers, tracks their purchase history, and flags buyers who may be drifting away.
Field notes
Whaler describes a browser-extension workflow that runs alongside a seller's Whatnot show rather than requiring a separate operating dashboard. Auction wins are attributed to individual buyers, then accumulated into cross-show profiles with spending history, whale status, and indicators for declining activity. The page displays 8 sellers tracked, 372 buyers profiled, 1.2k purchases logged, and 21 whales found. Its $25 monthly Seller plan includes live alerts, buyer segments, win-back lists, and revenue-concentration reporting.
