Whatnot needed to find TCG sellers in the UK, Netherlands, and France who could anchor live auction streams. Not just any sellers, but ones with established audiences, consistent inventory, and proven selling ability.
Many doubted such sellers existed in these markets at scale. The assumption was that international TCG commerce happened primarily through local shops and traditional marketplaces, not social media. Finding social media creators who were also serious card sellers seemed unlikely, especially outside major cities.
Sixtyfour proved the sellers existed. The platform identified social media accounts across Europe that showed Pokemon, Magic, and other TCG content, then recursively researched each one to determine commercial viability.
From a single seller handle, Sixtyfour's agents would uncover the complete seller profile: their eBay store showing monthly transaction volume, their TILT link revealing all selling channels, their Instagram with business contact information, their participation in card grading services. The agents distinguished between casual collectors making content and serious sellers moving real volume.
This recursive research transformed sparse social media presence into actionable intelligence. A Dutch social media account with 3,000 followers might turn out to be moving €10,000 monthly in graded Pokemon cards. A French creator doing pack openings might have a warehouse full of vintage inventory. These sellers existed, but only comprehensive research could identify them.
Whatnot's AEs used Sixtyfour's agents to generate pre-qualified lists with complete profiles: verified sales history, inventory depth, audience metrics, and direct contact information. Every account found was exactly who Whatnot needed to bring to the platform.
Sixtyfour identified hundreds of qualified TCG sellers across European social media that no one believed existed at this scale. The platform found serious card sellers in Netherlands suburbs, vintage Pokemon dealers in French cities, and Magic the Gathering specialists throughout the UK, all with existing social audiences ready for live commerce.
What seemed impossible to find manually, Sixtyfour delivered systematically. Whatnot could enter European markets knowing exactly which sellers to recruit, with all the context needed to close them.
