Troostwijk Auctions expands cross-publishing with auction brand Surplex

Amsterdam, 26 June 2025 - Troostwijk Auctions, leading European online auction platform for B2B used industrial equipment and part of the TBAuctions (TBA) network, is taking the next step in strengthening its selling power. Following a successful test with Belgian sister brand Vavato, cross-publishing is now being rolled out further in collaboration with German sister brand Surplex, which operates across Continental Europe. By significantly increasing the visibility of lots, cross-publishing enhances opportunities for sellers and improves the auction experience for buyers across the TBA ecosystem. 

One auction, many storefronts
Cross-publishing allows a lot originally listed on one TBA brand platform to appear in additional storefronts, enabling bidders from different brands to view, follow, and bid in real-time. This is how this innovation breaks down brand silos to create a seamless bidding experience. While the sourcing platform retains ownership of the lot and handles the transaction, the additional storefronts act as extended channels, amplifying reach and engagement. Maximum visibility and seamless bidding.

Higher engagement and strong results
Internal data from March 2025 revealed that 20% of lots on Vavato and Troostwijk Auctions were cross-published, with especially strong results when items moved from smaller to larger platforms. Lots cross-published from Vavato to Troostwijk, for instance, saw higher engagement and significantly fewer instances of unsold lots.   

Driving Platform Synergy Through Network Effects 
By activating bidder bases across multiple storefronts, the TBA ecosystem strengthens its marketplace dynamics. Cross-published lots are shown to more potential bidders, increasing the odds of sale and driving competition—leading to higher conversion rates.  

“Cross-publishing embodies our platform’s digital potential,” said Robbie Strickland, Chief Technology and Product Officer at TBAuctions. “It’s a powerful, scalable feature that brings together previously independent bidder pools, delivering more eyes on each lot and unlocking measurable value for both buyers and sellers. It’s an elegant example of how we are transforming auctions with data and technology.” 

A Unified Multi-Brand Experience
For sellers, cross-publishing means maximum exposure without added complexity. For bidders, it offers a more comprehensive view of available lots across the TBA ecosystem—regardless of which storefront they visit. 

“This is a pivotal step toward realizing our vision of a unified auction ecosystem,” added Strickland. “Cross-publishing helps buyers discover more relevant items while empowering sellers with greater reach. It reinforces our commitment to building a seamless digital platform that creates scale, trust, and opportunity for all users.”
