Topsort announced the launch of T-Brain.

Topsort announced the launch of T-Brain. Search. Built on intelligence developed through billions of commerce decisions, T-Brain brings commerce-specific AI to the systems that power modern commerce. Today at Topsort Fall Update 2026, Topsort introduced T-Brain, the company's first Large Commerce Model (LCM). A commerce-specific foundation model, Theo is designed to understand signals from products, catalogs, queries, shoppers and transactions - and apply that intelligence across multiple commerce decisions. T-Brain supports use cases spanning search, retrieval, ranking, recommendations, advertising and agentic commerce experiences. It is designed to adapt to each enterprise's catalog, shopper behavior and commerce environment, providing a shared intelligence foundation for decisions across commerce systems. T-Brain builds on intelligence developed as Topsort powered billions of commerce decisions across more than 100 marketplaces. Topsort first applied machine learning to a central commerce decision: which sponsored product to show, balancing shopper relevance, advertiser performance and marketplace revenue. T-Brain extends that work beyond advertising to a broader set of commerce decisions. "AI has changed the technology landscape quickly, and commerce is entering a period of significant change as well," said Regina Ye, CEO and Co-founder of Topsort. "I expect the online store to look fundamentally different in the next 12 to 18 months. As AI reshapes commerce category by category, businesses will need more than another assistant added to existing software. They will need intelligence that understands how their business works and helps their systems make better decisions. T-Brain is our foundation for building toward that future." "We've been working on this for two years. Large language models are built to understand and generate language; a Large Commerce Model learns the relationships among products, shoppers, intent and outcomes to help predict what a shopper is likely to do next," said Francisco Larrain, Co-founder and CTO of Topsort. "With T-Brain, we're bringing that commerce-specific intelligence into a shared model foundation that can support search, retrieval, ranking, advertising and agentic experiences." In early production deployments with some Topsort customers, preliminary results show a 21% improvement in retrieval and a 26% improvement in conversion on the commerce surfaces where T-Brain has been applied. Topsort is also demonstrating T-Brain at Fall Update 2026. T-Brain is in production with select existing customers. The company is demonstrating the model at Topsort Fall Update 2026 in Boston.

Topsort expands beyond retail media with enterprise Commerce AI.

Topsort expands beyond retail media with enterprise Commerce AI. Tuesday, 22 September 2026 09:00 AM Company Update. Topsort is building AI-native technology to bring intelligence across monetization, discovery, and the decisions that power modern commerce PALO ALTO, CA / ACCESS Newswire / September 22, 2026 / Topsort, the AI-native monetization infrastructure company for modern commerce, today announced its next evolution from commerce media toward a broader vision for Commerce AI. Topsort began by applying machine learning to one of commerce's most important decisions: determining what sponsored product to show, balancing relevance, advertiser performance, and retailer revenue across billions of auctions. But advertising represents only one part of how a commerce business operates. Search, recommendations, forecasting, pricing, merchandising, and monetization are still largely powered by separate systems, each making decisions with only part of the picture. AI creates an opportunity to change that by connecting intelligence across commerce rather than adding another AI feature to each individual system. "Commerce media was our starting point, but the opportunity is much bigger," said Regina Ye, CEO and Co-founder of Topsort. "The intelligence we built to understand products, shoppers, demand, and relevance can extend far beyond advertising. We believe the next generation of commerce will be AI-native at its core, and that's what Topsort is building toward." From Commerce Media to Commerce AI Topsort's evolution builds on its experience powering billions of commerce decisions across more than 100 marketplaces. The company is now extending that foundation toward a broader intelligence layer that can support decisions across discovery, ranking, personalization, forecasting, optimization, and monetization. Rather than operating as disconnected systems, these decisions can be informed by a shared understanding of the business-its products, shoppers, demand, and goals. This marks Topsort's next chapter: from powering commerce media to building the intelligence infrastructure behind commerce itself. The vision will continue at Topsort Fall Update 2026, taking place September 29-October 1, 2026, in Boston, under the theme "Commerce, Evolved." Customers, partners, industry leaders, and members of the media can register at the Topsort Fall Update 2026 event page. About Topsort Topsort is the AI-native monetization infrastructure company for modern commerce. Topsort helps retailers, marketplaces, delivery platforms and other commerce businesses build and operate monetization programs, from auction-based advertising to AI-driven decisioning across every commerce surface. Today, Topsort provides monetization infrastructure to leading enterprises across more than 40 countries, including Coles, JET, Avolta, and Falabella.

Topsort expands commerce media beyond owned surfaces with Universal Ads.

Topsort expands commerce media beyond owned surfaces with Universal Ads. Sep 16, 2026, 09:00 ET New Offsite channel enables retailers and marketplaces to extend advertiser campaigns across CTV, streaming, and digital inventory PALO ALTO, Calif., Sept. 16, 2026 /PRNewswire-PRWeb/ - Topsort, an AI-native monetization infrastructure company for modern commerce, today announced Universal Ads as a new Offsite channel, enabling retailers and marketplaces to extend their advertiser programs across CTV, streaming, and digital inventory, including inventory from major publishers such as NBCUniversal, Paramount, and Warner Bros. Commerce media is expanding across more channels and formats as consumer attention moves across search, social, streaming, AI, and other digital experiences. For retailers and marketplaces, the opportunity is to bring the advertiser demand they have already built into more of those environments. With Universal Ads, retailers and marketplaces can extend their existing advertiser demand into premium video inventory using the same Topsort Offsite workflow. Advertisers simply select Video and Universal Ads, upload a video of up to 60 seconds, set their budget and bidding strategy, and launch. Because campaigns are video-based rather than product-based, no catalog synchronization is required. "The boundaries of commerce media are disappearing," said Regina Ye, CEO of Topsort. "What used to be separate channels, formats, and advertising systems are becoming one connected monetization layer. The future isn't about adding another place to run an ad. It's about giving commerce businesses the intelligence and infrastructure to activate demand wherever opportunity exists." From Retail Media to Commerce Everywhere Universal Ads expands Topsort's Offsite capabilities into premium video inventory across North America and Europe, including reach across up to 90% of U.S. households, helping marketplaces and vendors extend campaigns beyond the marketplace at significant scale. For CTV, where viewers cannot click ads displayed on television screens, campaign performance is measured using view-through attribution rather than click-through attribution. The launch reflects a broader evolution in commerce media: as advertiser programs expand across more channels and formats, the infrastructure behind them needs to evolve with them. Topsort is building connected infrastructure to help retailers and marketplaces activate demand across more environments from one place. Universal Ads is now available as an Offsite channel through Topsort. About Topsort Topsort is the AI-native monetization infrastructure company for modern commerce. Topsort helps retailers, marketplaces, delivery platforms and other commerce businesses build and operate monetization programs, from auction-based advertising to AI-driven decisioning across every commerce surface.

Topsort partners with CDON to power marketplace-native Retail Media across the Nordics.

Topsort partners with CDON to power marketplace-native Retail Media across the Nordics. September 3, 2026 September 2, 2026 Topsort, an AI-native retail media infrastructure company, announced a partnership with CDON Group, one of the largest online marketplaces in the Nordics, to power marketplace-native retail media across its ecommerce ecosystem, reflecting a broader shift toward commerce media systems built around shopping experiences, where monetization and relevance work together in real time. Traditional retail media systems were not originally designed for the operational realities of marketplace commerce. Marketplaces involve dynamic seller ecosystems, constantly evolving catalogs, and monetization strategies that must remain tightly connected to product discovery and the customer shopping experience. As more marketplaces reconsider the complexity and limitations of legacy advertising technology, CDON Group chose a different path: adopting a modern, API-first infrastructure purpose-built for marketplace commerce media. The partnership enables CDON Group to deploy scalable sponsored product advertising while maintaining flexibility, speed, and native integration across its marketplace environment. Rather than layering monetization onto legacy ad systems not designed for marketplaces, CDON prioritized infrastructure that could adapt to the operational realities of modern marketplace commerce. "From the beginning, we knew we didn't want to build retail media on top of legacy ad tech that wasn't designed for marketplaces," said Peter Quick, Retail Media Manager at CDON Group. "We needed a solution that could integrate quickly, stay closely connected to our shopping experience, and scale alongside our business over time. With Topsort, we've been able to build a retail media foundation that feels native to how our marketplace operates, without inheriting unnecessary complexity." CDON Group connects consumers and merchants across a wide range of categories throughout the Nordic region, creating a highly dynamic marketplace environment where shopper relevance and seller performance are critical to long-term growth. "This partnership reflects a broader shift happening across marketplace commerce," said Regina Ye, CEO at Topsort. "Many marketplaces are realizing that legacy advertising infrastructure creates unnecessary friction when applied to marketplace ecosystems. What makes CDON Group particularly interesting is their focus on building commerce media in a way that feels native to the shopping experience from day one. They prioritized flexibility, scalability, and operational simplicity, which is exactly where we believe the market is heading." For Topsort, the partnership reinforces a broader thesis: commerce media infrastructure is evolving beyond legacy retail media models toward more modular, API-first systems designed for marketplaces, ecommerce platforms, and modern commerce environments where relevance, scalability, and integration speed are becoming increasingly important.
