Topsort launches TikTok Offsite Ads to extend Commerce Media beyond onsite placements. May 18, 2026, 09:00 ET New AI-native capability allows marketplaces to operationalize TikTok advertising through the same commerce media infrastructure already powering onsite retail media. PALO ALTO, Calif., May 18, 2026 /PRNewswire-PRWeb/ - Topsort, an AI-native commerce media infrastructure company powering marketplaces and retailers worldwide, today announced the launch of TikTok Offsite Ads, a new capability that enables marketplaces and vendors to launch TikTok campaigns directly from the Topsort platform. As commerce discovery increasingly shifts beyond marketplace storefronts into short-form video and social feeds, marketplaces are looking for ways to extend retail media beyond onsite placements without creating disconnected advertiser workflows, fragmented attribution, or operational complexity. TikTok Offsite Ads extends Topsort's commerce media infrastructure into one of the world's largest discovery platforms, allowing marketplaces to manage onsite and TikTok offsite campaigns through the same catalog, campaign, and reporting infrastructure they already use today. "Commerce discovery is increasingly happening outside the storefront, but most marketplace advertising systems were built only for onsite monetization," said Regina Ye, CEO of Topsort. "TikTok Offsite Ads reflects where commerce media is going: unified infrastructure that connects onsite and offsite discovery into one operational system." Bring TikTok Into Your Commerce Media Infrastructure TikTok Offsite Ads allows marketplaces and vendors to launch campaigns using workflows already familiar from onsite sponsored listings and other offsite programs inside Topsort. Advertisers can: * Select all products or specific SKUs * Set budgets and campaign dates * Launch TikTok campaigns directly from Topsort * Use the same catalog infrastructure already powering marketplace retail media * Review SKU-level and campaign-level reporting through existing Topsort workflows To simplify campaign creation, advertisers can also choose soundtrack styles including Relaxed instrumental, Upbeat electronic, and Minimal ambient, while Topsort automatically selects an appropriate instrumental track from TikTok's music library. The launch extends Topsort's AI-native commerce media infrastructure into TikTok campaigns, helping marketplaces manage onsite and offsite monetization through the same catalog, campaign, reporting, and attribution workflows already used across their retail media programs. As marketplaces expand into social commerce and omnichannel discovery, they increasingly need infrastructure that can connect advertising surfaces without adding operational complexity. TikTok Offsite Ads is available now for Topsort marketplace customers. Media Contact SOURCE Topsort
Topsort partners with Avolta to power commerce media across global travel retail. * Business Wire * May 13, 2026 * 0 PALO ALTO, Calif.-(BUSINESS WIRE)-May 13, 2026- Topsort today announced a partnership with Avolta, the leading global travel retail and food & beverage operator, to power commerce media across its global footprint, marking a major expansion of Topsort's commerce media infrastructure into global travel retail and F&B. Retail media started on ecommerce shelves. But commerce doesn't just happen online. It happens when a traveler buys fragrance before a flight, grabs coffee between gates, or shops duty-free after security, where attention, context, and purchase intent come together in a physical environment. Following Topsort's work with Despegar, one of Latin America's largest online travel agencies, the Avolta partnership represents a new level of operational complexity: global scale, in-store environments, airport retail, duty-free, convenience, and selected food & beverage touchpoints. Travel media is quickly becoming one of the most important frontiers for commerce media. Unlike traditional ecommerce retail media, travel retail connects digital and physical shopping moments across airports, terminals, stores, adjacent traveler experiences, and high-intent passenger journeys. "As we continue to evolve our commercial and digital capabilities across Avolta's global footprint, building a scalable and flexible approach to commerce media is a clear priority," said Richy Ugwu, Global SVP Advertising & Commercialization at Avolta. "We were particularly impressed by Topsort's ability to handle the complexity of our environment - from multiple markets and store formats to the integration of physical and digital touchpoints. We needed infrastructure that could scale globally across our travel retail and food & beverage network, and Topsort stood out in that regard." Avolta is the leading global travel retail and F&B player which operates across six continents, with a presence in 70 countries and close to 5,100 outlets worldwide. "This partnership reflects a broader shift we're seeing across the market," said Regina Ye, CEO at Topsort. "Travel is becoming one of the most strategically important environments for commerce media globally. What makes Avolta unique is the combination of scale and complexity - multiple countries, store formats, and high-intent moments across the traveler journey. When operators at that level choose to invest in commerce media infrastructure, it signals that this is becoming a core capability, not an experiment." For Topsort, the partnership reinforces a broader thesis: commerce media is expanding beyond online marketplaces and grocery into every environment where discovery, intent, and transaction data meet - including travel retail and broader physical commerce environments at global scale. About Topsort Topsort is the commerce media infrastructure company helping retailers, marketplaces, and commerce platforms build scalable, transparent media monetization systems powered by auctions, first-party data, and measurable outcomes. Today, Topsort provides monetization infrastructure to leading enterprises across more than 40 countries, including Coles, DoorDash, Woolworths, and Falabella. About Avolta Avolta is a global leader at the intersection of travel retail and food & beverage, delivering integrated shopping and dining experiences across airports, motorways, cruise lines, ferries, rail and other high-traffic travel locations worldwide. Avolta operates in more than 70 countries and across nearly 1,000 locations, managing around 5,100 points of sale. Its traveler-centric strategy is built on digital, data and continuous innovation.

Topsort, an AI-native retail media infrastructure company, has launched In-Store Ads, a self-service ad format that integrates physical retail inventory into the same workflow as online retail media. The platform enables marketplaces and advertisers to manage in-store digital screen campaigns through Topsort's existing infrastructure. The new capability addresses operational challenges in physical retail advertising, which typically relies on manual coordination and fragmented tools. In-Store Ads standardises campaign setup, creative handling and reporting within a single system, allowing vendors to launch in-store campaigns from the same dashboard used for online media. The format aims to accelerate campaign launches, increase advertiser participation and improve inventory transparency whilst maintaining marketplace control. Retail media teams can now run both onsite and in-store campaigns through unified infrastructure, including budgeting and reporting.
Topsort, an AI-native retail media infrastructure company, has launched Tomi, an AI agent that enables marketplaces to create and manage sponsored listing campaigns using natural language. The tool allows users to describe campaign objectives conversationally rather than manually configuring settings. Embedded within Topsort's marketplace admin interface, Tomi can identify products, configure campaign settings, apply targeting rules and set budgets based on plain-language prompts. The company claims teams can launch campaigns up to five times faster whilst maintaining full control through review and approval workflows. Tomi currently supports keyword, category, competitor-page and always-on targeting strategies for onsite sponsored listing campaigns. The tool is available to Topsort customers by request. Topsort provides monetisation infrastructure to enterprises including Coles, DoorDash and Woolworths across more than 40 countries.
