Topsort
Topsort is a retail media infrastructure software for marketplaces, retailers, brands, and agencies.
Analyst Perspective
Topsort is a private US ad tech company focused on retail media infrastructure for retailers, marketplaces, publishers, brands, and agencies. Its product suite includes software for ad serving, retail media network enablement, demand-side buying, supply-side monetisation, private marketplace deals, optimisation, analytics, and commerce data intelligence. The company positions itself as an integrated stack that helps commerce platforms launch and run advertising businesses across onsite, offsite, social, web, and in-store environments. The company makes money by selling software access to its platform and related modules, and likely by charging usage-based or transaction-linked fees tied to ad serving, auctions, media spend, and infrastructure consumption. Its direct paying customers are businesses rather than consumers, especially retailers and marketplaces building media networks, as well as advertisers and agencies buying inventory through its demand tools.

Key insights about Topsort
Category Differentiation
Topsort is a B2B retail media and advertising infrastructure vendor, not a consumer shopping app or a retailer itself. It is best distinguished from general ad tech platforms by its commerce and retail-media-specific infrastructure focus.
Topsort: About
Topsort operates a B2B ad tech and software model. It provides a modular retail media stack to commerce platforms that want to create or expand advertising revenue streams, alongside demand-side tools for buyers and optimisation layers for monetisation teams. Value is created by reducing the technical complexity of launching ad infrastructure, improving auction efficiency, and enabling retailers and marketplaces to commercialise first-party commerce data across owned and external channels.
How Topsort Works & Monetises
Business model analysis and core revenue streams
The commercial model is primarily SaaS and infrastructure software, with platform access and module-based monetisation across ad serving, retail media enablement, analytics, and optimisation. The product data also supports likely usage-based charging tied to impressions, auctions, API calls, or spend processed, plus transaction-linked economics within its DSP and SSP workflows. In practice, Topsort appears to combine subscription revenue with variable platform and media-transaction revenue.

Google, Meta, Unity Invest in AppsFlyer; TV Brand Integrations
AppsFlyer has agreed a funding deal with Google, Meta, Unity and Moloco in which each investor takes a minority, non-controlling stake. AppsFlyer did not disclose the amount; Axios, citing people familiar with the financing, reported the round exceeds $1 billion and values the company at $2.7 billion — a figure also repeated by Crunchbase referencing Axios. AppsFlyer says investors will not receive preferential access to APIs, measurement signals, attribution logic or commercial terms, and customers will retain control over partner connections and data sharing. The company intends to use the new capital to accelerate AI-driven advertising measurement, cross-platform attribution and agentic workflows. AppsFlyer serves more than 15,000 brands; the transaction provides liquidity to existing shareholders, may include further strategic partners in later closings, and remains subject to typical closing conditions and regulatory approvals.
