Criteo

One of the largest independent commerce media platforms globally, with a leading position in retargeting and a growing retail media network serving brands, agencies, retailers, and publishers.

Criteo is a digital advertising company that enables businesses to target and retarget potential customers through personalized display advertisements.^1,2 Its commerce data and AI technology connect media impressions with over one trillion commerce transactions, helping advertisers find the right audiences and deliver relevant messages based on shoppers' complete purchase journeys.³ Criteo serves multiple sides of the advertising ecosystem: it helps retailers monetize their audiences as media companies, supports brands and agencies in driving awareness and sales across media and sales channels, enables publishers to connect content consumption to commerce, and uses AI-driven audiences and creatives to bring new and lapsed customers to marketers.³ Historically associated with ad retargeting, Criteo is now repositioning for an AI-driven commerce era, running early experiments with large language models and piping structured commerce signals into LLM environments via a Model Context Protocol server, so that agents inside tools like ChatGPT or Claude can draw on Criteo's data when recommending products.⁴ The company's dataset encompasses 720 million daily active users, more than one trillion dollars in observed online transactions, and billions of SKUs integrated across retailers and brands.⁴ In June 2023, the French data protection authority fined Criteo 40 million euros, notably for failing to verify that individuals whose data it processes had given their consent.¹ Source 1: wikipedia.org — Criteo Source 2: lunio.ai — What is Criteo Used For? | How to Use Criteo?
