What Epsilon does
Epsilon operates a hybrid software, data and services model. It creates value by linking proprietary identity and data assets with enterprise marketing applications and activation tools, allowing customers to unify customer records, build audiences, run campaigns and measure outcomes in one ecosystem. It monetises both the underlying infrastructure and the execution layer, spanning SaaS modules, data access, clean room collaboration, programmatic buying, retail media enablement, publisher monetisation and managed campaign services.
Category differentiation
Epsilon is not a standalone consumer brand or a pure media agency. It is Publicis Groupe’s enterprise data, identity and activation business spanning adtech, martech and managed services.

Company news briefing

Companies Misalign AI Measurement with Customer Value
AI · Recorded impact score: 3/5
An opinion piece argues that most companies are measuring AI against internal productivity goals rather than customer value. Epsilon's 2026 benchmark study of 257 marketing decision-makers found 71% use AI for productivity, yet 46% measure its impact by revenue. The article highlights a perception gap between C-level and senior managers regarding AI maturity and value. It also cites data on AI's growing influence in search and retail traffic. The author suggests focusing on customer-centric outcomes and warns against treating AI as a strategy substitute. The piece includes insights from Gartner, Adobe, and Forrester on AI's effects.
- Epsilon's 2026 benchmark study of 257 marketing decision-makers found 71% primarily use AI for productivity, but 46% measure AI performance by revenue.
- Epsilon found 67% of C-level marketers rate their organization as extremely mature in AI, versus 33% of senior managers.
Brands Should Use Retail Media for AI-Led Discovery
Retail Media · Recorded impact score: 3/5
Esme Robinson of Epsilon argues that as AI-powered search and shopping agents change how consumers discover products, brands should invest in retail media to control the product narrative within retailers' properties. Retailers' first-party data and structured product feeds increasingly inform AI recommendations, so brands that build richer, text-led pages and brand experiences inside retail media environments can influence signals used by AI assistants, improve visibility during peak buying seasons, and create co-branding and promotional opportunities at point of purchase.
- Esme Robinson of Epsilon authored an opinion piece discussing retail media and AI-led discovery.
- The article states AI-powered search (e.g., Google AI, ChatGPT-style platforms) is shifting consumer queries toward context-rich questions and acting as a gatekeeper for discovery.
Shoppers Cut Non-essentials; Golden Quarter Competition Rises
Retail Media · Recorded impact score: 3/5
A new Epsilon report, based on two Censuswide studies, finds UK consumer intent for the Golden Quarter at £17.9bn, but shows widespread caution: 71% of shoppers say they are cutting back on non-essential spending and 68% are seeking lower prices. The research also notes ad spend is forecast to reach £50bn this year while audience growth is minimal and average daily online time has fallen. Marketers plan to prioritise performance (79% of Q4 spend) and many expect H2 budgets and Q4 sales to be up, but the report warns conversion risk if demand proves softer than expected.
- Epsilon's report projects £17.9bn of UK consumer spending intent during the Golden Quarter.
- 71% of shoppers reported cutting back on non-essential purchases; 68% are looking for lower prices.
