Epsilon

What Epsilon does

Epsilon is a marketing technology company founded in 1969 and headquartered in the United States, operating today as a wholly-owned subsidiary of Publicis Groupe S.A. The company sells Epsilon PeopleCloud, a unified marketing platform anchored by CORE ID, an identity resolution solution spanning 200+ million U.S. consumers. Built on more than 50 years of accumulated proprietary data assets, PeopleCloud organizes around three capabilities: 1 View (unified customer data), 1 Vision (personalized messaging strategy), and 1 Voice (cross-channel orchestration across paid, owned, and earned media). Sub-modules under the platform include PeopleCloud Customer (CDP), PeopleCloud Clean Room / Prospect (privacy-safe data collaboration), PeopleCloud Loyalty, PeopleCloud Messaging (email/SMS), Epsilon Digital (programmatic and CTV media), Epsilon Retail Media, Accelerate (web personalization), and Signals (real-time intent modeling).

Epsilon's go-to-market is enterprise B2B field sales targeting Fortune 500 and large global brands, supported by strategic technology partnerships with Adobe (key identity partner, integrated into Adobe Experience Platform), Microsoft (Azure preferred cloud, Copilot deployment across Publicis's 114,000+ employees, global media agency of record), Databricks (launch partner for agentic CustomerLake CDP), and Salesforce, plus sister-agency distribution through Publicis Sapient and Publicis Media. Revenue mechanics blend platform/subscription licensing (PeopleCloud), digital media spend activation (CORE ID-powered display, programmatic, and retail media), data and identity monetization, and professional services for strategy, implementation, and campaign execution. Pricing is quote-based, annual, and varies by consumer profile reach, channels activated, and module scope.

The company serves eight primary verticals — Retail, Restaurants/QSR, Health/Pharmacy, Financial Services, Auto, CPG/Beverage, Travel/Hospitality, and Nonprofits — with documented enterprise engagements including Ulta Beauty (42M loyalty members), Walgreens (105M active members, Walgreens Advertising Group), Dunkin' (9,000+ POS-connected locations, 24M+ DD Perks), Marriott, Coach, BP, Anheuser-Busch, Valvoline, Norwegian Cruise Line, Jersey Mike's, and a leading U.S. bank. Epsilon employs more than 8,000 people across 40+ offices globally, including approximately 3,000 in a Bengaluru technology hub that supports engineering, data science, and platform operations. Recent inorganic moves include the Retargetly acquisition (LATAM launch, 2022), Yieldify (2023), Influential (2024), and the pending $2.2B LiveRamp acquisition by parent Publicis.
