What Herezie does

Herezie is a Paris-headquartered, privately held independent advertising agency founded in 2010 by Andrea Stillacci (CEO) and Pierre Callegari (COO), operating with a team of 65 creative professionals. The agency delivers full-service advertising across film, print, digital, social media, DOOH, radio and experiential activations, paired with brand strategy and an in-house TV production capability led by Félix Lenoir. Its client base is concentrated at the enterprise end of the market and spans streaming (Prime Video), luxury automotive (Maserati), telecom (Free), health technology (Doctolib), travel (KAYAK), used-car retail (Spoticar), consumer goods (Vileda, Triumph), financial services (Paylib, Cofidis), technology (Google), education (Superprof), champagne (Charles Heidsieck) and NGOs (Handicap International, Observatoire des inégalités).

The agency's underlying technology stack is conventional for a creative services firm: it operates as a professional services business with no proprietary software platform, no AI/ML product, and no app surface. Revenue is generated through project-based fees, campaign retainers, and production services typical of full-service advertising agencies. Go-to-market is primarily direct enterprise engagement via senior leadership and a dedicated Head of New Business (Leslie Hatchwell), supplemented by award-competition reputation, industry event participation (including hosting the By The Network global council), and earned media coverage in outlets such as AdAge and Le Figaro.

Strategically, Herezie positions itself as "the most awarded independent agency in France," with 99+ international awards across Cannes Lions, D&AD, The One Show, Clio, Eurobest, LIA and Andy, including AdAge International Small Agency of the Year 2023 and a Cannes Gold in 2023. Geographic reach spans 28 markets, increasingly delivered through partnerships within the By The Network independent agency alliance and bespoke creative alliances such as the "777" joint entity with Italy's Armando Testa (used to deploy Spoticar across 14 European countries). In September 2024, the founders announced a leadership reorganization, appointing a new Managing Director, two Creative Directors and a Director of Strategic Planning, framing it as a deliberate next chapter for the firm.

• Buzzman: Independent French creative agency known for bold, award-winning campaigns (Decathlon, Burger King). Comparable to Herezie in independent positioning, creative reputation and French enterprise client focus.
• Fred & Farid: Independent French-founded creative agency with Paris and Shanghai offices. Highly comparable to Herezie as an independent, award-winning shop pursuing bold creative for premium brands (Hermès, Tiffany, Hennessy).
