What C Wire does
C Wire AG is a Zurich-headquartered AdTech company that has built an AI-powered, cookieless advertising platform operating across 9+ European markets (DACH core plus France, Italy, and Spain) from offices in Zurich, Düsseldorf, Vienna, and an engineering hub in Belgrade. Founded in 2020, the company's stack combines a semantic Signal & Context Engine, the trademarked MatchPersona™ persona-generation tool, an outcome-based bidder, and Buyer Pro programmatic activation via PMP/Curated Deal IDs inside the advertiser's existing DSP. The platform is integrated with 200+ DSPs (OpenRTB 2.6 + IAB TCF v2) and 500+ curated European publishers, processing 30B+ monthly impressions with reported 75%+ viewability.
C Wire serves two customer segments: (1) advertisers (brands and agencies) seeking identity-optional reach and cookieless contextual targeting across Safari, Firefox, and ITP-blocked environments — the company claims reach to 100% of addressable users versus the ~60% reachable via cookie-based approaches; and (2) premium European publishers looking to monetize cookieless traffic at higher eCPMs through curated deals and modern formats. The platform supports a portfolio of high-impact ad formats including Story Ads, Vertical Video, Native Immersive Units, Outstream Video, Spotlight Ad, Flex Cube Ad, and Gamification Ads.
Commercially, C Wire operates a dual go-to-market: (1) Programmatic via Buyer Pro — CPM-based PMP/Curated Deal activation where the advertiser retains its existing DSP, billing, and media-agency relationships; and (2) Managed Service — full-service campaign management with outcome-based pricing (CPM, vCPM, CPC, CPV, CPCV, CPE) and a dedicated persona strategist. A self-serve MatchPersona tool is offered for inbound/PLG motion. Enterprise customer logos include UBS, Mastercard, BMW, Mercedes-Benz, Porsche, Audi, Apple, IKEA, H&M, Nestlé, McDonald's, Miele, Swiss Post, and Glencore. The company is venture-backed (21 Celsius led its first external round in 2021; a 2023 seed funded bidder/SSP development and DACH expansion) and is currently raising a Series A in 2026 to scale the agentic stack and pan-European footprint.
