What is Cleon?
In ancient Athens, Cleon was more than a man, he was a historical force. Known for his fierce rhetoric, populist power, commercial reach, and commanding presence in the public marketplace, he understood how influence shaped value. Inspired by that legacy, Cleon.tv is the digital agora of advertising: a plug-and-play monetization engine for video, display and native ads, in one unified platform.
Cleon is a next-generation ad platform designed specifically for publishers. At its core lies a fully-featured ad server that supports all major ad formats, giving you a single, centralized place to manage, serve, and optimize every monetization opportunity on your site. Cleon integrates advanced programmatic technology, direct ad sales tools, PMP deals, and native video capabilities — all within a clean, user-friendly interface.
Unlike legacy ad servers that are built around agency workflows, Cleon was built from the ground up to solve publisher problems. It helps you maximize your revenue, reduce your reliance on third parties, and maintain control over both your data and your user experience.
Core Benefits
All Formats. One Ad Server.
Cleon supports the full spectrum of advertising formats — including Display Banners (standard and sticky), Interstitials (full-screen ads), Rewarded Ads (for gated content), Native Ads (that blend seamlessly into content), and both Outstream and Instream Video Ads. You can mix and match formats, define rules for placements, and deliver them all through a single line of code.
Smart Video Infrastructure
Many publishers struggle with monetizing their video content because they rely on platforms like YouTube. Cleon changes that by giving you your own video infrastructure. Host videos on Cleon, embed them on your site with a customizable player, and serve video ads (pre-roll, mid-roll, post-roll) with full VAST/VPAID compatibility. Even if your site doesn’t produce its own videos, you can still monetize editorial content with autoplay outstream video ads.
Direct Sales, PMP & Programmatic
Cleon is the only platform you need whether you're selling ads directly to clients, setting up curated Private Marketplace (PMP) deals with agencies, or participating in automated auctions via the Open Marketplace. You can configure buyer targeting, set pricing floors, and prioritize premium partners — or let Cleon optimize for you.
Live Data, Transparent Reporting
Cleon gives you access to real-time analytics dashboards that track performance metrics across formats, devices, and geographies. You'll see impressions, viewability rates, click-through rates (CTR), video completion rates, and revenue — all in one place. The system also includes fraud protection and audience integrity monitoring so that you know exactly what you’re earning and from where.
Plug & Monetize in Minutes
Cleon was built for speed and simplicity. You don’t need developers, backend integrations, or complex setup. Just copy a code snippet, paste it into your site, and immediately start serving ads. Campaign creation, ad placement, optimization and tracking all happen in the Cleon dashboard.
