Olyzon Raises $10M to Automate CTV Ad Buying

The big picture: Olyzon, a Paris-based adtech company, has raised $10 million in Series A funding. The company uses AI agents to manage media buying decisions across connected TV, aiming to streamline a fragmented market.

Why it matters:

• Rapid Growth, Stagnant Tools: U.S. spending on CTV ads reached $33.35 billion in 2025, yet campaign management remains manual, relying on disparate measurement systems and planning workflows.
• AI Orchestration: Olyzon’s platform layers on top of existing ad tech stacks, using AI agents to orchestrate demand-side platforms (DSPs), supply-side platforms (SSPs), and direct publisher ad servers.
• Real-time Optimization: The system automates inventory assessment, placement selection, and performance data consolidation, learning from each campaign to optimize future decisions and connect ad exposure to business outcomes.

How it works:

• Agentic AI: Olyzon’s AI agents assess available inventory at the program level, score placements based on predicted performance, align creative formats, push decisions into the buyer’s existing tools, and measure outcomes.
• Seamless Integration: The platform is designed to sit on top of existing ad tech infrastructure, including DSPs and SSPs, rather than requiring buyers to abandon their current tools.
• Autonomous Decision-Making: The investment will fund continued development of the platform’s autonomous capabilities, aiming for AI to handle the full cycle of media buying, from planning to execution and real-time adaptation.

The catch: The adtech market, particularly for CTV, is highly competitive and fragmented, with numerous established players and emerging solutions. While Olyzon’s approach of layering an AI intelligence layer on top of existing infrastructure is strategic, integrating and ensuring consistent performance across a multitude of disparate systems presents significant technical and operational challenges. Adoption by large agencies and brands, despite the platform’s benefits, may be slow due to entrenched workflows and existing vendor relationships.
