- Olyzon
Led · Series A · May 2026
Olyzon builds an agentic decisioning layer for connected TV (CTV) advertising that uses AI agents to qualify the CTV universe, plan media across pipes, activate decisions into DSPs/SSPs and publisher ad servers, and normalize measurement into composite KPIs. Its platform is already deployed with major agencies and brands, including Publicis, WPP, OMD, Mastercard, Loewe, Audi, McDonald's, and DoorDash. The company emphasizes orchestration rather than replacement of existing DSPs and measurement partners, claiming its agents close the optimization loop across planning, activation, and measurement. Olyzon is headquartered in Paris and maintains offices in New York and London. The recent $10 million Series A led by S4S Ventures and participation from Eurazeo will fund U.S. expansion, the opening of a London office, product milestones, and global team growth. The company plans to share further product and partnership updates at Cannes Lions.
