Olyzon Raises $10M Series A for CTV Ad Tech

Olyzon, a Paris-based innovator in connected TV (CTV) advertising technology, has successfully closed a $10 million Series A funding round. The investment was spearheaded by S4S Ventures, the venture capital firm co-founded by advertising veteran Sir Martin Sorrell and Sanja Partalo. This significant capital infusion will fuel the company's expansion, particularly its U.S. operations, and establish a new office in London in anticipation of the upcoming Cannes Lions festival.

The core of Olyzon's offering is an advanced agentic decisioning layer designed to bring intelligence and automation to the increasingly complex CTV media buying process. The platform aims to streamline fragmented advertising workflows by enabling AI agents to autonomously handle media qualification, strategic planning, campaign activation across diverse platforms (including DSPs, SSPs, and publisher ad servers), and sophisticated measurement consolidation into key performance indicators. This approach addresses the growing challenges brands and agencies face in navigating the fragmented CTV ecosystem.

Industry leaders are taking notice of Olyzon's potential. Sir Martin Sorrell highlighted the company's strategic position at the nexus of AI advancements and the programmatic consolidation of CTV. He emphasized that Olyzon's platform enhances, rather than replaces, existing infrastructure, orchestrating operations with unprecedented speed and precision. Sanja Partalo echoed this sentiment, noting the critical gap in the CTV media buying stack for a unified intelligence layer that connects planning, activation, and measurement. She pointed to Olyzon's ability to deliver tangible results for major clients as a testament to its efficacy.

The Series A round also saw participation from existing investor Eurazeo, alongside other undisclosed backers. This continued support underscores confidence in Olyzon's vision and execution. The company's technology is already being utilized by a prestigious roster of clients, including major advertising holding groups like Publicis and WPP, leading media agencies such as OMD, and global brands including Mastercard, Loewe, Audi, McDonald's, and DoorDash. This broad adoption across different sectors validates the platform's versatility and impact.

The CTV advertising market is experiencing rapid evolution, characterized by increasing programmatic adoption, a proliferation of measurement solutions, and a growing reliance on AI for operational efficiency. Olyzon's platform is strategically positioned to capitalize on these trends. The company's CEO, Jules Minvielle, stated that the platform was developed precisely for this moment, where AI agents are mature enough to reason across the chaos of multiplying pipes and exploding formats in CTV advertising.

Olyzon's expansion plans include strengthening its presence in the United States, where CTV advertising spend is projected to reach significant figures in the coming years, and establishing its London base to better serve European clients and engage with the global advertising community. The company's focus on managing media buying across premium streaming services, YouTube, OEM ecosystems, walled gardens, and direct publisher inventory provides a comprehensive solution for advertisers seeking to optimize their CTV investments.
