Accelerating U.S. Growth on a Strong Foundation

The new capital will support product development and deepen the company's presence in the U.S. market.
"CTV is the epicenter for premium attention—but most ad infrastructure hasn't evolved beyond display-era logic," said Jules Minvielle, CEO and co-founder of Olyzon.

At Nissan, Media & Advertising Manager Julien Dobisz said: "We have recently decided to integrate Olyzon into our marketing strategy. This solution captures the audience's attention in an immersive and engaging environment with precise targeting, while providing detailed insights to measure the effectiveness of our advertising investments."
To support U.S. expansion, the company recently appointed Zach Sorscher as SVP of Sales, U.S. An adtech veteran (former Exte, MiQ), Sorscher is leading commercial development in North America.
CTV: A market in rapid transformation
In the U.S., CTV is rapidly becoming the dominant video advertising channel. By 2025, it will reach over 238 million users and generate more than $30 billion in revenue, with double-digit annual growth (source: eMarketer).
Yet despite this momentum, tools inherited from display advertising have failed to keep pace with marketer expectations—they cite legacy technologies as lacking contextual relevance, failing to provide needed inventory transparency, and requiring complex and burdensome processes to scale. Olyzon was built to close these gaps and attract scale—enabling brands to deploy AI agents that execute brand goals autonomously on behalf of their specific goals in CTV, delivering frictionless results.
