Jules Minvielle

Today Minvielle spends his days on a problem most viewers never think about. When a brand wants to run an ad on connected TV, that decision passes through a tangle of demand-side platforms, supply-side platforms, publishers and measurement vendors that rarely speak the same language. Olyzon, the company he co-founded and now leads as chief executive, sits in the middle of that tangle as what he calls a decisioning and orchestration layer - agnostic across every DSP, SSP and publisher.

The pitch is technical, but the frustration behind it is plain. "CTV has scaled fast, as pipes multiplied, formats exploded, and measurement fragmented," Minvielle has said. "The decisioning layer never kept pace." Olyzon's answer is a set of AI agents that read a campaign brief and turn it into a structured connected-TV plan. The system parses bid-request data and electronic program guides to find contextually relevant shows, enriches the metadata, then generates the ad formats to match - interactive overlays, squeeze-backs, pause ads, QR codes.

What separates Olyzon from the crowd of companies now stapling "AI" to their decks is where Minvielle started. "I didn't want to put AI on top of something old," he said. "I wanted to build a company where AI is the foundation." It is a designer's conviction as much as an engineer's - the belief that the shape of the technology, the team and the strategy should all be drawn for where the industry is heading rather than where it has been.

A move made for the market

Olyzon keeps its headquarters in Paris, on Avenue Trudaine, but Minvielle relocated to New York to be closer to the largest connected-TV market in the world. The company co-founded with Martin Danet and Mathieu Desve in 2024 now works with a roster that reads like a Cannes guest list: Publicis, WPP, OMD alongside brands such as LVMH, BMW, L'Oreal, PepsiCo, IKEA, McDonald's, Audi, Mastercard and DoorDash.

Minvielle is candid about the behavior he is designing around. "Over 95% of viewers have a phone in hand while watching TV," he notes - a fact most advertisers treat as a nuisance and he treats as a brief. The interactive formats Olyzon generates assume the second screen is already there. The company reports attention rates as high as 99% through precise contextual placement, and leans on third-party partners for independent brand-lift studies rather than grading its own homework.

Waiting for the moment

Timing runs through everything Minvielle says. He argues the tools finally caught up to the ambition. "Now, AI agents that can finally reason across the chaos have reached production maturity," he said, "and that's exactly the moment Olyzon was built for." In May 2026 the market agreed with him: Olyzon closed a $10M Series A led by S4S Ventures, the fund co-founded by Sanja Partalo and Sir Martin Sorrell, with returning investor Eurazeo. An earlier $5M seed extension had been led by Cassius Capital.

Sorrell, who built WPP and later S4 Capital, framed the appeal in operator's terms: the platform "orchestrates" existing tools "with a speed and precision that human teams alone cannot achieve." Partalo said Olyzon "combines deep trading expertise with a purpose-built agentic architecture" to fill the missing intelligence layer in CTV buying. The new capital funds US operations and a London office, opened as the company pushes into EMEA ahead of Cannes Lions.

The pattern beneath the résumé

Olyzon is Minvielle's third act in adtech, and the through-line is consistency of instinct rather than reinvention. He co-founded Ogury in 2014, a global mobile adtech company built on privacy-first innovation, and served on its board. Before and around that he co-founded and co-led Mozoo, a digital creative agency for adtech mobile activation, as co-chief executive and president; it was acquired in 2023. He founded Surikate back in 2010. Each venture sat in the same unglamorous place - the connective infrastructure brands depend on but rarely see.

He trained for it in classrooms as international as his career. Minvielle earned a specialized master's in entrepreneurship at HEC Paris under its HEC Entrepreneurs label, studied entrepreneurship at Grenoble, and completed an MBA in project management on exchange at RMIT University in Australia. More than a decade later, the résumé still points in one direction: building the plumbing, then convincing an industry it needed it all along.
