Meet The Co-Founders
Two Paths, One Purpose: The Founding Duo Behind AI ON US
Thomas Lozopone & Marianne Mazaud – Bridging Innovation and Responsibility
From global marketing strategy to world-class event design, Thomas and Marianne combine their expertise to build a space where Responsible AI becomes reality. Their partnership fuels AI ON US with both strategic clarity and a deep commitment to ethical AI.
If you're tired of noisy expos, generic trainings, or AI talks that feel out of touch—we built this for you. If you want AI to serve people—not the other way around—you belong here. Because Responsible AI doesn’t slow you down. It makes you unstoppable.
Our Mission
Helping Global Leaders Leverage AI Responsibly—To Lead with Trust, Not Fear
At AI ON US, we are not anti-innovation—we are pro-intelligent transformation. We believe AI holds the power to solve the world’s biggest challenges—but only if the people at the top understand how it works, what its risks are, and where it actually adds value. Trust issues around AI are real—and rising. This is what highlights the latest global study on AI and public trust conducted by the international consulting group KPMG, reflecting views from over 48,000 people across 47 countries and underscoring a global gap between rapid AI adoption and governance.
Over 54% of respondents are wary of trusting AI, with trust significantly lower in advanced economies (39%) versus emerging ones (57%). While 72% accept AI use, 61% lack formal training and half report limited knowledge. Concerns span cybersecurity, job loss, misinformation, and human disconnection. Only 43% believe current laws are sufficient, though 70% believe regulation is necessary—especially to counter AI-generated misinformation (87%). At work, 58% of employees use AI regularly and intentionally, over half of employees report performance benefits from AI but also flag risks like policy breaches and overdependence. Governance and training to support responsible AI use appears to be lagging adoption. Among students, 83% (predominately tertiary) regularly use AI in studies, yet only 50% say their institutions provide responsible use training.
This erosion of confidence isn’t just an AI issue—it’s a business risk that spans sectors. Because when people no longer trust the technologies powering your services, they stop buying.
That’s why we bring together Tier 1 business leaders, policymakers, compliance experts, and innovators across the U.S., Europe and LATAM—to reconnect innovation with compliance, and show how AI can be used not just ethically, but competitively.

Why It Matters Now
Too often, conferences separate the "policy people" from the "product people." Academics and lawmakers gather in one room; startup founders and scale-ups gather in another.
We bring them together.
AI ON US is not a conference. It’s a turning point. It’s your chance to:
-
Ask the hard questions—before your regulators do.
-
Reconnect your strategy with your stakeholders’ trust.
-
Get the insights your competitors wish they had.
We give you the space to think, engage, and prepare—without queues, overwhelm, or distractions.
Marianne Mazaud
From Creativity to Code: Why I Co-Founded AI ON US
Hi, I’m Marianne—Co-Founder & Co-CEO of AI ON US, a summit and strategic content platform helping C-level leaders navigate Responsible AI.
Over the past 10+ years, I’ve led global marketing and creative performance strategies across the fashion, beauty, wine, and tech industries—working with 25+ international brands like Puig, Take-Two Interactive, Stillfront Group, and Outplay Entertainment. From Biarritz to New York to Barcelona, I’ve helped teams deliver top-performing digital campaigns across continents. But things changed in 2022.
As deepfakes began flooding ad networks, I saw first-hand how AI could become a risk—not a tool. Brands pulled out. Legal teams panicked. Creative work was halted. That was my turning point. I didn’t want to just market tech—I wanted to understand it, build it, and fix what was broken.
So I went back to school. After completing my MSc in Digital Marketing at NEOMA Business School, in (2015,) I earned a second Master’s in Artificial Intelligence from IA School (2024), where I learned to code in Python and built detection pipelines to spot deepfakes, scams, and synthetic content with the ultimate goal to fight against Fake Ads for Global Brands.
But the more I learned, the more I realized: technology alone won’t fix the trust crisis. We need a new kind of leadership.
That’s why I co-founded AI ON US with Thomas—a summit created not for headlines, but for impact. I spent six months assembling a global AI Expert Committee of 20+ researchers, lawyers, and technologists from the US and Europe. Together, we designed 10 Responsible AI teams to deliver high-impact content—no fluff, no repeats, just strategic clarity. And to do so, I joined ALL TECH IS HUMAN mentorship program to seek guidance and challenge our visions.
What I do at AI ON US: I lead the global marketing, event and content strategy, build international partnerships, design immersive workshops, and co-host our 10-minute YouTube series AI ON US x CTO News Thursday, which I also produce and edit.
My goal? To empower senior executives with actionable insights—so they can scale AI responsibly, avoid costly mistakes, and build long-term trust with users, regulators, and communities. Because in the age of Responsible AI, the cost of shortcuts is too high—and the reward of getting it right is even greater. I speak French, English, and Spanish—so feel free to reach out in your language.
Let’s make AI work for people, not just for machines.
Thomas Lozopone
From B2B Excellence to Cultural Movements
Hi, I’m Thomas—Co-Founder & Co-CEO of AI ON US. I’ve always believed that the most meaningful conversations happen not in giant halls—but around a table with the right people in the room.
Before co-founding AI ON US, I spent 5 years living and working in Montréal, Canada, where I specialized in B2B event production—from international culinary showcases to wine and spirits salons. My background is deeply rooted in crafting immersive, high-end experiences that blend precision with emotion, and logistics with storytelling.
When I moved back to the Basque Country, my native region, I started joining Marianne—my Co-Founder and the creative brain behind AI ON US—at tech and AI conferences across France. And we kept asking the same question: Why is everything centralized in Paris? Why not create something truly different—a thoughtful, intimate, and world-class summit right here in Biarritz, where the pace slows down and connections go deeper? That’s how AI ON US was born.
Today, I’m the operational backbone of the summit. I handle: the logistics (venue, catering, production, tech setup), our financial planning and local partnerships in France, and the French business development strategy—ensuring AI ON US resonates beyond big cities and builds bridges with regional decision-makers.
I bring a meticulous, behind-the-scenes savoir-faire—focused on precision, ambiance, and guest experience. Together, we make sure every detail of the summit feels curated, effortless, and unforgettable.
I'm also a long-time enthusiast of emerging tech—from blockchain to crypto and now Responsible AI. To me, what we’re building isn’t just an event. It’s a platform to reconnect with what really matters in tech: trust, human dialogue, and shared progress.So whether you're joining us from Paris, New York, or London—bienvenue à Biarritz. You’re in for something truly special.
