AI Pioneer Alex Lebrun Slams EU Rules, Reinvents Doctors With Assistants
Alex Lebrun, three-time AI founder and CEO of Nabla, reflects on two decades building chatbots and how large language models have finally reached viable market timing. He argues that generative AI applications are far from a thin layer on foundation models, stressing the deep technical and product advantages of understanding and orchestrating LLMs. A major focus is healthcare: he believes AI won’t replace doctors, but doctors using AI will outperform those who don’t, primarily through automated clinical documentation and ambient assistants. Lebrun also criticizes the EU’s proposed AI Act as disastrously out of touch, predicts open models will dominate, and warns Europe will fall further behind the US and China unless regulation becomes more realistic and better informed.
Key Takeaways
Deep expertise with LLMs is a durable edge even on shared infrastructure.
Lebrun insists that knowing how models are built, where they fail, when to swap them, and how to wrap them with additional ML is a major competitive advantage; applications are not just a “thin layer” on top of public models.

Proprietary data matters less than before; small, high‑quality datasets can be enough.
He notes modern pre-trained models can be fine-tuned effectively with surprisingly small but well‑curated datasets (e. ...

AI will radically augment clinicians before it replaces them.
Nabla focuses on ambient AI assistants that listen to consultations, auto‑generate documentation, and integrate with EHRs, freeing doctors from admin work that currently consumes ~49% of their time and drives burnout.

Healthcare startups must start from “who pays,” not just “what problem.”
Because payers, providers, and patients are misaligned, he argues founders must begin by identifying the paying stakeholder and designing a solution and problem framing that fit existing reimbursement structures.

Regulating AI too early and too strictly could cripple Europe’s competitiveness.
Lebrun calls the EU AI Act a disaster, saying requirements like full licensing for all training data would make nearly all current LLMs illegal, pushing serious AI work out of the EU and delaying Europe by decades.

Incumbents will add “AI dust,” but true disruption will come from new paradigms.
He expects large firms to bolt on AI features to existing products (e. ...

Cultural and structural factors still hold Europe back in scaling AI companies.
Lebrun points to European founders selling too early, weaker growth discipline, and now heavy-handed regulation as reasons Europe lags the US and China, despite having world‑class math and ML talent.

Will AI replace doctors?
So AI will not replace doctors, but doctors who use AI will replace doctors who don't. (instrumental music)
Alex, I am so excited for this. I've been looking forward to this one for a long time. I've been thinking with a couple of the AI shows, I can't wait to do this in person with Alex. So thank you so much for joining me today.
Thanks, Harry.
Now, I would love to start with a little bit of context because we're three startups in at this point. So take me back, how did you first make your way into the world of startups?
So, um, 22 years ago, I, I fell in love with a chatbot. Her name was Sibyl.
(laughs)
And really, really, I was, you know, summer night in Paris in my basement alone with my computer. And I, I, I, I found-
This could go in many directions. (laughs)
(laughs) Right. Up to you. Um, and, uh, I was mesmerized by this chatbot, you know, the fact that the machine is trying to understand you, language, and can generate some words. And I, I was really, really struck by this thing and I decided I would, okay, I would spend my life building, uh, chatbots. And so I founded, um, a company doing customer service bots 22 years ago, very early, um, called Virtuozz. And this is how I started, um, you know, this series of companies in the, in the domain.
Can I ask you, given it was 22 years ago, and I know this is off schedule straight away, but just how do you think about market timing today?
Well, for, for 20 years, you know, when, when we started, uh, I thought chatbots would become very, very intelligent after three, four years and get to AGI and replace humans in call centers. And the more I worked on the problem, the more I realized it was really, really difficult to do that. Actually, the first time we released a bot in Europe was in '24, uh, 2004, to the French railway company. And we were very, very happy to, to have this customer, and the deputy CEO tried it. And she, she asked, "My name is wrong on the, on the reservation." And the, our bot answered, "Hello. Wrong on the reservation." And then we realized, okay, there is still a lot of work. (laughs) It's not smart at all. And so the more I worked on these things, the more I realized it's not ready yet. And so suddenly for the last year, two years, uh, we reach a point where market timing might, might be finally, um, finally good, you know, where the product is ready and people have evolved too, maybe 10 years after Siri, people have changed-
Mm-hmm.
... and they, they are ready to meet this kind of technology. So maybe the market timing is now.
