Kyber was at VivaTech
Kyber at VivaTech 2026: Four Days of demos, media coverage and real conversations
VivaTech 2026 is over, and it was one for the books. For four intense days, the Kyber team was on the floor of Europe's biggest tech event, showcasing our real-time infrastructure technology to engineers, founders, investors and innovators from around the world.
Here's a full recap of what happened, who we spoke to, and why this edition mattered for us.
Why Kyber was at VivaTech 2026
VivaTech is where the conversations that matter happen. Robotics, drones, XR, AI agents, sovereign infrastructure, real-time systems, these aren't niche topics anymore. They're at the center of where tech is heading, and VivaTech's 10th anniversary edition reflected that better than ever.
For Kyber, being there was a natural step. We build ultra-low latency real-time infrastructure for the Physical AI era, the technology that lets robots, drones, XR systems and autonomous machines be controlled remotely with near-instant responsiveness. VivaTech is precisely where the people who need that technology come to explore what's next.
We set up on the booth of our partners and friends at Scaleway, in Hall 7.3, Booth 3F10, and spent the week running back-to-back live demos for visitors who came to see Kyber in action.
Jean-Baptiste Kempf at VivaTech: on stage, on air, and in the press
On stage with Inria
Jean-Baptiste Kempf, founder of Kyber and one of the lead developers behind VLC, took the stage at VivaTech for a talk titled "From Coding to Prompting", in partnership with Inria, the French national research institute for digital science and technology.
The talk tackled two of the most pressing questions facing the tech industry today:
What does AI mean for engineering teams? As large language models become capable of generating production-grade code, the role of the developer is fundamentally shifting. Do organizations still recruit engineers the same way? Do they still recruit them at all?
What happens to the tools and infrastructure we've built everything on? Software forges, dev pipelines, cloud infrastructure, all of it is being rethought as the way we build software changes at its core.
These aren't hypothetical questions. For a founder like Jean-Baptiste, who has spent decades building critical open-source infrastructure, they are deeply practical ones.
BFM Business, Tech & Co
On Monday June 22nd, Jean-Baptiste Kempf joined François Sorel on BFM Business for the daily Tech & Co show, alongside Thomas Serval (CEO of Baracoda), Jean Schmitt (President of Jolt Capital), and Hugo Borensztein (co-founder and President of Omi).
The panel debriefed on VivaTech's 10th edition: Jeff Bezos' highly talked-about appearance at the show, their personal highlights among the innovations on display, and the long-term outlook for this key European tech event.

BSMART 4Change
Jean-Baptiste Kempf also appeared on BSMART 4Change, further extending Kyber's media presence during the event week.
TechCrunch
Kyber's story caught the attention of TechCrunch, who published a feature on Jean-Baptiste Kempf and the technology he's building, tracing the line from VLC, the world's most popular free video player, to real-time infrastructure for robots and physical AI systems.
Four days of demos and business conversations
Beyond the media moments, the week was defined by the conversations on the floor.
We ran continuous live demos throughout the four days, giving visitors a hands-on look at what Kyber's real-time stack can do, video, audio, sensor data and control inputs, all handled with single-digit millisecond latency across cloud, hybrid and edge environments.
The conversations spanned the full spectrum: potential partners exploring integration opportunities, customers looking to understand how Kyber fits into their stack, founders comparing notes, and engineers asking the hard technical questions. That mix, the density and diversity of it, is what makes VivaTech unlike any other event.
It also came at a significant moment for us: Kyber recently announced a $5M seed round, with Lightspeed as lead investor and Kima and Ovni Capital following. The announcement generated interest from exactly the kind of players we were hoping to meet at the show.
A word of thanks
A genuine thank you to everyone who stopped by the booth to chat, test our demos, or just ask questions. And a special shoutout to Scaleway for welcoming the Kyber team on their booth for the entire four days, great partners make a difference.
See you at VivaTech 2027
The 10th edition of VivaTech was powerful, international, and full of real business. We came to show what we're building, meet the people shaping the industry, and prove that deep tech made in France is very much alive.
Mission accomplished.
We'll be back. See you next year 💎
