Kyber: The VLC Creator's $5M Startup Building a Real-Time 'Nervous System' for Robots and Drones

Kyber is a Paris-based deep-tech startup founded by VLC Media Player creator Jean-Baptiste Kempf. It raised a $5 million seed round in June 2026 to build an open-source, ultra-low-latency infrastructure layer — essentially a "nervous system" — for controlling robots, drones, autonomous vehicles, and other physical devices in real time over the internet.

What Kyber Is Building

Kyber's core product is an SDK (software development kit) that synchronizes video, audio, sensor data, and control signals with sub-millisecond latency. The goal is to make remote machines feel as responsive as if the operator were sitting right next to them.

The problem Kyber solves is fundamental: existing internet infrastructure was built for file sharing and streaming, not for teleoperating hardware. Even small delays make it impossible to drive a remote vehicle or control a robot arm safely. Kyber treats latency as the primary constraint and rebuilds the data pipeline from the ground up.

Target Use Cases

Kyber's technology applies across several high-stakes domains:

• Robotics: Teleoperation and fleet management of warehouse, factory, or field robots with near-zero lag.
• Drones: Real-time video feed and control for inspection, delivery, or surveillance drones.
• Remote Vehicle Control: Driving or piloting vehicles from a distance, such as autonomous vehicle backup centers.
• AI Visual Agents and Immersive Environments: Low-latency video and sensor streams for AI systems that need to see and act in real time, including VR/AR and embodied AI.

Funding and Investors

Kyber's seed round details are straightforward:

• Amount: $5 million (approximately €4.3 million).
• Lead investor: Lightspeed Venture Partners.
• Co-investors: OVNI Capital and Kima Ventures.
• Legal advisor: Morgan Lewis advised Lightspeed on the deal.

Lightspeed's bet on Kyber is notable: the same firm has backed prominent AI companies like Anthropic and Mistral AI.

The Team and Why Kempf Is the Right Person

Kempf is the lead developer of VLC (over 6 billion downloads) and the primary architect of FFmpeg, one of the world's most widely used video-processing libraries. Both projects are renowned for handling complex, latency-sensitive media streams at massive scale on minimal hardware. Kyber applies the same engineering philosophy — open-source, efficient, multi-platform — to the physical world.

The company currently has 25 employees across offices in Paris, San Francisco, and Singapore.

The Bigger Picture: Physical AI

Kyber positions itself at the center of what it calls the "Physical AI era" — a future where hundreds of millions of robots and drones operate on streets, in warehouses, and in the air, all requiring real-time human or AI oversight. Kempf has described Kyber as the infrastructure layer that will make this vision practical by providing an end-to-end software stack for server, client, and protocol, so developers can focus on their drones, robots, or immersive worlds without worrying about latency, synchronization, security, or networking.
