Kyber Raises $5M to Power Low‑Latency Control for Robots, Drones and Remote IT
Kyber’s low-latency SDK for real-time control of robots, drones and remote IT raised $5M led by Lightspeed to scale physical AI infrastructure globally.
Jean‑Baptiste Kempf’s startup Kyber has closed a $5 million funding round led by Lightspeed to commercialize a low‑latency infrastructure layer for remotely controlling robots, drones and distributed IT systems. The Paris‑based company says its SDK synchronizes video, audio, sensor feeds and control inputs with millisecond responsiveness, targeting applications where human operators or AI need real‑time control of distant devices. Kyber combines an open‑source core with enterprise services and will use the new capital to expand deployments, engineering capacity and global support.
Lightspeed leads $5 million round to back physical AI infrastructure
Kyber announced a seed round led by Lightspeed, the venture firm that has backed major AI players, signaling investor confidence in real‑time physical systems. Lightspeed described the investment as a bet on “physical AI” infrastructure that must operate reliably under tight timing constraints. The funding will be applied to product development, enterprise integrations and scaling the company’s global footprint across Europe, North America and Asia.
Real‑time synchronization built from streaming roots
Kempf, known for his work on popular open‑source media software, says Kyber’s performance focus comes from video‑streaming engineering and cloud gaming experience. The company’s SDK is designed to minimize latency by tightly coupling media streams and control channels, ensuring actions are executed in the real world with near‑instant feedback. That architecture prioritizes millisecond precision, which Kyber argues is essential when controlling robots, piloting drones, or remotely managing critical IT systems.
Open‑source core with enterprise product and services
True to Kempf’s background, Kyber maintains an open‑source foundation while selling a productized enterprise offering for customers that need hardened deployments. The startup pairs its software with forward‑deployed engineers who perform on‑site integration, tuning and ongoing support for large or sensitive systems. That hybrid model aims to lower adoption friction by giving developers an accessible SDK while offering commercial agreements and bespoke engineering for mission‑critical users.
Target sectors: robotics, drones and remote IT access
Kyber has prioritized three business segments: robotics fleets, aerial and ground drones, and remote IT access where latency and security are paramount. Early commercial deployments span defense, telecommunications, robotics companies and AI labs, according to the company. In remote IT, Kyber positions itself as a modern alternative for organizations that need low‑latency remote control and observability across distributed compute assets.
Scaling from thousands to millions raises observability stakes
Kempf highlights a central challenge: tools that work for fleets of a few thousand devices are not sufficient for the scale he anticipates as robots and drones proliferate. Managing millions of devices changes network patterns, update strategies and fault detection requirements, making observability and automated monitoring critical. Kyber is focusing on telemetry and system health tracking so operators — human or machine — can verify that control paths and sensory streams are functioning at scale.
Global team and commercial strategy
Kyber operates from Paris with additional offices in San Francisco and Singapore and employs roughly 25 full‑time staff, a significant share of whom serve as forward‑deployed engineers. The company says its go‑to‑market approach mixes open‑source community adoption with targeted enterprise sales in high‑need verticals. That strategy is intended to seed broad developer familiarity while capturing revenue from organizations that require secure, supported implementations.
Kyber’s proposition targets a timely junction of robotics, edge compute and AI control systems where latency becomes a limiting factor for new applications. As companies push more autonomy into the physical world, platforms that guarantee synchronized media, sensor data and control signals will be essential to safe and effective deployments. The new funding positions Kyber to broaden its technical footprint and support customers that require millisecond‑level responsiveness across dispersed devices.
