What QuaternAR does
QuaternAR (legally QUATERNAR a.s.) is a privately held Czech joint-stock company headquartered in Prague that develops QAROS, a device-agnostic extended-reality (XR) streaming software development kit. QAROS connects existing 3D applications — written against DirectX, Vulkan, OpenGL, or CPU-based renderers — directly to AR and VR headsets, 3D displays, desktops, and tablets by streaming pixel data from desktop or server-side rendering hardware to the end device, rather than re-streaming geometry or requiring engine migration. Multi-engine interoperability, mixed-device sessions, encrypted streams with no on-device data persistence, and self-hosting for full control are positioned as core architectural features. The product is supported by the Quaternar Remoting Library, which handles AR/VR streaming and head-tracking synchronization and serves as the technical foundation for QAROS.
The company is founder-led (CEO Jan Hovora) with a four-person engineering team (Vision Engineer Lukáš Jelínek, Software Engineer Richard Molnár, Graphics Engineer Jaroslav Vozár) and currently generates revenue through QAROS SDK licensing via direct enterprise sales and channel partnerships. Distribution is anchored by a flagship October 2025 strategic partnership with DigiLens Inc., which makes QAROS available to DigiLens ARGO AR glasses customers through the Digi SaaS platform, opening the U.S. defense, government, and first-responder markets for tactical and operational planning use cases.
QuaternAR pursues enterprise customers in defense, government, and public-safety segments, evidenced by I/ITSEC 2025 exhibition and presentation activity. Marketing is conducted through content (company blog, LinkedIn, YouTube) and industry events rather than paid acquisition. No funding rounds, parent company, named end customers, certifications, patents, or disclosed revenue figures appear in the available data; ownership appears to remain with the founders.

QuaternAR product offering
Product offeringCore offering
QuaternAR develops and sells QAROS, a device-agnostic XR streaming SDK that connects existing 3D software — built on DirectX, Vulkan, OpenGL, or CPU-based renderers — directly to AR and VR devices without engine migration or reimplementation. It streams pixel data from desktop or server hardware to headsets, 3D displays, and tablets, enabling real-time collaboration across multiple applications from different vendors in a single shared 3D environment.
Product overview
QuaternAR offers QAROS, a unified XR streaming middleware platform, and the Quaternar Remoting Library as its technical foundation. QAROS connects existing 3D software directly to AR and VR hardware without requiring engine migration, reimplementation, or new tooling. It streams pixel data from desktop or server rendering hardware to a range of devices including AR glasses, VR headsets, 3D displays, desktops, and tablets, enabling multi-user shared scenes. The Quaternar Remoting Library handles the low-level AR/VR streaming and device synchronization that underpins QAROS capabilities.
