What TenAsys does

TenAsys Corporation is a privately held U.S. software vendor specializing in deterministic real-time operating systems for industrial automation, embedded systems, and motion control on x86 multicore hardware. The company's flagship product line, INtime, runs alongside Microsoft Windows or Linux on the same platform through Intel VT-based hardware partitioning and the Real-Time Systems (RTS) hypervisor, enabling workload consolidation that replaces separate proprietary PLC hardware with consolidated industrial PCs. The portfolio spans INtime RTOS (bare-metal real-time), INtime for Windows (co-deployment with Windows), INtime Distributed RTOS (multi-node distributed virtualization), the INtime SDK (Visual Studio-integrated, with Boost C++ Libraries and IEC 61131-3 PLC environment support), and the INtime License Portal plus the TenAsys Platform Assessment Tool (TPAT).

TenAsys monetizes through commercial software licensing — including node-locked, entitlement/SUAC-based, and network license server configurations — paired with annual maintenance and support contracts; free evaluation licenses support the top of funnel. The company sells directly to industrial OEMs and through a global distributor network plus a deep partner ecosystem spanning platform providers (Advantech, Kontron, Nodka, ASRock Industrial, AAEON, Portwell, Concurrent Technologies, RTS/congatec), middleware/protocol vendors (acontis, koenig-pa, straton, TSEP, esd electronics, HMS, Hilscher), and development tool vendors (AXEL, ISAC, ISG, RSI). The TSN-enabled platform supports EtherCAT, Sercos III, OPC UA, Profinet, Modbus, and MQTT, and is integrated with Intel TCC for deterministic networking and timing.

Named end customers include KUKA, Yaskawa, Omron, Lenze, Phoenix Contact, Beckhoff, KEB, Aerotech, Estun, Biesse Group, HOMAG, Nodka, Hilscher, RSI, Optel, and ISAC, spanning industrial automation, robotics, CNC, motion control, packaging, and test & measurement verticals. The company is founder-led (CTO/Founder Christopher Main), employs 11-50 people, is headquartered in the United States, and has been operating for more than 40 years in deterministic computing; it shows no funding rounds, acquisitions, or public listing signals.
