What Teracom does

Teracom is a Bulgarian-based manufacturer of industrial-grade remote monitoring and data acquisition (SCADA) hardware, founded in 1993 and headquartered in Ruse, Bulgaria. The company designs and produces Ethernet and cellular (4G LTE) controllers, I/O modules, and a comprehensive portfolio of 1-Wire and MODBUS RTU sensors covering temperature, humidity, CO2, barometric pressure, AC voltage, water leak detection, and S0 pulse counting. Its technology stack supports the major industrial and IoT communication protocols including MODBUS RTU/TCP/IP, MQTT, SNMP, and HTTP/HTTPS, with native integrations to AWS IoT Core, Microsoft Azure IoT, HiveMQ, ThingsBoard, Node-RED, and major telematics platforms (Teltonika, Ruptela, Queclink, Xirgo Global).

Teracom operates an exclusively channel-based go-to-market model, selling all products through a network of authorized distributors spanning 51+ countries with no direct e-commerce or publicly disclosed pricing. The company monetizes primarily through one-time hardware sales, supplemented by software offerings including the TC Monitor Windows SCADA application and Android/iOS mobile apps. End customers span industrial and telecom infrastructure (primary segment), manufacturing/factory automation, agriculture (notably orchard frost protection via partner FruitProtect), building automation/HVAC, and maritime safety systems.

The company is privately held with 1-10 employees, no disclosed external funding, and no parent company. Over its 32-year history, Teracom claims 2,300+ designs developed and 1.36M+ items shipped, accumulating 630+ man-years of engineering experience. Recent strategic emphasis is on IoT-readiness, cellular data efficiency (more than 90% reduction in data usage through MQTT optimization in the TCG120-4), and expanding the telematics and IoT platform integration ecosystem.
