What Altosens Gmbh does

Altosens GmbH is a Fraunhofer spin-off founded in 2022 and headquartered at the Innovationszentrum Osnabrück in Lower Saxony, Germany. The company develops and sells intelligent sensor washers (altosens.disc) that measure bolt preload forces in real time and transmit the data digitally via a CAN bus interface. Its technology is based on decades of sensor and measurement engineering research conducted at the Fraunhofer Institute LBF, with the sensor washer designed to match standard DIN washer dimensions from size M20 for retrofit into existing bolted connections.

The product portfolio is modular: the altosens.disc sensor feeds data to altosens.edge or altosens.edge-ai gateways (supporting up to 127 sensors with Wi-Fi, Ethernet, or LTE connectivity), which route information to the altosens.stack software platform (Docker-based, REST API, MQTT, Kafka) and altosens.cloud for cross-site monitoring, visualization, and alerts. Edge AI-based anomaly detection is positioned as a core capability for identifying loosening bolts and predicting failures before they occur. Target use cases are safety-critical bolted joints in wind energy turbines, infrastructure (bridges, towers, buildings), and agricultural/logistics machinery.

The business model combines industrial hardware sales (sensor washers and gateways) with what appears to be recurring software and cloud subscriptions. GTM is an enterprise field-sales motion targeting wind operators, infrastructure owners, and agriculture/logistics companies in Germany, with quote-based pricing requiring technical consultation and customization per deployment. The company has 11+ team members and is led by Managing Director Uwe Steinkamp and co-founders Jan Hansmann and Dr.-Ing. Sebastian Rieß.

Core offering

Altosens GmbH manufactures and sells intelligent IoT sensor washers (altosens.disc) that retrofit onto bolted joints to provide continuous structural health monitoring. The company bundles this hardware with edge gateways (altosens.edge / altosens.edge-ai), edge/on-prem software (altosens.stack), a management tool (altosens.core), and a cloud platform (altosens.cloud) to deliver an end-to-end predictive maintenance solution for industrial operators.

Product overview

Altosens offers a modular IoT monitoring system for safety-critical bolted joints. The core product is altosens.disc, an intelligent sensor washer that measures bolt preload forces. This sensor integrates with gateway devices (altosens.edge or altosens.edge-ai with AI processor) that collect data from up to 127 sensors and transmit it to the cloud. Software consists of altosens.stack, a Docker-based platform providing real-time monitoring and anomaly detection, which includes altosens.core for sensor management. The altosens.cloud service adds centralized cross-site data storage, visualization, and remote monitoring. Together, these components enable predictive maintenance for wind energy, infrastructure, and agricultural applications.
