What Strainlabs does

Strainlabs AB is a Swedish industrial IoT company, headquartered in the IDEON science park in Lund with additional offices in Stockholm and Tranås, that has developed IoT-enabled "smart bolts" with patented LED sensors capable of continuously measuring bolt preload and temperature (144 measurements per day) and transmitting the data wirelessly through gateway routers to a cloud-based Strainlabs Analytics platform. Its product portfolio comprises five components — sensorized bolts, wireless routers, the cloud analytics platform, a Bluetooth-enabled mobile verification app (Strainlabs App, launched April 2026), and the integrated Strainlabs System — that together convert passive mechanical fasteners into active data points for predictive maintenance.

The company sells to industrial enterprise customers across at least seven verticals (manufacturing, mining, railway, energy, infrastructure, machine building, and process industry) through a consultative enterprise field-sales motion led by Sales Manager Gösta Rydin, with pilot installations on critical joints as the standard entry point and a "Request a demo" conversion mechanism on the website. Distribution is supplemented by technology-partner channels — most notably a 2024 partnership with Railway Metrics and Dynamics (RMD) that integrates Strainlabs bolts into RMD's real-time monitoring platform — plus app-store distribution for the mobile app. Revenue streams include hardware sales (bolts typically 100-200 SEK, specialized applications up to ~1,500 SEK per bolt, plus routers), a recurring cloud-analytics subscription, and a freemium mobile app.

The company was founded in 2014, is privately held under Swedish AB corporate form (organization number 556958-8386), has been sustained by venture capital (seed investment led by 3T Invest) through an R&D phase, and is transitioning from startup to scale-up status. Named customers include Boliden (mining jaw crusher and mobile loader), Öresundsbron (Öresund Bridge predictive-maintenance pilot), Seaflex and EDP (floating solar mooring monitoring in Portugal), Gröna Lund (amusement-park ride safety), Nynas (hazardous-environment process monitoring), CAF (railway component loads), RMD, and SSAB/Väte Trafik (locomotive axle-bearing monitoring).

Core offering

Strainlabs designs, manufactures, and sells IoT-enabled sensorized bolts with patented LED-sensor technology that continuously measure bolt preload and temperature. The offering includes the smart bolts, wireless routers, a cloud-based analytics platform, and a mobile companion app, sold as an integrated monitoring system that delivers real-time data on bolted-joint integrity for industrial customers.

Product overview

Strainlabs offers a unified IoT-based bolt monitoring solution centered on its smart sensorized bolts with patented LED technology. The product portfolio consists of five interconnected components: (1) Strainlabs Bolts – smart hardware with built-in preload and temperature sensors; (2) Strainlabs Routers – gateway devices for wireless data transmission; (3) Strainlabs Analytics – cloud-based monitoring and visualization platform; (4) Strainlabs App – mobile companion app for direct Bluetooth-based field verification; and (5) the Strainlabs System – the complete integrated solution tying all components together. The system enables continuous 24/7 monitoring with 144 measurements per day, delivering data to both the cloud platform and a mobile app for comprehensive coverage of industrial bolted joint integrity.

Broad incumbents

• National Instruments (NI): NI (now part of Emerson) builds test, measurement, and data-acquisition hardware and software used for strain, vibration, and electrical signal monitoring in industrial and laboratory settings. Comparable as a measurement-instrumentation platform that could integrate or compete with Strainlabs' analytics layer.
• ifm electronic: ifm electronic produces industrial sensors and IO-Link condition-monitoring solutions used in factory automation and process industries. Comparable as a broad industrial sensor vendor whose portfolio overlaps with Strainlabs' monitoring and analytics layers.
• Banner Engineering: Banner Engineering manufactures industrial sensors, wireless monitoring devices, and IIoT gateways used in factory automation. Comparable as an industrial sensor incumbent with wireless/IoT capabilities overlapping Strainlabs' router-and-sensor architecture.
• HBK (Hottinger Brüel & Kjær): HBK is a global leader in strain gauges, load cells, and force/torque measurement — the underlying measurement category Strainlabs bolts fall into. Comparable because both sell industrial force/strain sensors; HBK is far broader in scale and customer base.
• SKF (Condition Monitoring): SKF's condition monitoring business sells wireless sensors and analytics for rotating equipment and industrial assets. Comparable as an industrial IoT condition-monitoring vendor with a far larger installed base and brand presence than Strainlabs.
• Pepperl+Fuchs: Pepperl+Fuchs manufactures industrial sensors (including vibration, force, and wireless condition-monitoring devices) for harsh environments. Comparable as an industrial sensor incumbent with wireless/IoT capabilities adjacent to Strainlabs' offering.

Emerging players

• Monnit: Monnit offers a broad catalog of wireless IoT sensors (temperature, voltage, vibration) with cloud monitoring software targeted at industrial and asset-monitoring applications. Comparable as a wireless sensor + cloud platform vendor serving industrial condition-monitoring buyers.
• Augury: Augury provides AI-driven machine health and condition-monitoring sensors and software for industrial customers. Comparable as a software-anchored IoT condition-monitoring vendor targeting similar predictive-maintenance use cases, though Augury focuses on vibration rather than bolt preload.

Direct peers

• Vishay Precision Group: Vishay Precision manufactures foil and strain-gauge sensors for force, weight, and stress measurement. Directly comparable as a sensor company focused on strain/force measurement used in structural health and industrial monitoring applications.
• SmartBolts (Nord-Lock Group): SmartBolts (part of the Nord-Lock bolted-joint technology group) offers visual bolt tension indicators used to detect loose fasteners. Highly comparable end-use (monitoring bolt preload on critical joints), though the mechanism is visual rather than electronic.
