Safety Bolt

Safety Bolt is a Stockholm-based Swedish deep tech company developing an industrial IoT sensor system that measures strain in bolts and surrounding structures. Reinforcing bolts are presented as a fundamental safety component of built structures, where a failure can cause loss of life, operational downtime and wider societal impact, making bolt-strain measurement a business-critical function. The company's offering combines patented sensor hardware with proprietary machine learning algorithms, positioned for use in wind turbines, bridges, tunnels, rail and mining sites.

The company describes its third-generation material stress sensor as being at technology readiness level 5, validated by Atlas Copco and unnamed confidential industry partners. It targets predictive maintenance use cases intended to reduce maintenance cost and extend the life cycle of heavy industrial and infrastructure assets. Claimed effects published by the company include reducing operational maintenance costs by up to 20%, avoiding unplanned downtime valued at up to $1 million a day, and improving worker safety in heavy industry sites.

Business model

B2B. The company works with industry leaders in its key segments as paying clients that run pilots, with the aim of scaling up its sensor technology from those deployments.

Traction

The company reports a recent commercial contract with one of its partners and collaboration with industry leaders as paying pilot clients. Its sensor has been validated by Atlas Copco and confidential industry partners. A senior mining client is quoted describing the product's value for monitoring structural integrity of mines. As of the listing, the company had five open roles in Stockholm, including Senior Embedded Systems Engineer, Chief Operating Officer, Mechanical Engineer, Founder's Associate, and Sensor Systems & Validation Engineer.
