Thor's Haven builds ultra-mobile, modular micro-infrastructure for military and humanitarian operations in conflict zones and crisis environments. Its product range — including medical stabilisation points, dental clinics, mobile command centres for UAV operators, and CASEVAC quad-bike trailers — is built on a single standardised trailer chassis towable by any standard vehicle and deployable within minutes. All units are manufactured at the company's workshop in Lviv, Ukraine.

Founded by Estonian volunteers Erko Laidinen and Torhalla-Maarja Metsniin, whose combined frontline experience in Ukraine since 2022 shaped every design decision, Thor's Haven began as a volunteer initiative in summer 2023 and formally incorporated in February 2026. Its products have been co-developed with and deployed across 12+ units of the Ukrainian Armed Forces, including the 125th Heavy Mechanized Brigade and the 93rd Brigade "Kholodnyi Yar."

The company operates as part of the Bifrost Defence portfolio — a Copenhagen-based defence venture builder holding a 50% stake — which provides strategic oversight, growth capital, and European market access. Thor's Haven generated EUR 927K in revenue from January to May 2026 and was planning an equity raise opening in late 2026. The company is expanding its platform into European NATO markets.
