Stratel AS

Stratel AS operates as a multi-family office based in Oslo. Reidar Lorentzen established the firm to serve multiple families with investment management and governance services. The structure centers on the Lorentzen family branch and extends to affiliated principals including Eline Synneva Lorentzen Ingstad and Mathias Lorentzen. The firm deploys capital through direct co-investments and SPVs rather than primary fund commitments. It holds positions in insurance via WaterCircles Forsikring ASA, hardware via reMarkable Invest AS, dairy via Rørosmeieriet, and energy via ZEG Power. Additional holdings include Aidee Health AS and Aivero. Geographic reach centers on Europe with documented co-investor ties that extend to North America and Asia. Investment stages span pre-seed through late stage. Team size remains undisclosed. Solvell AS serves as parent and largest shareholder per the Norwegian Business Register. Stratel AS maintains board roles in Backe Eiendom Invest AS and Friis & Friis AS through Erik Mathias Bjercke Lorentzen. No new operational events for the firm appear in the last 24 months. Stratel AS structures ownership through repeated co-shareholder arrangements with local Norwegian entities rather than standalone control. This model creates shared governance across portfolio companies and limits single-entity decision rights.
