Seior Capital Partners, based in Oslo, Norway, was founded by Trond Tviberg and Mads Andreassen in December 2021. The investment team launched the Seior Healthcare Opportunities Fund – a directional long/short equities fund, in September 2022.

The investment strategy utilizes a bottom-up stock selection process, with the core focus on fundamental valuation and incorporating several sustainability criteria. Before establishing Seior Capital Partners, the co-founders worked in a healthcare team for over ten years where they co-managed a market-neutral strategy and a long-only UCITS fund.
