Positron Capital

Positron Capital is a partner-owned asset manager in Oslo, regulated by Norway's Financial Supervisory Authority as an AIFM. Founding partners Christian Bryn, André Bjørntvedt, and Øyvind B. Haddeland draw on careers in London, Zurich, and Oslo to source and manage private-market commitments. The firm structures its work through a mix of commingled specialist funds and tailored discretionary accounts, with track-record claims reaching back over 20 years and cumulative deployment above EUR 1 billion across strategies. Investment conviction flows into four private-market asset classes: private equity, infrastructure, private debt (including direct lending), and secondaries. The firm describes a high-conviction bias toward small and mid-sized opportunities — the part of the market where it argues active ownership can generate 'real alpha' uncorrelated to broad benchmarks. Positron runs both fund-of-funds commitments and direct co-investments, leaning on a network built over decades to find managers that do not widely market their vehicles. No specific portfolio companies or fund names are published on its website, consistent with a firm that stresses discretion over broadcast transparency. The professional count is not disclosed, though the public-facing senior team numbers six people across investments, operations, compliance, and the chair. Operating from a single office in Oslo, the firm manages capital on behalf of life insurance companies, pension funds, banks, foundations, family offices, and private individuals. All funds under management are classified as SFDR Article 6 — sustainability risks are integrated into investment decisions, but the vehicles do not promote environmental or social characteristics. Unlike large multi-strategy platforms that combine in-house deal teams with third-party fund selection, Positron functions as a pure intermediary: it does not originate direct deals independently but marries manager selection, co-investment access, and tailored portfolio construction under a single, owner-operated roof. The partnership structure means the people writing the investment tickets also run the business, compressing fee layers and preserving the alignment they pitch to allocators.
