What Attestor Capital LLP does

Attestor Capital LLP operates as a value investment firm headquartered at 7 Seymour Street, London, W1H 7JW, England, with operating entity Attestor Limited registered in England and Wales (company number 12080120). Established in 2012, the firm is authorised and regulated by the UK Financial Conduct Authority (FCA registration 911816) and deploys long-term, patient capital into global investment opportunities.

The firm does not build or sell technology products; its offering is investment management services aimed at institutional investors and high-net-worth individuals seeking long-duration value exposure rather than short-term trading returns. It monetises through standard asset-management economics: recurring management fees charged on assets under management, supplemented by performance fees tied to investment returns, with all fee terms negotiated privately with clients.

Distribution is direct and relationship-driven — the firm engages pension funds, endowments, family offices and HNW investors via a sales-led motion supported by professional referrals and a dedicated in-house recruitment and enquiries function. Public disclosures cover FCA prudential reporting (MIFIDPRU 8), climate (TCFD) and stewardship obligations, but financials, AUM, headcount, ownership, and investor composition are not publicly disclosed.
