What Castle Hall does

Castle Hall (legal entity Entreprise Castle Hall Alternatives inc.) is a Montreal-headquartered institutional due diligence firm founded in 2007, positioned as the investment industry's largest dedicated due diligence provider. The company serves three principal customer segments: allocators (institutional investors such as pension funds, endowments, foundations, family offices, and sovereign wealth funds), asset managers (fund managers, hedge funds, PE firms, and alternative investment managers), and third-party service providers (fund administrators, prime brokers, custodians). Its core value proposition is risk assessment, operational validation, and portfolio monitoring for capital allocators evaluating external managers and counterparties.

The company's product architecture combines a technology platform with expert-led services. The DDX (Due Diligence Exchange) platform is the central data layer, holding standardized, independently verified profiles on more than 100,000 managers, funds, and service providers. DDX Pro is the flagship paid tier offering benchmark-driven portfolio analysis with peer comparison, while DDX Library provides off-the-shelf operational due diligence (ODD) reports and DDX Verification Reports are issued free to allocators for managers who have passed Castle Hall's "trust but verify" process. The proprietary DiligenceAI engine powers KYGP (Know Your General Partner), KYSP (Know Your Service Provider), and KYCO (Know Your Counterparty) profiles for early-stage research. OpsReview delivers human-analyst-driven institutional operational analysis, and DiligenceProfessional enables ongoing portfolio monitoring with anonymized analytics and benchmarking.

Castle Hall operates a freemium subscription model: basic profile searches on DDX are free, while detailed KYGP and KYSP profiles, Verification Reports, and DDX Pro require paid access. Go-to-market combines direct enterprise sales (expert-led consultative engagement) with self-serve digital access to the DDX platform. The company maintains its primary headquarters in Montreal and a regional office in Abu Dhabi to serve Middle East allocators, reflecting an explicit global footprint claim across North America and the Gulf. Revenue, funding history, and ownership structure are not publicly disclosed; the firm appears to be founder/management-controlled and privately held.
