What Marbury does

Marbury Corporate Advisory Services Limited is a Hong Kong-headquartered professional services firm founded in 2012 by Duncan Smith, specializing in cross-jurisdictional corporate and fund administration. The firm delivers seven integrated service modules: company formation and corporate secretarial services; accounting, audit, and tax; HR and payroll solutions (including MPF); visa and immigration services; fund solutions (administration, fund accounting, investor services, transfer agency, FATCA/CRS); corporate advisory (structuring, M&A, IPO support, risk management); and regulatory advisory (AML/CFT, economic substance, beneficial ownership compliance). Its primary clients are private equity and hedge fund managers, corporate entities operating across Hong Kong, Singapore, the UK, Bermuda, BVI, Cayman, Marshall Islands, Anguilla, and Seychelles, and family offices requiring bespoke cross-border structuring.

The revenue model blends annual recurring retainers (registered office, company secretary, accounting/payroll subscriptions) with transaction-based fees for ad-hoc work (share transfers, certificates of incumbency, special transactions invoiced in advance), plus project-based corporate advisory engagements. Distribution is sales-led via relationship managers and client service teams, supported by content marketing through publications, email newsletters, industry events, and a service enquiry form; pricing is not publicly disclosed and is governed by a standard scale adjusted for complexity, urgency, and risk on 30-day terms. The firm is licensed as a trust or company service provider in five jurisdictions — Hong Kong (HKMA), Cayman Islands (CIMA), BVI FSC, Bermuda (BMA), and Singapore (ACRA/MAS) — and holds ISAE 3402 Type II accreditation (audited by Baker Tilly for 2024) covering fund services operations.

The firm's technology stack centers on institutional-grade professional services delivery: the FIS fund administration platform (target platform post-integration), Xero cloud accounting integration with Xero-certified professionals, MailChimp for email, and Google Analytics for web telemetry. In December 2025, Ascentium — a Singapore-headquartered global business services platform comprising Harneys Fiduciary, InCorp Global, Links International, and Virtuzone — acquired Marbury, scaling the combined platform to 3,000 professionals across 57 cities and 27 markets serving 60,000+ client entities; Marbury will rebrand to Ascentium in May 2026 and relocated its Hong Kong headquarters in April 2026 as part of integration.
