What Woodbridge International does
Woodbridge International LLC, founded in 1993 in New Haven, Connecticut, and now wholly owned by Mariner Wealth Advisors following an August 2024 acquisition (rebranded to 'Mariner' in 2025), is a sell-side M&A advisory firm specializing in the sale of middle-market businesses with annual revenues between $10 million and $150 million+. The firm operates a proprietary 150-day timeline-driven auction process in which the closing date is established upfront, underwriting is completed within the first 30 days, and a 21-day Bid Acceptance Period follows launch; the process is supported by an in-house team that produces 2-minute custom marketing videos for each client and a proprietary database of 8,400+ private equity groups and 410,000+ strategic companies used to generate competitive bidding environments averaging 20 bids per closed transaction.
The firm monetizes primarily through transaction-based success fees on closed M&A engagements, with supplementary revenue from fee-based formal business valuations. Go-to-market is sales-led: managing directors and originators conduct direct outreach, supplemented by a content-marketing engine that includes 14 e-books, monthly newsletters, and an email list of 250,000+ business owners. Customer base is a diversified long tail of independent business owners across industries including wine, electrical services, industrial coatings, marketing, automotive services, and specialty manufacturing. Operations span North America (headquarters in New Haven; West Hartford office), South Africa (Cape Town), Europe, Asia, Latin America, and the Middle East, with WG Securities LLC (formed 2006, FINRA/SIPC-registered) operating as a wholly owned broker-dealer subsidiary. Post-acquisition by Mariner, the firm offers integrated post-sale wealth, estate, tax, and retirement advisory through affiliated Mariner entities, creating an end-to-end exit-to-wealth platform for sellers.
