What Seabury Capital does

Seabury Capital Group LLC is a privately-held investment holding company founded in 1995 by John E. Luth and headquartered in New York, operating a diversified portfolio of specialty finance, investment banking, technology and software businesses concentrated in aviation, aerospace & defense, and financial services. The firm runs regulated advisory, restructuring and capital-markets activity through FINRA, NFA and FCA-licensed subsidiaries (Seabury Securities, Seabury Aviation Partners) and an SEC-approved Registered Investment Advisor (Seabury Capital Management, RIA since July 2025). Operations span 28 offices across 16 countries on five continents, supported by an enterprise client base of more than 500 organizations across 75+ countries and a 5,000+ engagement track record covering $350B+ of financing raised or restructured and $500B+ of aircraft orders and engine maintenance agreements.

The company's technology stack rests on proprietary platforms embedded in client workflows: Alkym and eAuthority (MRO and aviation regulatory software under Seabury Solutions); RAMP (trade-finance automation and credit analytics) and Billboard TFX (blockchain-enabled PaaS with ESG scoring, built with LSEG); FXone (decentralized Smart Order Router and OEMS) and Spotex (institutional FX and digital-asset liquidity and execution); plus SGI Aviation Services for technical asset management, 2-REG for aircraft registry services, TrakFin for receivables acceleration, SeaVS for vehicle service contract finance, and SeaCap Securities for secured working-capital financing. Distribution is direct and enterprise-led, augmented by event-driven marketing (Global Aerospace Summit, ISTAT, Airfinance Journal, Airline Economics Growth Frontiers) and thought-leadership content authored by senior partners.

Revenue is generated across four streams: regulated investment banking and advisory fees (transaction-based, multi-year engagements including M&A, restructuring and capital markets); proprietary software licensing (recurring subscriptions for MRO, regulatory, FX and digital-asset platforms); trade-finance transaction fees on the RAMP platform; and asset-management fees on $3.5B of AUM at year-end 2025. Pricing on advisory mandates is quote-based and engagement-specific, while software and asset-management revenues provide partial recurring offsets to the episodic nature of advisory wins.
