What SGI Aviation Services does

SGI Aviation Services B.V. is an independent technical consulting and advisory firm serving the global aviation industry, headquartered in Amsterdam with offices in Clearwater (USA), Guernsey and Singapore, and technical representatives in 30+ countries. Founded in 2008 as the successor to International Aircraft Management B.V., the company operates in partnership with its parent Seabury (a global advisory and investment bank) and offers four core service pillars covering the full lifecycle of aviation assets: Aircraft Management (asset analysis, valuation, inspections, remarketing, expert witness support, repossessions), Engine Services (fleet management, shop-visit management, inspections, negotiations, storage across all commercial turbofan and turboprop engines), Regulatory Services (SMS implementation, Part 145/AOC/ATO certification assistance, audits, training, temporary aircraft registration), and IT Services built around a proprietary Digital Records Management System. Its primary customer segments are lessors and financiers, commercial airlines, corporate aircraft owners, with secondary engagement in aircraft manufacturers, MROs and aviation authorities.

The firm monetizes exclusively through professional services — quote-based project engagements, ongoing asset and lease management mandates, transaction success fees on aircraft and engine sales/leases, and bespoke advisory mandates — with no public pricing. Its underlying technology stack combines licensed aviation engineering expertise with proprietary software assets: a Digital Records Management System supporting aircraft transfer and audit preparation, an Aircraft Valuation Forecasting Model that adjusts current market value to maintenance status, and an Engine Management Tool that optimizes maintenance planning. Differentiators center on independence (no OEM/lessor/MRO affiliation), a globally distributed talent bench of licensed engineers and former airline/MRO/lessor executives, and a deep transaction track record across narrowbody and widebody aircraft (private jets to A380s), with 2023 volumes including 65 redeliveries, 75 engine re/deliveries, 45 shop visits, 105 pre-purchase inspections, 60+ asset-managed aircraft and engines, 30 lease reviews, and 250 cash-flow analyses across more than 12,000 mandays.

SGI reaches customers through direct enterprise advisory engagements led by its senior leadership and regional offices, supplemented by industry conference presence (Airfinance Journal Asia Pacific, Aero-Engines Europe, Ishka Korea), a transaction-focused content/news footprint, and a growing LinkedIn profile. Despite a private ownership structure under Seabury, the firm has no disclosed funding rounds, no venture backing, and operates an asset-managed portfolio including relationships with MUFG-owned BOT Lease, Philippine Airlines, Turkmenistan Airlines, DHL, and ex-Cathay Pacific / Garuda Indonesia widebody remarketing mandates.

Expansion highlights5 records

Broad incumbents

• Cirium: Cirium (including the Ascend by Cirium brand) is the leading aviation data and analytics provider offering valuations, market intelligence, and advisory at much wider scale than SGI; a broad incumbent whose data products intersect with SGI's advisory mandates.
• KPMG (Aviation Industry Practice): KPMG's Global Aviation practice provides advisory and transaction services to airlines, lessors, and airports — overlapping with SGI's transaction and asset advisory work as a larger, diversified consulting incumbent.
• Oliver Wyman (Aviation Practice): Oliver Wyman operates a global aviation practice serving airlines, lessors, and MROs with management consulting — comparable to SGI's airline consultancy and asset management offerings but as part of a much broader portfolio.

Others

• Seabury Capital: Seabury Capital is SGI's parent company, a global advisory and investment banking firm serving aviation clients; not a direct competitor but an enabling/adjacent relationship that provides SGI with cross-sell into IB and restructuring mandates.

Direct peers

• Alton Aviation Consultancy: Alton Aviation is a specialized aviation advisory firm offering management consulting to airlines, lessors, MROs, and investors — directly overlapping SGI's client base across commercial aviation strategic and operational advisory mandates.
• Avitas: Avitas is a boutique aviation consultancy specializing in aircraft and engine valuations, market intelligence, and asset advisory for lessors, airlines, and financiers — directly comparable to SGI's core aircraft and engine asset management services.
• IBA Group: IBA Group is an aviation consultancy focused on aircraft and engine values, lease advisory, and market intelligence. Like SGI, it serves lessors and airlines with technical and commercial asset management advisory across the aviation lifecycle.
• Morten Beyer & Agnew: MBA is an aircraft and engine valuation and advisory firm serving financial institutions, lessors, and operators with appraisal and consulting services — highly comparable to SGI's valuation, inspection, and remarketing offerings.
