Leeham Co LLC was formed by Scott Hamilton in 1999 after the sale of the company he co-founded, Linkraven Ltd. Linkraven was formed in 1989 and published Commercial Aviation Report and Commercial Aviation Value Report and produced global conferences under the name Commercial Aviation Events. Commercial Aviation Report quickly became a leading source of news in airline and aircraft finance while Value Report brought to the forefront the world of aircraft appraisals. Events produced 60 conferences in 10 years, including the first aviation finance conference in Eastern Europe following the fall of the Iron Curtain; the first in Moscow; and the first in Beijing.

Leeham is a globally recognized expert in aerospace issues, focused on the Big Four airframe Original Equipment Manufacturers (Airbus, Boeing, Bombardier and Embraer) and the engine OEMs. Leeham provides aviation consulting focusing on business strategy, competitive intelligence. Clients seek industry trends and forecast for their strategic planning. The Washington State Dept. of Commerce retained Leeham in 2009 to create an aerospace policy. Leeham Co. services only the aerospace industry.

Hamilton was on the Board of Directors for the Pacific Northwest Aerospace Alliance, Seattle, from 2010-2013. PNAA is a supplier trade group servicing Washington, Oregon, Idaho, Montana, British Columbia and Alberta.

The annual conference attendance increased by 300%.
