Bill is founder and president of Teal Group, a company he established in 1987 to provide business intelligence for the worldwide aerospace and defense community. The company currently comprises six analysts and several other support personnel. Primary activities focus on the forecast of the production of, and the markets for, a wide variety of aerospace and defense equipment, including military and civilian aircraft, missiles and smart munitions, spacecraft and launch vehicles, and electronics.

Teal employs "open source intelligence" techniques to gather its information, i.e., no classified or proprietary sources are used. Findings are published in a series of monthly updated report compilations called Briefing Books. Also, the company is involved in providing consulting services to a variety of US and international companies and governments.

These included World Military Aircraft Forecast, World Helicopter Forecast, International Defense Budgets, Top 500 RDT&E Companies, World Armored Vehicle Forecast, Remotely Piloted Vehicles, and Surveillance & Reconnaissance.
