Intelligence for better decisions.

CTC Executives

CTC International Group, Inc. provides actionable intelligence to educate clients and help them make informed decisions. Headed by former Central Intelligence Agency officers, CTC employs the intelligence cycle to provide private clients with the same high quality process the U.S. Government uses to make decisions. Targeted research combined with professional analysis yields intelligence, not just “information,” which separates the “nice to know” from the “need to know.” CTC provides intelligence to CEOs, attorneys and other decision makers who need accurate, predictive, and actionable intelligence. Because knowledge really is power.

CTC has served private clients since 1992.
