In addition to his government service, Kian became active in consulting and strategic advisory work. He co-founded Flynn Intel Group alongside retired U.S. Army Lieutenant General Michael Flynn. The consulting firm worked on projects related to international affairs, business strategy, and geopolitical analysis. Through this work, Kian became involved in discussions surrounding foreign policy and international lobbying.
Public attention toward Kian increased significantly due to legal proceedings connected to lobbying activities involving Turkish interests. U.S. prosecutors alleged that certain activities undertaken by associates of Flynn Intel Group should have been registered under laws governing representation of foreign interests. The legal case generated widespread media attention because of its political implications and its connection to broader investigations occurring during that period in American politics.
