Nathan Owen Rosenberg Sr.

Founding Partner – California

An executive’s executive with an entrepreneurial mindset, Nathan Owen Rosenberg not only co-founded Insigniam, but also founded two other successful enterprises and has served as chief executive of four corporations.

His expertise and experience gained from working with more than 70,000 people during his 28 years in consulting has resulted in measurable Breakthrough Results, enterprise innovation, and leadership transformation.

Nathan’s innovation consulting with a well-known consumer goods company produced more than $200 million in new revenue in the first year. He advised a leading global clothing and lifestyle company to take a new approach in updating their ERP system, reducing the upgrade time in half.

He consulted with the EVP of Global Operations, managers and union leadership at an American aerospace manufacturing company, resulting in reduced costs, improved quality and increased throughput in a 10-month timespan. Employee satisfaction increased as well, rising from the bottom quartile to the seventh decile of all manufacturers.

During the engagement, shareholder value increased more than 600 percent compared to falling share prices in the previous three years.

He led the company’s transformation and turnaround, tripling the company’s value in four years by regaining contracts with the U.S. military and greatly expanding demand from scuba divers.

He was also an executive in the West Coast’s largest minority-owned advertising agency and a managing partner in a national real estate investment firm. As a young man, he was an officer and aviator in the United States Navy and served as the secretary of defense’s executive support officer and national security advisor to the U.S. senate majority leader.
