Jonathan Rosenthal

CEO, Saybrook Management

Jonathan Rosenthal is a serial entrepreneur. He has repeatedly conceived of a world different than that which existed, and launched companies to harness macro industry change. Each new venture was designed to capture opportunity, as consumers adapted to transformation.

In 1983 he recognized the inevitable upheaval in transportation that would come after deregulation of the airline industry and the end of the Civil Aeronautics Board. In anticipation, Rosenthal launched his first company – NetAir International. He foresaw the realignment of airline networks from point to point service to a hub and spoke system and the difficulties that would befall time sensitive executives. The solution was to disrupt the localized and fragmented jet charter business by building the first multi-city on demand jet charter company, providing immediate access through centralized dispatch, standardized training, national accounts, and uniform branding.

That which now seems obvious wasn’t easy to evangelize in ‘83. But with the help of active investors Jay Chiat, Linden Blue, Wally Schirra, Honorable John Lindsay, Hycliff Ventures and others NetAir was born. As Chairman and CEO Mr. Rosenthal grew NetAir into the largest certificated non-scheduled carrier in the U.S with 18 flight centers and over 100 jets providing “random access” transportation to 1,700 cities. A public offering in 1985 helped spur growth, and in 1989 Rosenthal successfully exited with a sale of his shares to a private equity investor at time when rival NetJets had a dozen aircraft.

Again seizing upon transformation, in 1990 Rosenthal saw the proliferation junk bonds of the 80’s creating distressed opportunities. Rosenthal launched Saybrook Partners, a merchant bank specializing in complex municipal and corporate turnarounds and restructurings. Timing was fortuit
