Which insurance company is known for its 'Flo' mascot?

The insurance company known for its “Flo” mascot is Progressive.

Flo is a fictional Progressive salesperson played by actress and comedian Stephanie Courtney. The character first appeared in Progressive advertising in 2008, wearing a bright white uniform and presenting insurance shopping as a cheerful retail experience. Her repeated appearances made her one of the most recognizable figures in modern insurance advertising.

Flo is a spokesperson and fictional character, not the name of an insurance product or a separate insurer. Progressive's campaigns have also included recurring characters such as Jamie, played by Jim Cashman, and other employees and comic figures. That larger advertising universe sometimes causes viewers to remember the character more readily than the corporate name.

Progressive itself was founded in 1937 as Progressive Mutual Insurance Company and grew into a major American insurer, particularly in auto insurance. The company is also associated with comparison-style advertising that displays competing insurers' quotes alongside its own, reinforcing Flo's role as a guide to shopping for coverage.
